Discusión taxonómica
(In relation to synonym) Trichomanes hymenoides is very close to T. krausii (q.v.) and can be distinguished by its small size, sessile stellate marginal hairs, lack of stellate hairs in sinuses, the pinnate main lateral veins that appear almost subpalmate, and the broad fronds with overlapping segments. See T. bucinatum for distinguishing characters.A
