I have the plant right next to a robust specimen of A. alba and the
morphological differences are quite clear once you see them next to each
other. There are similarities, however, as there are between A. alba
and A. sarawakensis. For me, the tell-tale sign will be the morphology
of the inflorescences when they finally appear. The A. alba actually
has much more prominent venation on both the abaxial and adaxial
surfaces and a heavier substance overall to the leaf than has this plant
or A. sarawakensis.
In some respects, one could say that this plant appears somewhat
intermediate between A. alba and A. sarawakensis, as A. sarawakensis
petioles have a rough, almost peach-fuzz texture and both this plant and
A. alba petioles are smooth to the touch. But then there is the color,
which is characteristic of neither of the two species in question!
I would argue against this plant being a hybrid, as one of the most
likely parents, A. plumbea Nigra, has never produced pollen in my
experience, implying to me that it may be a sterile hybrid itself, or a
An intriguing enigma, for sure!
