" There is no small obscurity about the one or two old species of this genus, and respecting the dis- 
tinction between it and Hydnophytum, which the Dutch botanists ought to clear up. But the present 
species (M. imberbis), notwithstanding that the corolla wants the beard described by Jack, and the forni- 
eate scales mentioned by Blume, is undoubtedly a genuine member of Jack's genus Myrmecodia, and its 
stigma is probably similar to the ‘stigma simplex tomentosum’ of M. tuberosa. But this stigma in our 
plant consists of 4 minute apiculate lobes, terminating a filiform entire style, and surrounded by a kind 
of indusiate margin, which is fringed by a circle of delicate arachnoid hairs. From the analysis I should 
refer Gaudiehaud's M. inermis and AM. echinata to Hydnophytum."—A. Gray in Proceed. Amer. Acad. 
vol. iv.
