 Hk. 2nd Cent. t. 47. BracL p. 230. 



Hab. Fiji, Aneiteum. — Near D. campyhura, but much more finely cut and thinner 

 in texture, and sori different.

 lobes ; texture coriaceous ; rachis and especially the under surface pubescent ; 

 mins beneath prominently raised ; sori 2 to 20 to a segment, placed one or more

Hab. North of India, Ceylon, Malayan and Polynesian Islands. — This has the stature 

 and habit of D. Speluncce combined with the coriaceous texture and prominent venation 

 of D. strigosa.

 Polynesian Islands, southward to Norfolk Island, and Queensland, Madagascar, Bourbon, 

 West Tropical Africa, and Macalisberg mountains, west of Natal. West Indian Islands, 

 southward to Brazil. — This is much more tender in texture than D. strigosa and hirta, 

 so much so, that the pinnae are liable to shrivel up when the plant is gathered in a hot 

 country. It resembles Dichsonia ruhiginosa considerably in general appearance, and has 

 a wide geographical range.
