Hal). Luzou, (Prcsl). — I have drawn up the above brief character from 

 Presl's figure, in the absence of any description. It would seem to be a 

 hairy state of D. contigua.

Hab. West Indies, {Prcsl). — The native country of this plant, no less 

 than the different habit and peculiar fructification (as far as can be learned 

 from the figure), would lead to the opinion that it is far removed from 

 Prosaptia .
