Dendrochilum Clemensls: 



rotundatus, apiculatus, 4 mm. lon- 

 gus ; lamellae 2, longae. Columnar 

 laciniae laterales ferine basilares, 2 

 mm. longae, circa 1 mm. latae, in- 

 sequaliter ad apicem bilobatse, lobo 

 superiore elongato ; ala terminalis

 from both of which it is clearly

 lateral wings of the column.
