ABSTRACT

During preparation of the account of the genus Millettia (Fabaceae: Faboideae) for the Flora of Thailand, some new field collections and specimens from herbaria were found to represent three new species, and here they are described and illustrated with a distribution map. Lectotypes of Millettia names are designated for nine species, five new synonyms of Millettia are proposed and Millettia tecta is raised to species status.

KEYWORDS: Generic circumscription, Leguminosae, Millettieae, taxonomy

 Millettia phuwuaensis Mattapha & Suddee, sp. nov.

This species is similar to Millettia penicillata Gagnep. in having distinct red lines on the outer surface of the standard, but differs in its fewer leaflets (5–7 vs 9–17 in M. penicillata), shorter pseudoracemesor pseudopanicles (up to 10 cm long vs 8–28 cm in M. penicillata), monadelphous stamens (vs diadelphous stamens in M. penicillata) and a tubular disk (vs disk absent in M. penicillata).

Vernacular.— Phan na rai phu wua (พรรณรายภูวัว).

Etymology.— The specific epithet refers to the type locality.

Notes.— Millettia phuwuaensis has distinctive red lines and dense puberulent hairs on the outer surface of the standard. The reddish lines look super-ficially similar to those of M. penicillata but are thicker and more unevenly scattered (vs parallel in M. penicillata). Additionally, Millettia phuwuaensisis recognised by its narrowly obovate and larger standard petal (14–15 × 12–13 mm vs orbicular and 8–9 × 9–10 mm in M. penicillata).

Millettia pyrrhocarpa Mattapha, Forest & Hawkins, sp. nov.

This species is similar to Millettia sericea (Vent.) Wight & Arn. ex Hassk., in having ferruginous hairs on the exocarp surface of the fruits, but differs in its caudate leaflet apices (rather than the acute or retuse apices in M. sericea). The lower leaf surface is densely hairy along the midrib, but otherwise glabrous (vs densely sericeous throughtout in M. sericea), the standard petal has basal callosities tapering into the claw (vs basal callosities absent in M. sericea), and brachyblasts carry ca 3 flowers (vs 10 or more in M. sericea).

Vernacular.— Nang rong (นางรอง).

Etymology.— The specific epithet refers to the densely ferruginous hairy fruits.

Notes.— Millettia pyrrhocarpa was collected in the same locality by different collectors, but has remained unrecognised as a new species. We found it amongst unidentified collections with other unnamedMillettia specimens, therefore, only when we had identified flowering and fruiting material could we confirm that it was a new species based on the standard having basal callosities tapering into the claw, presenceof ca 3 flowers on the brachyblasts and the fruits covered with densely ferruginous hairs. Because of the ferruginous indumentum on the fruits, the species was compared with the most similar species, M. sericea. It differs from M. sericea in its smaller and thinner leaflets lacking sericeous hairs on the lower surface, and smaller standard petals (8–9 × 8–9 mm vs 10–13 × 10–12 mm in M. sericea), lacking sericeous hairs on their outer surface (vs densely sericeous in M. sericea).

 Millettia suddeei Mattapha & Tetsana, sp. nov.

This species resembles Millettia puerarioides Prain, but differs in having stipels (stipels absent in M. puerarioides), sparsely pubescent hairs on the lower surface of the leaflets (vs densely silky hairs in M. puerarioides), and diadelphous stamens (vs monadelphous in M. puerarioides). It is also characterized by having 7–9 leaflets (vs 5–7 in M. puerarioides), and a standard petal with pubescent hairs on the outer surface (vs densely silky hairs in M. puerarioides). 

Vernacular.— Phi lai somran (พิไลสมราน).

Etymology.— The epithet refers to Dr. Somran Suddee, who first collected the species.

