Discussion
Type. Savanna, vicinity of ‘‘Misia Kathy Camp,” on mesa between Ptari-tepui and Sororopan-tepui, 1615 m alt, Bolivar, Venezuela, J. A. Steyermark 60238 (holotype F, isotype NY).
Steyermark (Fieldiana Bot. 28: 51. 1951) described Mapania tepuiana under the genus Hypolytrum without giving his opinion as to its taxonomic relationships and its generic status. In my view this species should be placed in the genus Mapania as is discussed under M. imeriensis. In no sense does it belong in Hypolytrum.
