Begonia rostrata

This delicate looking species is from Logo, Tome, on the coast of Guinea.  It is a tuberous species and not tolerant of wet conditions.  I let the soil go dry between waterings by watering only about half as often as my rhizomatous species.  It still requires high humidity I think, although I’m not sure how high as I’ve not tried it in an open-air environment.  It can reach over 12″, but would likely need something to lean on as its stem is not very supportive.  The leaves are small, around an inch, two at the largest.  Each of the white spots has a small hair protruding from its center.


The male flower, very dainty,

The female flower, with a large hook, sits very close to the male,

So close, in fact, it is hard to photograph one without photographing the other.  I suspect this species is at least somewhat self-pollinating due to the close positioning, which at even a slight breeze or jostle from an insect would come in contact with each other.  They have been in bloom at the same time, for roughly the same duration.  Each inflorescence has a single male/female pairing.
