This specimen is extremely interesting, falling
somewhere around the poorly understood taxa known
only from flowering material, Aphyllarum (from Mato
Grosso) and Scaphispatha (from Bolivia, pssibly Ceara),
eind Xanthosoma. This material has the broad and
coherent styles of Xanthosoma, supposedly characteristic
of that genus. However, it is surprising to see it flower
without leaves. There seem to be two anatropous ovules
in each of two libaules which suggests Scaphispatha (presumed
misplaced in Aroideae) rather than Aphyllarum S. Moore.
For the moment I suggest this material be handled as
Aphyllarum tuberosum S. Moore.
