The nearest allies of this species are G. fruticula J. J. 8. and G. salmonea 
J.J. 8. It differs from the former by the smaller flowers, differently shaped 
petals, relatively broader lip, edentate clinandrium, and from the latter by the 
weaker stems, shorter spathe, somewhat smaller flowers, differently shaped 
petals, broader lip, edentate clinandrium. 
The material seen consists of two stem-tips, with one flower and a 
flower-bud. |
