published Landolphie are not described as such. The tube

cannot be generic distinctions if the fruit coincides. 
Heudelot’s Senegambian collection comprises what appears 
to be a fifth species, in some respects resembling the L. florida, 
but with rather smaller flowers and an entirely smooth ovary, 
which nevertheless is unilocular, as in all the other species.
