From D. replans D. asterothrix can be di- 
stinguished by its size, never rooting apex, its soft- 
hairy rachis and stipe, setose sporangia and its 
whole habit. The rhizome bears often under the 
long-stalked fertile leaves a rosette of small sterile 
ones. — The following specimens are very uniform; 
several of them from various herbaria were deter- 
mined by Dr. Christ as A. dissidens Mett., under which 
name the Guatemalan specimens were distributed 
by DoNNELL SMITH. 
Cuba: Prov. Oriente, caverns of Thermopyle, Monte Libano, 
600 m, Maxon nr. 4240 (W)

Not essentially different from the type, but 
the basal pinne the largest (small, reduced pinna 
always absent) on longer petioles (2 mm _ long), 
stipe and rachis with fewer or no long soft hairs. 
JENMAN describes the indusium as distinct; I have 
failed to find it.
