เทพมาศ |  Flemingia sirindhorniae Mattapha, Chantar. & Suddee 


Abstract 
     A new species, Flemingia sirindhorniae Mattapha, Chantar. & Suddee, from Tak province, Thailand, is described and illustrated, and its affinities are discussed. It is a very rare species in Thailand and its conservation status is assessed here as Data Deficient (DD).

KEYWORDS: Doi Hua Mot, IUCN Red List, new species




Flemingia sirindhorniae Mattapha, Chantar. & Suddee, sp. nov.

 Type: Thailand, Tak province, Umphang district ...
  (holotype BKF; isotypes BK, BM, E, K, KKU, L, MBK, P, QBG).


This species stands out from F. involucrata Benth. and F. vestita Baker by its 1–3-digitately compound leaves, the presence of basal callosities on the standard, exserted corolla which is longer than the calyx, and by having a tubular floral disc.

N. Muangyen, et al. 2015. || QSBG.or.th

ABSTRACT

Rhynchanthus bluthianus, from Mae Hong Son Province, is newly recorded for Thailand.

Keywords: Rhynchanthus, Zingiberaceae, Mae Hong Son, Thailand


Thailand.— NORTHERN: Mae Hong Son (Sob Moei).

Distribution.— Myanmar.

Ecology.— Epiphyte on tree trunk, montain forest, ca. 1,200 m alt.

Notes.— Two species of Rhynchanthus in Thailand belong to the few-flowered group. The major difference of both species is colour of flower. Rhynchanthus bluthianus is distinguishable from R. longiflorus by its pinkish white corolla and filament (vs. yellow corolla and filament). Type specimen of R. bluthianus is assumed (from the first publication) to be deposited in the Botanischer Garten und Botanisches Museum BerlinDahlem (B) and may be lost in the fire of the museum in 1943 (Dr. Robert Vogt, curator, pers. comm.).

'middletonii' named in honour of Dr D. J. Middleton, a plant taxonomist from the Royal Botanic Garden Edinburgh and the leader of the Thai Gesneriaceae research team.

Proposed IUCN conservation assessment.— Critically Endangered (CR B1ab(iii)). This species is only known from the type locality, which is a small limestone outcrop right beside the road on the boundary of Doi Phu Kha National Park and with extensive agricultural areas beyond. The basal area of the outcrop shows considerable disturbance. There are estimated to be fewer than 500 plants in the population.

[Orchidology • 2013] Five Species of Liparis (Orchidaceae) newly recorded for Thailand




ABSTRACT.
During work on a forthcoming new revision of Liparis in Thailand, five new national records were discovered, and  details on the Thai occurrences are reported in this paper.

Three of the newly recorded species are terrestrials that only produce leaves in the rainy season. Thus, (1) L. acutissima Rchb.f. (also known from Cambodia, Laos and Vietnam) is reported from Phu Wua Wildlife Sanctuary, province of Bueng Kan; (2) L. sootenzanensis Fukuy. (also known from Taiwan and Vietnam), is reported from Phu Hin Rong Kla National Park, province of Phitsanulok; and (3) L. stenoglossa C.S.P.Parish & Rchb.f. (previously considered endemic to Myanmar) is reported from Wat Tham Pha Sawan, Nong Hin, province of Loei.

The two remaining species are epiphytes that bear leaves all the year round. Thus, (4) L. elegans Lindl. widespread in Malesia) is reported from Khao Sok National Park in province of Surat Thani and from Khao Chet Yot in province of Trang; and (5) L. vestita Rchb.f. (previously known from India only) is reported from Amphoe Rong Kwang in province of Phrae and from two parts of Khao Yai National Park (situated in the provinces of Nakhon Nayok and Prachin Buri, respectively).

The newly recorded species are illustrated by colour photos, and morphological descriptions based on Thai material are provided together with lists of synonyms and supplementary references to the literature. The name L. elegans Lindl. is lectotypified.
