Biinnemeijer's No. 4233 {Sumatra, Mt. Malintang) is distinguished in 

 having the rhizome erect, the stipes tufted, the dimensions smaller (fronds 

 40—50 cm. long; pinnae Z'/z — 10 cm. long, 2 cm. broad). the secondary 

 cegnients regularJy lobate-dentate (the lower not plnnatifid).

J. A. Lôrzing's Nos. 5520 and 5529 from Sumatra {Deli, Sibolangit) 

 differ from the diagnoses and plates given by sevoral authors in having 

 the stipe and rachis deciduously, very minutely castaneo-fibrillose, the 

 pinnae longer and broader, more numerous, the lowest wiîh the longest 

 lobes subacute, the veins more numerous, of the longest lobes sparingly 

 pinnate, the fertile pinnae smaller than the barren, with the lobes more 

 remote, contracted, subrepand, the sori of the pinnate veins terminal on the 

 lowest acropetal and basipetal venules. (Forma contracta).