With more than 60 currently accepted species, Thismia Griffith (1844: 221) is the largest genus of the tribe Thismieae of Dioscoreaceae (sensu APG 2016, or Thismiaceae of other authors). The genus is widely distributed mainly in the tropical and subtropical regions with a concentration of species in Southeast Asia (ca. 30 species) including the Malay Peninsula, Sumatra, Java, Borneo, Thailand and Vietnam. In last decade, many new taxa have been described from Southeast Asia (e.g. Larsen & Averyanov 2007, Chantanaorrapint 2008 2012, Tsukaya & Okada 2012, Dančák et al. 2013, Nuraliev et al. 2014 2015, Truong et al. 2014, Tsukaya et al. 2014, Chantanaorrapint & Sridith 2015, Hroneš et al. 2015, Chantanaorrapint et al. 2016, Sochor et al. 2017). Members of the genus are small mycoheterotrophic herbs with a highly reduced habit and usually grow among leaf litter in shady wet forests.

Abstract

A new species of the terrestrial orchid genus Nervilia is described and illustrated from material collected at several localities in the Greater Mekong region of Southeast Asia. The multi-flowered inflorescence bearing relatively large flowers with a pubescent lip, and the many-veined, cordate-reniform leaf blade that is held well above ground level, place Nervilia mekongensis in section Nervilia. Despite being superficially similar to N. aragoana, a widespread species of tropical Asia and Australasia, it is most closely affiliated to N. fordii, a species known from southern China and Thailand. It is distinguished by its stout inflorescence and lip that is broadest midway along the hypochile and which has acute, forward-projecting side-lobes and a short, ovate mid-lobe. A conservation assessment plus taxonomic notes are provided.

Keywords: Nervilieae, Epidendroideae, Orchidaceae, Monocots, Asia

Distribution:— We confirmed herbarium material of Nervilia mekongensis from eastern and northern Thailand, northern Laos, eastern Cambodia, and northern and southern Vietnam. Plants photographed by Naruemol Karnsunthad in Mae Ping National Park in Lamphun Province, northern Thailand, were also verified as belonging to this species (Fig. 1B).

Ecology:— At the type locality in eastern Thailand, Nervilia mekongensis grows in dry deciduous forest dominated by Shorea siamensis. In northern Thailand and Laos, it occurs in dry deciduous forest on limestone, and in Cambodia it is found in open deciduous forest, growing together with the terrestrial orchids Eulophia spectabilis (Dennst.) Suresh and Geodorum siamense Rolfe ex Downie. In Vietnam, it grows in open secondary scrub and grasslands at the edge of disturbed forest on eroded limestone ridges. It is known throughout an elevational range of 250–1,000 m.

Phenology:— Flowering April to June, in leaf from July until November. 

Etymology:— Named for the Mekong River, which flows through all four range countries and supports the enormous biodiversity of the region.

Vernacular name:— Thai: ว่านแผ่นดินเย็นแม่โขง (Wan phaen din yen mekong).

PHOTOS: P. KARAKET.  DOI: 10.1007/s12225-016-9614-0 

Summary

Four new species of Microchirita (C. B. Clarke) Yin Z. Wang are here described: Microchirita huppatatensis C. Puglisi and M. personata C. Puglisi, from Uthai Thani province, and M. hemratii C. Puglisi and M. lilacina C. Puglisi, from Tak province. Proposed conservation assessments are given for all species.

Key Words: Chirita, limestone, Tak, Uthai Thani

หยาดอุทัย | Microchirita personata C. Puglisi sp. nov.

Type: Thailand, Uthai Thani, Lan Sak, Huppatat Non Hunting Area, D. J. Middleton, C. Hemrat, P. Karaket, C. Puglisi & S. Suddee 5688 (holotype BKF; isotypes AAU, E, K, QBG, SING).

Habitat. Lithophyte, on bank over limestone rocks in secondary forest.

Conservation Status. Critically Endangered [CR B1ab(iii,iv)+B2ab(iii,iv)]. This species is only known from the type collection in the Huppatat Non Hunting Area, where only one, small population was observed. The limestone range there is only about 12 km2 in total and is subject to disturbance from tourism. There are no collections from the nearby Khao Pha Ra, and the area is surrounded by cultivated land.

Etymology. Named for the personate corolla mouth.

Notes. Microchirita personata is the most immediately recognisable of the four new species and arguably the most distinctive species in the genus. Its main diagnostic feature is the personate corolla, a unique occurrence in Microchirita. The small corolla is also remarkable, with the entire flower hardly reaching 1 cm in length and the upper two lobes strongly reduced. M. personata appears most similar to M. woodii D. J. Middleton & Triboun (2013: 15) and M. huppatatensis, both with a corolla primarily white and with a smaller upper lip and expanded and slightly raised lower lip. These species, however, have much larger and non-personate flowers.

