Here it is:
I labeled the young plant here as P. stenolobum for
1. the length to width ratio of the larger leaves
especially are greater than 3, which fits P.
stenolobum rather than P. williamsii.
2. the petioles of this plant have a rather smooth
upper surface, which is indicative of P. stenolobum.
Both P. williamsii and P. stenolobum are currently
considered valid species.
