with this species a specimen from Jamaica, leg. W. R. Maxon n. 2370 (HC). 

 Another specimen from Puerto Rico leg. Sintenis n. 4571 (HC) also belongs here. 



A near ally of D. heteroclita and it ditTers, like that species, from D. diplazioides 

 by the lamina being gradually narrowed downwards through a long row of reduced 

 pinnæ and by the basal pair of veins reaching the margin above sinus. It differs 

 from Ü. heteroclita by its denser pubescence, the long-acuminated and very distant 

 pinnæ (3 — 4 cm. between two pinnæ of the same side) and by the acute segments 

 being separated by broad, open sinus. About 10 pair of veins, sori all elongated, 

 at la.st confluent and ending about the same distance from edge and midrib.
