rather small, the pinnæ aboul 10 ini long l)y 1 cm wide with 6 8 pairs of tertiary 

 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 pinnæ 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 Me.Kico 

 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 Nephrodhim propinquum 

 Rr. B., of which I have seen an aulhentical specimen (S), corresponds to the var. 

 hirsuta, but it may perhaps be considered a different species.
