Corybaspapillatus (Orchidaceae), a new orchid species from peninsular Thailand.

ABSTRACT: A new species, Corybaspapillatus, is described and illustrated from peninsular Thailand. The new species is easily recognized through a combination of the following characters: the purplish flower, the rounded apex of the dorsal sepal, the outer surface of dorsal sepal covered with irregular papillae in the upper half, the lateral sepals adnate laterally at the base to the connate petals, the V-shaped throat, the labellum bearing short hairs, dentate to erose labellum margins, and well-developed conical spurs. A key to the species of Corybas in Thailand is presented.

Bulbophyllumromklaoense (Orchidaceae), a new species from Thailand.

Project description:Bulbophyllumromklaoense (B.sect.Lemniscata) from northern Thailand is described and illustrated as a species new to science. It is most similar to B.muscarirubrum and B.triste, but differs by having inflorescences with only 4-6 reddish-brown flowers, falcate-subovate lateral sepals that are connate only in the upper half along the interior margins, petals with erose to fimbriate margins and a lip with long cilia in the distal half on the lower surface. A comparison with other similar species in the section, as well as notes on ecology, phenology, conservation assessment and a key to B.sect.Lemniscata in Thailand are also provided.

Schiedeella bajaverapacensis (Orchidaceae, Spiranthinae), a New Orchid Species from Guatemala.

Project description:Guatemala is recognized for its diverse and rich flora and fauna. It is estimated that over 1200 orchid species, classified in 223 genera, are known to occur in this rather small, yet megadiverse country. While studying the diversity of this plant group in the department of Baja Verapaz, we found individuals that clearly belonged to the genus Schiedeella, but whose features did not fit any previously known species. At that time, nine terrestrial taxon representatives were known to occur in Guatemala. We conducted the morphological analysis in accordance with the standard procedures of classical taxonomy. For phylogenetic reconstruction, 59 sequences of the ITS region and 48 of the trnL-trnF marker were applied. The topology of trees was obtained based on the Bayesian inference. Schiedeella bajaverapacensis was described and illustrated based on morphological evidence, and its taxonomic position was confirmed by phylogenetic analyses. The new entity is the 10th Schiedeella representative known from Guatemala.

New species and new records of Artabotrys (Annonaceae) from peninsular Thailand.

Project description:Two new species of Artabotrys (Annonaceae) are described from peninsular Thailand. Artabotrys longipetalus J.Chen & Eiadthong, sp. nov., is unique among Artabotrys species in Thailand in having linear petals, relatively long flower pedicels and sessile monocarps. Artabotrys insurae J.Chen & Eiadthong, sp. nov., resembles Artabotrys uniflorus (Griff.) Craib, but can be distinguished by its oblique leaf base, flat petal blades, apiculate anther connective apex and the presence of a monocarp stipe. In addition, two new records for the Flora of Thailand are reported, viz. Artabotrys crassifolius Hook.f. & Thomson and Artabotrys pleurocarpus Maingay ex Hook.f. & Thomson; both species are so far only known from peninsular Thailand. A key to the 20 species of Artabotrys in Thailand is provided.

Mitrephoramonocarpa (Annonaceae): a new species from Surat Thani Province, Peninsular Thailand.

Project description:A new species, Mitrephoramonocarpa R.M.K.Saunders & Chalermglin, sp. nov. (Annonaceae), is described from Surat Thani Province in Peninsular Thailand. It resembles two other species, M.alba Ridl. and M.keithii Ridl., with which it is broadly sympatric, but can be distinguished by its solitary flowers (not borne in thyrsoid inflorescences as in most other Mitrephora species), single carpel per flower (and hence single monocarp per fruit) and the lack of a monocarp stipe. A key to the nine Mitrephora species in Thailand is provided.

Goniothalamusroseipetalus and G.sukhirinensis (Annonaceae): Two new species from Peninsular Thailand.

