Abstract

The paper provides a taxonomic assessment of Bulbophyllum section Racemosae in Vietnam, accompanied by an identification key for all species currently recognized in the country. Information on type specimens, distribution, habitat and phenology (when available), as well as relevant taxonomic notes are presented for each accepted species, accompanied by plates with analytical photos. Bulbophyllum minhquanii is described as new to science, and B. albidostylidium (identified earlier as B. putii) is reported as a new national record. In total, 14 species of B. sect. Racemosae, of which five are endemic, are documented for Vietnam based on previous and current studies. The occurrences of B. macrocoleum and B. morphologorum in Vietnam remain uncertain and require verification by additional collections.

Abstract

We have described and illustrated a new species, Bulbophyllum yunxiaoense (Malaxideae, Epidendroideae, Orchidaceae), from Fujian Province in southeast China. The size and overall floral morphology of the new species are similar to those of Bulbophyllum pingtungense, a species endemic to Taiwan Island on the southeast coast of China and its closest relative according to a cladistic analysis of nuclear (ITS) and plastid (matK, trnL-F, and atpI-atpH) DNA sequences. However, B. yunxiaoense is distinguishable from B. pingtungense by flower colour, shorter scape, and longer lateral sepal.

Abstract

A new species of Bulbophyllum from section Lepidorhiza, B. abuniorum Saputra & Schuit., is described based on specimens from the Bird’s Head Peninsula, New Guinea. A detailed morphological description and diagnosis, information on distribution and ecology, and a preliminary conservation assessment are provided. A key to the species of Bulbophyllum section Lepidorhiza in New Guinea is also presented.

Keywords: Abun Tribe, Pegunungan Tambrauw, West Papua, endemic, indentification key

Bulbophyllum abuniorum Saputra & Schuit., sp. nov.

Diagnosis: Bulbophyllum abuniorum is similar to Bulbophyllum levyae Garay, Hamer & Siegerist (1995:176) especially in the shape of sepals and petals, the relatively long lip, and in the several simultaneously opening flowers (flowers usually opening one at a time in other species of sect. Lepidorhiza), but differs in having a slightly clawed lip at the base (vs. not clawed in B. levyae), densely irregular conical-subulate teeth all over the adaxial surface of the lip (vs. lip with papillae in the middle, smooth elsewhere), margin of lip laciniate basally, strongly serrate centrally, and crenate apically (vs. margin entire throughout).

Bulbophyllum dresslerianum Z. D. Han & H. Wang sp. nov.  

Diagnosis: Bulbophyllum dresslerianum is similar to B. dickasonii, B. kanburiense, B. rugosisepalum, and B. tripudiansin terms of morphological structure of flowers. This new species can be distinguished from B. rugosisepalum by dorsal sepal ovate to narrowly ovate, lateral sepals absent rugose-papillae, and the margins and adaxial side of epichile with sparely short glandular hairs. It can be distinguished from B. tripudians with the epichile of lip with globular papillae. In addition, the new species can be distinguished from B. dickasonii and B. kanburiense with the margins of dorsal sepals irregularly fimbriated, the petal ovate-lanceolated and the margins of petal fimbriated.

Etymology: The species is named for the late Robert Louis Dressler (1927—2019), an authority on the taxonomy of Neotropical Epidendroideae (including the Malaxideae) and his contributions to the evolutionary ecology of the Orchidaceae.

Abstract

Bulbophyllum trongquyetii is described as new for science from Vietnam. Detailed morphological description, illustration, data on distribution, and phenology are provided. Described species resembles B. nipondhii but differs in the bigger size of plant, longer inflorescence, and uniform yellow or reddish-orange flowers. It can be also compared with B. thaiorum and B. farreri but easily distinguished by the bigger size of plant and flowers, as well as smooth or sparsely papillose lateral sepals.
