By comparison with Hooker's figure of Cuming's specimen from Leyto, I have 
idi'ntiJied as tliis si>ccies the plant found by Loher at Mahaeal and Angilog, 
Rizal Province, March, 1906. It is very much larger than the one represented 
by TTookcr; but all the details correspond perfectly, esjK'cially the axial parts 
covered with scales and furfuraceous down. The lateral nerves and the sori ■ 
converge in the sinus between two lobea, 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 10980. 
I distinguish tins from the form which T bave identified in Bull. Herb. Boiss. 
VI. 1900, 1001, with D. Smitkianum (Bak.) Diels by the shorter sori, which JL 
touch somewhere before the sinus, by the rough scaly rachis armed like the costse 
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 tliese two forms are exceedingly similar and appear almost 
like one sj>ecific type in the wider sense. DiplazUtm dolichosorum Copel.^ is inter- 
r 
mediate between D. vestitum Presl and D. Smithianum ; the sori are those of the 
former, but the im)>erfect pubescent covering and the truncate lobes are as in the 
second.
