Abstract

Alysicarpus littoralis Satthaphorn & Leerat. (Fabaceae, Desmodieae), a species confined to Samui Island, Surat Thani province, southern Thailand, is described and illustrated as a species new to science. Initially identified as A. vaginalis (L.) DC., the re-examination of morphological characters revealed distinctions of A. littoralis such as the length of inflorescence internode, length of calyx lobes, the colour of corolla and the type of pods at maturity. The newly proposed species is sometimes similar to A. monilifer (L.) DC. And A. ovalifolius (Schumach.) J. Léonard as it exhibits moniliform pods and lax inflorescence, respectively. The conservation status of the new species is assessed as Critically Endangered (CR, B2(bii+ciii)) following IUCN conservation guidelines since populations are surrounded by human disturbances. A morphological description, line drawing and updated key to species of Alysicarpus in Thailand are presented.

 Type: Thailand, Surat Thani, Ko Samui, Bo Phut, Ban Bo Phut, 20 m alt., 3 Jan. 2021, Leeratiwong 21-1634 (holotype PSU!; isotypes BKF!, KKU!). Figs. 1–2. 

Diagnosis.— Alysicarpus littoralis superficially resembles A. vaginalis in its herbaceous habit, unifoliolate leaves, pseudoracemose inflorescence, valvate calyx and erect loment pods (Fig. 3). However, A. littoralis is distinguishable by longer petiolules (1–1.5 mm long vs ca. 0.3 mm long in A. vaginalis), longer inflorescence internodes (8–12 mm long and lax-flowered vs 2–5 mm long and compact-flowered), longer calyx lobes (3–5 mm long vs 2.3–3 mm long), two-tone-coloured corolla (orangish-yellow standard but pink wings vs monotone-coloured-pink to purple in all petals) and moniliform pods with barrel shaped articles at maturity (vs terete pods with cylindrical articles).

Etymology.— The specific epithet refers to its habitat which can be found in coastal areas.

Vernacular.— Thua lisong na samui (ถั่วลิสงนาสมุย).

Abstract

During botanical expeditions focused on the study of Annonaceae in Thailand, specimens resembling Friesodielsia glauca were collected from the lower part of peninsular Thailand but were believed to differ from that species in vegetative, flower, and fruit characters. A morphological investigation of the new specimens and species complex was conducted. Specimens (including types of F. glauca and similar species collected from Thailand and adjacent regions) were examined in the following herbaria: A, BK, BM, BKF, E, K, KEP, KKU, L, PSU, QBG, SING, and US. As a consequence, the new species Friesodielsia parvimitra, endemic to peninsular Thailand, is described and illustrated. The conservation status of the new species was provisionally assessed as Critically Endangered (CR, B2ab(iii)) following the IUCN’s guidelines. In addition, F. argentea, previously regarded F. glauca, is reinstated here as a distinct species based on several morphological differences and is reported as a new record from Thailand. Photographs, line drawings, and a revised key to F. glauca and similar species are presented.

Friesodielsia parvimitra Satthaphorn & Leerat., sp. nov.

Diagnosis: Friesodielsia parvimitra superficially resembles F. glauca in having inner petals shorter than half of the length of its outer petals, but differs in its non-glaucous lower leaf surface, much shorter flower pedicels (12–16 mm long vs. 20–40 mm long in F. glauca), shorter bracts (0.5–0.8 vs. 0.9–1.7 mm long), reduplicate sepals 2–3 mm long (vs. non-reduplicate sepals 4.0–5.5 mm long), and inner petals 4–5 mm long with puberulous appressed hairs on the outside surface (vs. 7–10 mm long with a glabrous outside surface).

 

Etymology: The specific epithet pertains to the inner petals that are connivent and short (less than 5 mm long), resembling a headdress.

Abstract

Derris rubricosta Boonprajan & Sirich., sp. nov., a new species of the genus Derris Lour. (Fabaceae) was discovered in Peninsular Thailand. The overall morphology demonstrates that the species most resembles D. pubipetala. Nevertheless, the species has several autapomorphies differentiating it from other Derris species, e.g., the presence of reddish midribs of the mature leaflets, sparsely hairy stamen filaments, prominent hairs at the base of the anthers, and presence of glandular trichomes along the leaflet midrib. Additionally, HPLC fingerprints of this species showed a distinction from D. pubipetala by the absence of phytochemical compound peaks after 13 min. Retention Time (RT). Results from molecular phylogenetic analyses also strongly supported the taxonomic status as a new species.

 Derris rubricosta Boonprajan & Sirich., sp. nov.

 

Diagnosis: The species has several autapomorphies distinguishing it from other Derris species. It is the only species that has reddish midribs on the lower surface of mature leaflets. Its style is sericeous at the base and gradually becomes glabrous apically (vs. thinly hairy at the base and mostly glabrous throughout in other Derris species). Derris rubricosta has prominent hairs below the anthers (vs. glabrous anthers in all other Derris species). It is morphologically similar to D. pubipetala Miq., but differs by its leaflet midrib colour (reddish vs. green), number of leaflets or leaf (9–11 vs. 5–9), colour of its corolla (pale pink to pink vs. white), wing petal margin (straight vs. revolute), stamen filament indumentum (sparsely hairy vs. glabrous), indumentum presence below the anthers (present vs. absent), floral disc shape (indistinct to more-or-less 10-lobed vs. annular).

Etymology: The specific epithet refers to the striking reddish colour of the midrib of the mature leaflets which has never been found in other species of Derris.

Vernacular names: “Khruea lai leeratiwong” (เครือไหลลีรติวงศ์) means “Leeratiwong’s Derris”, in Thai, in honor of Associate Professor Dr. Charan Leeratiwong, who discovered and collected the type specimens.

