Aphyllorchis montana (Orchidaceae): A new record to the flora of Bhutan

Abstract

Two Aphyllorchis species are described in the Orchids of Bhutan. During recent floristic exploration, specimens of Aphyllorchis Bl. were collected from the warm broadleaved and subtropical forests of Mongar and Wangdue Dzongkhags. The specimens were identified as Aphyllorchis montana Rchb.f. which is a new record to the flora of Bhutan and is described and illustrated. A. montana can be distinguished from A. alpina by slender stem bearing up to 15 flowers on the inflorescence, flowers less than 1 cm long and ovary less than 3 mm wide. Detailed descriptions, phenology, habitat, conservation status, distribution, taxonomic notes and photographic illustration are provided. The IUCN status of this species is assessed as Data Deficient.
