360 KEYS TO THF FERNS OF BORNEO 
31. D. HIRTIPES (Bl.) O.K. 
Kinabalu. 
Java. 
The texture of this fern is as described by Blume, 
“membranaceous”; I have the same species from Java, 
where there is also a distinct, less cut, subcoriaceous 
species, which is probably Aspidium atratum Wall; This 
species, whatever its name, is common in northern 
Luzon; and I have it from China. 
32. D. procurrens (Mett.) O.K. 
Sarawak. 
Malaya to India. 
33. D. Hewittii Copel. 
Sarawak (Bungo range).

35. D. motleyana (Hooker) C. Chr. 
Sarawak, Dutch Borneo. 
Endemic. 
Veins free in the fertile frond, anastomosing in the 
sterile. Closely related to D. crassifolia (No. 21). 
36. D. parasitica (L.) O.K. 
Nephrodium molle R. Br.

here, but the sori are not nearly terminal.