Distribution: Peninsular Thailand: Songkhla (Rattaphum district, Sadao district) (Fig. 4). Estimated population of more than 2,500 mature individuals were found during field survey between 2019 and 2022 in its type locality and nearby areas.

Abstract

Three new Mitrephora species (Annonaceae), M. langsuanensis sp. nov., M. sirindhorniae sp. nov. and M. sukhothaiensis sp. nov., are described from Thailand. Mitrephora langsuanensis resembles M. macclurei, but its leaves have more secondary veins, and its flowers have more carpels, with yellow-and-pink striped outer petals with a margin that becomes undulate with age. Mitrephora sirindhorniae resembles M. tomentosa, but has larger sepals and petals, longer flowering pedicels, and shorter monocarp stipes, with monocarps that have a longitudinal ridge. Mitrephora sukhothaiensis is distinct from its Thai congeners in having outer petals that reflex at maturity and inner petals with a pair of appendages on the margin adaxially. The addition of these three new taxa raises the total number of Mitrephora species in Thailand to 14. An identification key for Thai species is provided.

Friesodielsia brevistipitata Leerat., sp. nov.

Friesodielsia brevistipitata is most similar to F. desmoides (Craib) Steenis and F. songkhlaensis Leerat. It differs from F. desmoides in having appressed rather than erect hairs on the abaxial leaf surface, sepals 5–10 mm versus 4–5 mm long, outer petals 35–60 mm versus (19–)27–31 mm long and obtuse versus acute at the apex, and monocarp stipes 3–5 mm versus 7–10.5 mm long. From F.   songkhlaensis it may be distinguished by the shorter sepals that are rounded to an obtuse or slightly acute apex and again by the short monocarp stipes.

Etymology.— Named for the short stipes of the monocarps, among the shortest in the entire genus.

Vernacular.— Sa lao (ส่าเหล้า)(Krabi).

Friesodielsia khaoluangensis Leerat. & Aongyong, sp. nov.

Friesodielsia khaoluangensis resembles F. alpina (J.Sinclair) Steenis and F. borneensis (Miq.) Steenis in its narrow flowers and narrow leaves. From F. alpina it differs in the twigs and leaves appressed-pubescent rather than glabrous, larger leaves (13–22 × 3.8–7.5 cm versus 8.5–13 × 3–4 cm) but with only 9–12 secondary veins per side versus 12–14 per side, the pedicels ca 10 mm long versus 25–27 mm long, and the outer petals linear-lanceolate, 23–25 mm long, and appressed-pubescent versus lanceolate, ca 15 mm long, and glabrous. From F. borneensis it differs in the leaves not glaucous abaxially and with petioles 8–17 mm long instead of glaucous abaxially with petioles 4.5–8 mm long, the pedicellar bract lanceolate rather than linear, and petals 23–25 mm long rather than 52–59 mm long.

Etymology.— The species is named for the type locality.

Vernacular.— Bu nga khao luang (บุหงาเขาหลวง) (General), 

sao yut (สาวหยุด) (Nakhon Si Thammarat).

Friesodielsia  longipetala Leerat. & Chalermglin, sp. nov.

Friesodielsia longipetala is distinguished from F.  phanganensis  and F.  songkhlaensis  by its sub-coriaceous to coriaceous leaves, outer petals (50–)80–140 mm long, inner petals (11–)15–25 mm long, generally longer pedicels (up to 12 mm long), and monocarps only sparsely pubescent.

Etymology.— Named for the greater length of both the outer and inner petals compared with those of its congeners.

Vernacular.— Bu nga taeng ngan (บุหงาแต่งงาน)(General), 

sao yut (สาวหยุด)(Satun).

Friesodielsia  macrosepala Leerat. & Aongyong, sp. nov.

Friesodielsia macrosepala is similar to F. unonifolia but differs in having twigs covered by persistent mixed spreading and appressed hairs, sepals (7–)11–17 × (5–)9–11 mm, and outer petals 50–80 × 11–22 (–32) mm, with a length:width ratio ofca 4:1. Friesodielsia unonifolia, in contrast, has twigs initially covered with appressed hairs but soon glabrate, sepals 7–9 × 5.5–7 mm long, and outer petals 18–35 (–40) × 9.5–12 mm with a length:width ratio of ca 2.5:1.

Etymology.— The sepals are among the largest in the entire genus. 

Vernacular.— Bu nga sawitri (บุหงาสาวิตรี)(Nakhon Si Thammarat), 

sao yut (สาวหยุด)(Nakhon Si Thammarat)

Friesodielsia phanganensis Leerat., sp. nov.

Friesodielsia phanganensis is distinguished from F. longipetala by the chartaceous leaves, oblanceolate to elliptic-oblanceolate outer petals 50–70 mm long, inner petals 11–15 mm long, and monocarps densely pubescent with shorter stipes 3–5 mm long. 

Etymology.— The species is named for the type locality.

Vernacular.— Bu nga soeang phangan (บุหงาเซิงพะงัน)(General).

Friesodielsia songkhlaensis Leerat., sp. nov.

Friesodielsia songkhlaensis is distinguished from F. longipetala by the chartaceous leaves, pedicels 3–5 mm long with the bract exceeding the pedicel inlength, sepals tapering to a blunt-acuminate apex, outerpetals 6–12 mm wide, inner petals 8–10 mm long, and more densely pubescent monocarps.

Etymology.— Named for the Thai province in which it occurs.

Vernacular.— Bu nga soeng songkhla (บุหงาเซิงสงขลา)(General).

Polyalthia heliopetala most closely resembles P. oblonga and P. motleyana. Polyalthia taweensis most closely resembles P. obliqua. Polyalthia pumila is newly reported for Thailand from a single locality; the species was previously known only from two localities in Peninsular Malaysia and has not been re-collected in over 100 years.
