A new species of Lepanthopsis is described and illustrated based on Peruvian material. Lepanthopsis bennettii is similar to L. dewildei from which it differs by long-connate lateral sepals, broadly
Taxonomic study of Polystachya Hook. (Orchidaceae) from Asia
In Asia, three species of Polystachya (Orchidaceae) are recognized, based on detailed morphological studies. They occur in southern Asia, from Tamil Nadu State in southern India and Yunnan Province
Phylogenetic Placement and Taxonomy of the Genus Hederorkis (Orchidaceae)
Three plastid regions, matK, rpl32-trnL and rpl16 intron and the ITS1-5.8S-ITS2 nuclear ribosomal DNA were used to demonstrate a phylogenetic placement of the genus Hederorkis (Orchidaceae) for the
New species of Sobralia section Abbreviatae Brieger (Orchidaceae) from Colombia. A morphological and molecular evidence
The analyses of the ITS and matK reveal close relationship between the new species and Sobralia klotzscheana, however, S. vallecaucana can be easily distinguished by its large leaves compared to its very short stem, leaves and leaves’ sheaths strongly hispid underside and lip with two basal ridges and without thickening along its central nerves.
