Related to P. pleurobotryosa Donn. Sm., with which it has been confused, 
P. vestita is notably different in having coarse villous indument of mostly 
simple hairs, a villous-tomentose ovary with style short villous at base, and large 
thin leaves distinctively and conspicuously dentate, mostly with sharp small 
teeth. In P. pleurobotryosa the indument is denser and of conspicuously stellate 
stipitate hairs, the ovary is only short villous at apex with the style glabrous, 
and the margin of the small subchartaceous leaves is rather obscurely crenulate.
