Discusión taxonómica
(In relation to the synonym Adenoderris sororia) Only two collections of this very rare and curious species are known other than the type, the Breedlove collection and the other from Guatemala made over 100 years ago (see Stolze, 1981). Pacheco and Moran (in Davidse et al., 1995) and others have referred to the indusia as peltate, but in an isotype seen, indusia are clearly subcordate and attached at a narrow sinus.A