Project description:Two new Goniothalamus species (Annonaceae), G.roseipetalus sp. nov. and G.sukhirinensis sp. nov., are described from the southern limits of Peninsular Thailand (Narathiwat and Yala Provinces). Both new species resemble G.macrophyllus, G.scortechinii and G.uvarioides. The addition of these two new species brings the total number of Goniothalamus species in Thailand to 27. Separate identification keys are provided for flowering and fruiting specimens of the Thai species.

Pachygenium laurense (Orchidaceae, Spiranthinae), a new orchid species from Argentina-morphological evidence and phylogenetic reconstruction.

Project description:BackgroundPachygenium embraces a group of terrestrial species formerly placed in Pelexia sensu lato. The genus currently comprises some 60 species, most of which are known from the southern parts of Brazil and Paraguay, with few species distributed in the Andean countries-only four species have been recorded from Argentina so far. In Jujuy Province, Argentina a new species of Pachygenium was found during our fieldwork. The aim of this article was to provide morphological and molecular evidence for its membership in this genus.MethodsMaterials from specimens were collected in the field and examined by classical taxonomic and molecular biological techniques, e.g., PCR and sequencing DNA. Phylogenetic reconstruction was performed by maximum-likelihood and Bayesian inference.ResultsPachygenium laurense from Argentina is described and illustrated based on morphological evidence and its taxonomic position was confirmed by phylogenetic analyses. A new combination for Pachygenium gutturosa is also proposed. A key for identification is provided for the Pachygenium species occurring in Argentina.ConclusionPachygenium laurense is the fifth species of the genus recorded from Argentina.

The Gastrodia menghaiensis (Orchidaceae) genome provides new insights of orchid mycorrhizal interactions.

Project description:BackgroundTo illustrate the molecular mechanism of mycoheterotrophic interactions between orchids and fungi, we assembled chromosome-level reference genome of Gastrodia menghaiensis (Orchidaceae) and analyzed the genomes of two species of Gastrodia.ResultsOur analyses indicated that the genomes of Gastrodia are globally diminished in comparison to autotrophic orchids, even compared to Cuscuta (a plant parasite). Genes involved in arbuscular mycorrhizae colonization were found in genomes of Gastrodia, and many of the genes involved biological interaction between Gatrodia and symbiotic microbionts are more numerous than in photosynthetic orchids. The highly expressed genes for fatty acid and ammonium root transporters suggest that fungi receive material from orchids, although most raw materials flow from the fungi. Many nuclear genes (e.g. biosynthesis of aromatic amino acid L-tryptophan) supporting plastid functions are expanded compared to photosynthetic orchids, an indication of the importance of plastids even in totally mycoheterotrophic species.ConclusionGastrodia menghaiensis has the smallest proteome thus far among angiosperms. Many of the genes involved biological interaction between Gatrodia and symbiotic microbionts are more numerous than in photosynthetic orchids.

Thuniopsis: A New Orchid Genus and Phylogeny of the Tribe Arethuseae (Orchidaceae).

Project description:An investigation of a questionable orchid led to the discovery of a new genus and species Thuniopsis cleistogama, endemic to Yunnan province, China. It is characterized by having a subglobose corm, a spike-like (racemose) inflorescence, half opened and spurless flowers, a collar-shaped stigma and subglobose capsules. Based on DNA sequence data from three gene regions (nuclear ribosomal ITS, chloroplast matK and trnL), we investigated its phylogenetic position within the tribe Arethuseae. Phylogenies using maximum likelihood and Bayesian inference support the recognition of Thuniopsis as a distinct genus, and suggest its close relationship to the genera Bletilla, Dilochia, and Thunia. The new genus is circumscribed and a description and illustrations of the new species are provided. The phylogenetic relationships among the genera in Arethuseae are accessed. Moreover, our phylogeny also shed light on the phylogenetic positions of several genera which, to date, remain uncertain.
