Central Madagascar, gathered long ago by Bojer and Hilsenberg, 
and distributed by them as “ P. sagittatum” and “ P. hastatum,” 
both of which names are very appropriate, but already occupied, 
and now refound by Dr. Parker and Mr. Baron. Native name 
* Maharamomby." A near ally of the Indian P. pedunculare, 
Wallich.

has lately gathered P. borbonense, C. DC., in the province of 
Imerina (1280), and the forest of Alamazaotra (1539), and P. sub- 
peltatum, Willd., in the province of Tanala and woods between 
Tankay and the east coast (1519).
