Note
|
The overall appearance of the type specimen of this species is very close to that of P. arborea, but the absence or extreme reduction of the involucre is a clear distinguishing feature. The peduncle is also longer than that of the buds of most collections of P. arborea examined. Few other collections of this genus from areas similar to the type locality of P. aperta have been seen, and in their absence Croizat's judgement that this is more than an aberrant individual must be accepted. Known only from the type collection.