บุหงาหุบป่าตาด | Microchirita huppatatensis C. Puglisi sp. nov.

Type: Thailand, Uthai Thani, Lan Sak, Huppatat Non Hunting Area, D. J. Middleton, C. Hemrat, P. Karaket, C. Puglisi & S. Suddee 5689 (holotype BKF).

Recognition. Very similar to Microchirita woodii, differing in the indumentum of the anthers, the smaller flower, the more prominent yellow ventral stripe, and the acuminate leaves.

Habitat. Lithophyte, on bank over limestone rocks in secondary forest.

Conservation Status. Critically Endangered [CR B1ab(iii,iv)+B2ab(iii,iv)]. This species is only known from the type collection growing in a mixed population with Microchirita personata. Therefore, the same justifications apply.

Etymology. The new species is named after the type locality.

Notes. Microchirita huppatatensis is most similar to M. woodii, a species only known from Nan province. Both species share a corolla colour pattern of mostly white with a yellow ventral stripe surrounded by purple-brownish spots. The two species, however, differ significantly in the size of the corolla (much larger in M. woodii), the leaf ratio (higher in M. huppatatensis), leaf apex (acute, not acuminate, in M. woodii), leaf size (much larger in M. woodii), and the basal inflorescence, which can be compound in M. woodii. In living material the following additional differences in the corolla are observed, but these, unfortunately, are not preserved in dry or rehydrated flowers. The overall mouth shape is depressed in M. woodii and apically compressed in M. huppatatensis; the yellow stripe that runs down the inner, ventral part of the corolla is strongly raised in M. huppatatensis and much less so in M. woodii, which also has the ventral part of the tube linear, not pouched.

ศรีเห็มรัตน์ | Microchirita hemratii C. Puglisi sp. nov.

 Type: Thailand, Tak, Mae Sot distr., Wat Tham Inthanin, D. J. Middleton, C. Hemrat, P. Karaket, C. Puglisi & S. Suddee 5775 (holotype BKF; isotypes E, SING).

Recognition. Similar to Microchirita suddeei D. J. Middleton & Triboun (2013: 18), M. lilacina and M. albiflora Middleton & Triboun (2013: 19), but is characterised by the combination of open corolla mouth (unlike M. suddeei and M. albiflora), ventral yellow stripe (unlike M. suddeei) and hairy anthers (unlike M. albiflora and M. lilacina).

Habitat. Lithophyte on limestone in mixed deciduous forest.conservation status. Endangered [EN B1ab(iii,iv)+B2ab(iii,iv)]. The known EOO of this species would qualify it for Critically Endangered but the collecting localities are in a limestone range much of which has so far not been explored and where it is also likely to occur. Even if it were to occur throughout this range its EOO would still qualify it as Endangered. Parts of this range, including some of the known localities, are outside protected areas and subject to disturbance from visitors, particularly at the religious sites.

Etymology. The species is named in honour of Chandee Hemrat, one of the collectors of the types of all of the new species.

Notes. See notes under Microchirita lilacina.

บุหงาอุ้มผาง | Microchirita lilacina C. Puglisi sp. nov.

Type: Thailand, Tak, Umphang, D. J. Middleton, C. Hemrat, P. Karaket, C. Puglisi & S. Suddee 5704 (holotype BKF; isotypes AAU, E, K, QBG, SING).

Recognition. Similar to Microchirita suddeei, M. albiflora and M. hemratii. Differs from M. suddeei in the glabrous anthers and the presence of a yellow stripe; differs from M. albiflora in the shape of the tube (trumpet shaped in M. albiflora and narrow at base and suddenly broadening into a campanulate upper tube in M. lilacina) and the size of the corolla lobes; and differs from M. hemratii in the glabrous anthers (densely hairy dorsally in M. hemratii).

Habitat. On limestone in dry and disturbed environments.

