River (1959 Borden, 217, 1396 Copeland)-, northern Luzon (Warburg) . Min-

I have the same species from Malacca, Johor, leg. Ridley 10976; Singapore, leg. 
Hose (1894). 
Aspidium melanorachis Bale. Journ. Bot. 1888. Hephrodium. 315 Sarawak, 
Borneo, leg. Hose is very near.

Diplazium vestitum Presl Epimel. 87, 1849. Hook. Ic. ii. 46. 
By comparison with Hooker’s figure of Cuming’s specimen ^from Leyte, I have 
identified as this species the plant found by Loher at Mabacal and Angilog, 
Rizal Province, March, 1906. It is very much larger than the one represented 
by Hooker; but all the details correspond perfectly, especially the axial parts 
covered with scales and furfuraceous down. The lateral nerves and the sori 
converge in the sinus between two lobes, but they do not touch before the sinus. 
The stipe, which attains the size of a finger, is rough with small warty projections. 
The same plant from Celebes leg. Koorders 16986. 
I distinguish this from the form which I have identified in Bull. Herb. Boiss. 
vi. 1906, 1001, with D. Smitliianum (Bale.) Diels by the shorter sori, which 
touch somewhere before the sinus, by the rough scaly racliis armed like the cost® 
with sharp prickles, and by the more truncate lobes. I have this from Ceylon, 
leg. Wall. 38/275, from Celebes, Bojong, leg. Warburg 15314, Sarasin 108, and 
from New Guinea, Sattelberg, leg. Weinland 1890. 
I must say that these two forms are exceedingly similar and appear almost 
like one specific type in the wider sense. Diplazium dolicliosorum Copel. 1 is inter- 
mediate between D. vestitum Presl and D. Smitliianum; the sori are those of the 
former, but the Imperfect pubescent covering and the truncate lobes are as in the 
second.
