This member of the
Orchidaceae family was
given this name by Leslie Andrew Garay and George C. Kennedy in
1976. It is found from Guatemala, Honduras and Belize up in
Mexico, growing as an epiphyte in rain forests with lots of water and
little to some sun. The pseudobulbs can grow to seven centimetres,
the whole plant up to 30 centimetres, and the inflorescence with the
yellow, maroon and white flowers up to 45 centimetres.
The genera name is named for for
John Ross, 19th century plant collector in Mexico and Latin
glossum; 'tongue'. The species name means 'big'.
