of very different and heteregous elements, judging from 
the structure of the pollinia and the shape of the column. 
A monographic revision undoubtedly will find correlated 
criteria with such pollinaria where the stipe is suddenly 
expanded into a receptacle-like cup containing the four 
ovoid pollinia. 
The genus must be typified by 7°. obtusum Bl. to which 
the generic description applies. T'aentophyllum fornica- 
tum Bl., although never described, is validly published 
through a floral analysis in Blume’s Tabellen, fig. 70. It 
has been redescribed and illustrated by J.J.Smith under 
T. biocellatum J.J.Sm.
