Abstract

Based on the molecular phylogenetic analyses of six plastid DNA regions (matK and rbcL exons; trnL intron; atpB-rbcL, psbA-trnH and trnL-trnF intergenic spacers) and including 57 samples of Pseuduvaria, as well as thorough morphological studies, Pseuduvaria sirindhorniana (Annonaceae, Miliuseae) is described and illustrated here as a new species from Narathiwat, southern Thailand. The new species belongs to a major clade that also includes P. fragrans, P. gardneri, P. glossopetala, P. kwangtungensis, P. multiovulata and P. phuyensis. Pseuduvaria sirindhorniana is morphologically most similar to P. glossopetala, but differs by having basally connate (vs. free) sepals, larger petals, elliptic-ovate (vs. obovate) outer petals, inner petals that are only connivent at the apex (vs. connivent from the base to ± the midpoint and at the apex), with openings formed from the base (vs. openings formed from ± the midpoint). Pseuduvaria kwangtungensis turns out to be a putative sister of the new species, but the two are morphologically dissimilar in several traits, such as leaf base, inner petal appearance and glands on the inner side of the inner petals.

Abstract  

A new species, Taeniophyllum wrightmyoensis (Orchidaceae) is described from the Andaman and Nicobar Islands, India. The new species resembles T. hasseltii and T. pusillum, but is distinct from both in having mostly terete free hanging roots (versus roots flat, appressed to the substratum), bracts lax (versus bracts close in T. pusillum), lip without any cushions (versus lip with convex cushions in T. hasseltii) and a conical spur (versus globose spur in T. pusillum). In addition, a review of other species of the genus Taeniophyllum reported from the Andaman and Nicobar Islands is provided with an identification key.

Taeniophyllum wrightmyoensis Alappatt, sp. nov.

This species is similar to Taeniophyllum hasseltii Rchb.f. and T. pusillum (Willd.) Seidenf. & Ormerod in having free sepals and petals, distichous bracts, fleshy lip and short anther-beak, but differs from them by its mostly free hanging terete roots and a few roots semi-terete when appressed to substratum (vs. roots flat, appressed to the substratum), bracts lax (vs. close in T. pusillum), comparatively smaller flowers (c. 3 mm across), not opening widely (vs. large flowers, 5–5.5 mm across, opening widely), lip blade without convex cushions (vs. with convex cushions in T. hasseltii), spur conical, being longer than broad (vs. globose, as long as broad in T. pusillum). 

Etymology. The specific epithet refers to the collections from Wrightmyo where the species was discovered.

DOI: doi.org/10.3767/blumea.2026.70.01.02

 Abstract 

We here describe Costus maasiorum, a new species from western Ecuador. This new species shares morphological similarities with Costus macrostrobilus, but differs in having plicate leaves, erect and triangular bract appendages, and semi-tubular elongate flowers. A phylogeny based on 5.9+ million single nucleotide polymorphisms (SNPs) strongly supports a sister relationship between C. maasiorum and C. macrostrobilus. Additional taxonomic sampling in subsequent analyses indicates a close relationship with C. gibbosus and C. antioquiensis. A comprehensive taxonomic description, including detailed photographs and information about the habitat and ecology of the new species are provided. A preliminary conservation status is recommended as Least Concern (LC).

Costus maasiorum D.Skinner, J.L.Clark, & C.D.Specht, sp. nov.

 Costus maasiorum sp. nov. can be recognized by its plicate leaves, often dark purple underneath, the presence of appendaged bracts with the appendages being erect and triangular in shape, and the primarily yellow flower with the labellum presenting as a narrow, elongate floral tube. The overall morphology of the plant is similar to that of Costus macrostrobilus, but the species differs in having a more tubular labellum, plicate leaves (non-plicate or flat leaves in C. macrostrobilus) and in the shape of the bract appendages that are concave and somewhat pungent (ending in a stiff, sharp point in C. macrostrobilus). 

Etymology — Costus maasiorum is named in honour of the botanical couple Professor Paul J.M. Maas and Hiltje Maas-van de Kamer and the contribution of this couple to systematic and taxonomic work within the Costaceae. It was Dr. Paul Maas who visited Bilsa in 1997 and first noted this species as undescribed. Paul began working on Costaceae during his PhD in which he completed two monographs on New World Costoideae for Flora Neotropica, establishing himself as the expert on this and other families of Neotropical Zingiberales. The two Flora Neotropica volumes, which included revisions of the Costoideae, provided species level descriptions and detailed understanding of taxonomic limits, biogeographic distributions, morphological variation, and relationships among species of Costaceae that still stand today, often being confirmed by subsequent DNA-based phylogenetic studies. Paul’s observations of differences between closely related species and awareness of variation noted in living plants and in herbarium specimens enabled and inspired decades of research on this interesting and charismatic tropical family. ...

Abstract 

We present a taxonomic revision of the genus Disporum in Thailand based on Thai specimens including descriptions of the genus and species, a key to the species, illustrations and lectotypifications. The dorsifixed anther attachment is a new character for the genus. There is a total of six species in Thailand, including the four new species described here, namely D. chiangdaoense, D. dorsifixerum, D. phuhinrongklaensis and D. scabridum, and two well-known species D. calcaratum and D. cantoniense. Anatomical and pollen morphological characters can be used for species diagnoses and they strongly support the morphological recognition of the four new species. New lectotypifications of synonyms are provided for D. wallichii, Uvularia calcarata and U. hamiltoniana.

Abstract 

Sophora phulangkaensis is illustrated and newly described here. The species shows similarities with its congener, S. exigua, by having an obovate terminal leaflet and up to 15 leaflets but differs in the floral parts. A morphological comparison between the two species is provided along with a discussion. The phylogenetic placement of the new species is presented and discussed based on molecular evidence by nuclear (ITS) and chloroplast markers (matK). The results suggest that the new species is nested into sect. Rubriflorae, which includes S. exigua and S. huamotensis. The circumscription of sect. Rubriflorae is expanded after being redefined by our findings. In addition, the updated key to species of the genus Sophora for the Flora of Thailand is given based on recent specimen observations. Additionally, lectotypes for S. exigua, S. tonkinensis, and S. violacea var. pilosa are designated.

Abstract 

Schoenorchis kembangleutik Yudistira & Mustaqim described here as new to science is an orchid species currently considered endemic to West Java. It is similar to S. pachyachris (J.J.Sm.) J.J.Sm. from Sumatra and Java but differs in having flowers with midlobe of labellum orbicular (vs oblong) with horizontal and rounded (vs pointing upwards and tapering to a point) apex, the labellum side lobes white, uncinate and retrorse at the apex (vs yellow, straight and erect at apex), and in having shorter spurs with straight base (2 vs 4 mm long, with geniculate base). A morphological description, notes on distribution, habitat and ecology, an illustration, photographs and a key to the five species of Schoenorchis of Java are provided.
