A noble species ; remarkable for the alternate lower leaves, 
stout ramuli, the glaucous hue of the latter, as of the petioles, 
and under. sides of the leaves, the large panicles, small 
berries, and conduplicate cotyledons. 
The other species of this genus are P. Senegalense, Spach, 
which is the Hypericum Guineense, Linn., (but perhaps not 
Vismia Guineensis of Choisy), a Senegambian plant, and P. 
Sebrifugum, Spach, fromAngola.

Grand Bassa and Fernando Po, Vogel; Sierra Leone, Don. ; 
Senegambia. 
I cannot distinguish the W. African specimens from those of 
the Mozambique, Mauritius and Madagascar. Vogel remarks 
that it is a shrub, and Don a tree 20 ft. high. $:
