On a further Collection of Ferns from West Borneo, made by the 
Bishop of Singapore and Sarawak. By J. G. Bags, F.R.S., 
F.L.S. 
[Read 16th June, 1887.] 
THE present collection is supplementary to one on which I 
reported in Vol. xxii. of the Journal of the Linnean Society, 
pp. 222 to 232, pls. 11, 12. All the species were gathered in 
the Sarawak district, some by Dr. Hose himself and the others 
by his nephew, Mr. Charles Hose, and a few by Mr. Forstermann, 
a collector who visited Borneo in the spring of 1886. The num- 
bers are Dr. Hose's collecting-numbers; those within brackets 
indicate the position of the new species in the sequence followed 
in our ‘ Synopsis Filicum.’ 
216. MATONIA SARMENTOSA, n. sp.; sarmentosa, frondibus 
laxe pinnatis, pinnis 2-4-jugis linearibus simplicibus vel furcatis. 
Niah, Sarawak, Mr. Charles Hose. 
This is a very interesting novelty. It has precisely the fruc- 
tification of Matonia pectinata, but is completely different in 
habit. The main rhachis of the frond is very slender and quite 
naked, like all the rest of the plant. The pinn® are arrangedon 
the rhachis generally in whorls of three or four at a distance 
from one another of 14-2 inches, and are sessile and sometimes 
slightly confluent at the base. They are linear, from 2 to 4 
inches long, simple or forked, obtuse, rigid in texture, } in. 
- broad, with rather indistinct simple or forked free erecto-patent
