ceraceous; rostellum entire; stigma semiorbicular, with 
raised and prominent margins. 
Dickasonia is similar in habit to Panisia Lindl., but 
is easily distinguished from it by the lip which is adnate 
to the column, and also by the short column. 
There are but two genera in the subtribe Coelogyneae 
which have the lip adnate to the column, Gynoglottis 
J.J.Smith and the present genus. Dichasonia, however, 
is more closely allied to Panisia and should be placed 
next to it in the classification proposed by Schlechter. 
The genus is named for Mr. F. G. Dickason of Judson 
College, Rangoon, Burma, who has contributed to the 
orchid knowledge of that country through his collections.