Conservation status. Endangered (EN B1ab(iii,iv)+B2 ab(iii,iv)). This species is known from disturbed roadside collections, with the exception of two collections in Doi Hua Mot Wildlife Sanctuary, over an area within the bounds of an EOO in the Endangered category. Its known localities are subject to disturbance.

Etymology. The plant is named after its pale lilac corolla.

Notes. Microchirita hemratii and M. lilacina belong to a group of species characterised by corolla colours ranging from pale lilac-white to blue. M. hemratii and M. lilacina have small corollas in comparison with most members of their group, which are also much darker in colour. The only species somewhat similar to them are M. suddeei, M. albiflora and M. karaketii D. J. Middleton & Triboun, all from Northern Thailand. M. karaketii is similar in the shape of the corolla tube, but differs in the colour pattern of the corolla, being white with a ventral yellow line and purple spots to either side of it. M. albiflora is pure white and differs from the other species in having its anthers free, a rare feature in Microchirita. M. suddeei is much closer to M. hemratii and M. lilacina, and the main difference is in the absence of the ventral yellow stripe in the flower, which is present in both the new species. Finally, one other important distinguishing feature between these closely related species is the indumentum dorsally on the anthers, which is present in M. suddeei and M. hemratii, reduced in M. karaketii and absent in M. lilacina and M. albiflora.

ABSTRACT

A new species, Paraboea maculata C.Puglisi, is described. It is compared to similar species and the habitat on granite rocks, unusual for the genus, is highlighted.

Keywords. Gesneriaceae, Paraboea, Thailand

Paraboea maculata C.Puglisi, sp. nov. Differs from other Paraboea species in the Paraboea martinii group, i.e. those with opposite leaves, campanulate corolla, twisted fruit and a terminal inflorescence, by the combination of a predominantly white and laterally compressed corolla, the purple spots at the base of the tube, the sticky glandular secretion on the bracts and calyx, and the winged petioles.

[Orchidology • 2013] Nervilia khaoyaica | ว่านแผ่นดินเย็นเขาใหญ่ • Studies in Asian Nervilia (Orchidaceae) III: N. khaoyaica, a new species (Section Linervia) from Khao Yai, Nakhon Ratchasima Province, eastern Thailand

ว่านแผ่นดินเย็นเขาใหญ่
Nervilia khaoyaica Suddee,Watthana & S.W. Gale

Summary

A new one-flowered species of Nervilia is described and illustrated from plants collected in Nakhon Ratchasima Province, eastern Thailand. The glabrous, angular leaf of Nervilia khaoyaica Suddee, Watthana & S. W. Gale affiliates it to the taxonomically difficult and widespread Nervilia adolphi – punctata species alliance of Section Linervia, but it is otherwise readily distinguished by its broad, oblong-obovate lip with a saccate base and obscure, rounded side lobes below the middle, and by the striking colouration of the disk.

 Keywords: Section Linervia, species alliance, taxonomy

มีการสำรวจพบพืชชนิดใหม่ของโลกในประเทศไทย  วงศ์กล้วยไม้ (Orchidaceae)  ให้ชื่อว่า Nervilia khaoyaica Suddee,Watthana & S.W. Gale  หรือ “ว่านแผ่นดินเย็นเขาใหญ่” เนื่องจากพบที่อุทยานแห่งชาติเขาใหญ่ จ.นครราชสีมา โดยขณะนี้ได้รับการยืนยันจากสวนพฤกษศาสตร์หลวงเมืองคิวประเทศอังกฤษ ซึ่งเป็นศูนย์กลางและแหล่งรวบรวมข้อมูลทางด้านวิชาการของพรรณไม้จากทั่วโลก  และได้รับการตีพิมพ์ในวารสารทางพฤษศาสตร์คิว บูลเลติน ( kew Bulletin) ของทางสวนพฤกษศาสตร์หลวงเมืองคิว  ฉบับล่าสุดคือฉบับที่ 68 ของปี 2556 แล้ว

