Abstract

SALAZAR, Gerardo A.. Two additions to the Mexican orchid flora. Rev. Mex. Biodiv. [online]. 2013, vol.84, n.1, pp.378-380. ISSN 2007-8706.  https://doi.org/10.7550/rmb.26896.

Two species of Orchidaceae are recorded here for the first time in Mexico, namely Cryptarrhena guatemalensis and Domingoa gemma. Cryptarrhena guatemalensis is widespread in the Neotropics and can be distinguished from C. lunata, the only other species of the genus, by possessing pseudobulbs and narrowly triangular, attenuate apical labellum lobules. Domingoa gemma, previously known only from Guatemala and El Salvador, differs from the similar D. purpurea in the smooth, linear-lanceolate leaves and labellum lacking a prominent sac at the base. Both species are known in Mexico from single localities in the state of Chiapas.

Keywords : Chiapas; Cryptarrhena guatemalensis; Domingoa gemma; new records; Orchidaceae.
