Bulbophyllum putaoensis (Orchidaceae: Epidendroideae; Malaxideae), a newspecies from Kachin State, Myanmar

   The orchid flora of Myanmar is highly diverse but as yet poorly known in the continental Asia, which is largely a result of periods of past instability and political isolation of the country. Also the remoteness of many orchid-rich areas and
the difficulties of investigation in rugged terrain have also played a role (Ormerod & Kumar, 2003; Kurzweil & Lwin,2014). According to recent estimates about 800 orchid species are distributed in Myanmar (Kurzweil & Lwin, 2014), which were probably underestimated. Many new distribution records and new species have been published in the last few years(Ormerod, 2002, 2006, 2012; Ormerod & Kumar, 2003, 2008; Ormerod & Wood, 2010; Nyunt, 2006; Kurzweil et al., 2010;Kurzweil & Lwin, 2012a,b; Tanaka et al. 2011).

   
   The genus Bulbophyllum Thouars (1822: 3) is among the largest genus of Orchidaceae, including more than 2200 species and widely distributed from tropical America, Africa, Madagascar, and mainland Asia to Australasia (Pridgeon et al. 2014). There are several centers of species diversity, including Madagascar (200 species), New Guinea (600 species),and continental Asia (400 species). Myanmar is also one of the diversity centers, contains about 109 species of this genus
(Govaerts et al., 2016). During our field expeditions in the Hponkanrazi Wildlife Sanctuary, Northern Myanmar, carried out by the Xishuangbanna Tropical Botanical Garden, CAS in cooperation with the Forest Department, Union of Myanmar Ministry of Forestry, one unusual species of Bulbophyllum had been discovered. After undertaking a comprehensive literatures and herbarium specimen review, it was identified as a new species and described blow.
