rather small, the pinne about 10 cm long by 1 cm wide with 6—8 pairs of lerliary 
veins. A more different form occurs in Southern Brazil and adjacent countries. 
I call it 
var. longipinna nov. var. 
It is much larger than the type, having pinnz: up to 40 cm long by 30 cm 
wide with about 15 pairs of veins; further it differs by its thinner texture and 
scarcely raised veins; it is hairless and, as a rule, also eglandulose. : 
D. gongylodes is found in America from Florida to Argentina and from Mexico 
to Panama, while it apparently is unknown from the South American Andes. In 
the Old World it occurs in about all tropical and subtropical countries, extending 
to Japan and Corea. The South African form (Aspid. Ecklonii Kze.) is nearly quite 
identical with the American var. glabra and similar forms are found in Asia. The 
Australian and Polynesian form originally described as Nephrodium propinquum 
Rr. B., of which I have seen an authentical specimen (S), corresponds to the var. 
hirsuta, but it may perhaps be considered a different species.
