The discovery of the var. philippinensis in Borneo gives me cause to 

 remember that the species has also been found in Sumatra some years 

 ago (v. A. v. R., Bull. Btz., 1914, XVI, 22). That habitat is not mentioned 

 in Copeland's „Keys to the Ferns of Borneo" in Saraw. Mus. Journ., II (III) 

 387. Since a second specimen has been found in Sumatra (Mt. Talamau, 

 H. A. B. Bünnemeijer No. 918). 



I did not yet set eyes either on the type from New Zealand or on 

 the variety from the Philippines. 



Both Sumatran plants agree partly with Hooker's diagnosis and plate 

 of the type, partly with those of Christ's var. philippinensis in Bull. Herb. 

 Boiss., VI, 148, tab. II, but more with the former than with the latter. 



The caudex is arborescent, slender (only "/s — l'/2 cm. thick), the 

 pinnae vary in width from I'Aj to 4 cm., the secondary segments are entire 

 to crenate or dentate-serrate, the sori are golden-yellow or brownish-yoUow, 

 the indusia are brown or yellow-brown, eroso-denticulate and marginal, 

 i.e. they consist of the recurved margin of the fertile segments. 



If Christ's diagnosis and plate are correct, then his variety differs from 

 the Sumatran specimens in having the sori rufo-orange, with the indusia 

 grey, medial between the costa and margin, originating from the receptacle.
