Eriopus haitensis Crum & Steere, Amer. Midi. Naturalist 60: 34. 1958.
Since the description ofthe genus, Piloseriopus (Sharp, 1986), several species in the genus Eriopus have been examined in regard to the ornamentation on their setae. Among the species for which sporophytes were available to me, three, E. mollis Card., E. parviretis Fleisch. and E. remot ifolius C. Müll., had only elongated, unicellular papillae on the setae. Only one, Eriopus haitensis, had multicellular filaments on the setae and bases ofthe capsules. Crum and Steere (1958) described this species from Haiti, indicating that it was related to E. setigerus Mitt., but had leaves that were more ovate, more shortly acuminate, and with a less differentiated border.