นายสมราน สุดดี  นักวิทยาศาสตร์ชำนาญการพิเศษ สำนักหอพรรณไม้ วิจัยการอนุรักษ์ป่าไม้และพันธุ์พืช กรมอุทยานแห่งชาติสัตว์ป่าและพันธุ์พืช กระทรวงทรัพยากรธรรมชาติและสิ่งแวดล้อม กล่าวว่า สำหรับว่านแผ่นดินเย็นเขาใหญ่ นั้นจัดเป็นกล้วยไม้ดินชนิดหนึ่ง ชอบขึ้นในพื้นที่ที่มีความชุ่มชื้นสูงและเย็น จึงได้ชื่อว่าว่านแผ่นดินเย็น   แต่ชาวบ้านทั่วไปมักเรียกพืชชนิดว่าว่านพระฉิม สำหรับว่านแผ่นดินเย็นเขาใหญ่นั้น ขึ้นอยู่บนเขาที่มีความสูงจากระดับน้ำทะเลประมาณ  733 เมตร ความสูงของต้นตั้งแต่หัวใต้ดินถึงช่อดอกประมาณ 9 ซม.  ดอกมีกลีบเลี้ยงสีน้ำตาลอ่อนแกมเขียว ไปจนถึงน้ำตาลเข้มหรือน้ำตาลแดง 5 กลีบ กลีบปากมีแถบสีเขียวหรือบางดอกมีสีเหลืองตรงกลางกลีบ และมีเส้นและจุดสีม่วงกระจายอยู่รอบๆ กลีบดอก ออกดอกช่วงเดือน มี.ค. ที่สำคัญใบมีลักษณะพิเศษคือเป็นรูปหัวใจ ทรงเหลีี่ยม ยาว 4.8-6.7 ซม. กว้าง 5.5-6.8 ซม.  บางต้นออกใบเป็นสีม่วง บางต้นใบเป็นสีเขียว ซึ่งถือเป็นความผันแปรของพืชชนิดนี้  ใบและดอกออกคนละช่วงเวลาไม่พร้อมกัน

นายสมราน กล่าวอีกว่า ทั้งนี้ว่านแผ่นดินเย็นเขาใหญ่ ผู้พบคนแรกคือ นายณรงค์ จิระวัฒน์กวี นักวิจัยนกเงือกในพื้นที่อุทยานฯ เขาใหญ่ พบบริเวณเส้นทางไปยังน้ำตกผากล้วยไม้ เมื่อปี 2554 และได้นำภาพถ่ายมาสอบถาม จึงได้ลงพื้นที่เก็บตัวอย่างมาศึกษาและตรวจสอบร่วมกับ นายสันติ วัฒฐานะ นักวิชาการองค์การสวนพฤกษศาสตร์  (อสภ.) และ นาย เอส.ดับบลิว.เกล นักพฤกษศาตร์ ชาวฮ่องกง ใช้เวลาตรวจพิสูจน์ 2 ปี จึงได้รับการยืนยันว่าเป็นพืชชนิดใหม่ของโลก  ทั้งนี้สำหรับปริมาณที่พบนั้นไม่มาก พบขึ้นประปรายอยู่จุดเดียวบริเวณเส้นทางระหว่างน้ำตกผากล้วยไม้ไปยังน้ำตกเหวสุวัต อีกทั้งเรายังไม่ได้สำรวจทั่วบริเวณเขาใหญ่ สถานภาพตอนนี้จึงถือว่ามีความอ่อนไหวพอสมควร หากสภาพพื้นที่ป่ามีการเปลี่ยนแปลง ถูกทำลายก็อาจกระทบกับพืชชนิดนี้ได้

นายสมราน กล่าวด้วยว่า นอกจากนั้นยังมีพืชพันธุ์ใหม่ของโลกที่พบในปรเทศไทย และอยู่ระหว่างการยืนยันข้อมูลและตีพิมพ์ในวารสารพฤกษศาตร์ต่างประเทศอีก 4  คือ ว่านแผ่นดินเย็นอุ้มผาง พบที่ดอยหัวหมด อ.อุ้มผาง   จ.ตาก  เอื้องรังนกอุ้มผาง  เสี้ยวศักดิ์สุวรรณ และสาวสนมดงนาทาม  พบที่ดงนาทาม จ.อุบลราชธานี   ซึ่งเป็นสิ่งที่แสดงให้เห็นความหลากหลายทางของชนิดพันธุ์พืชของประเทศไทย
