BORNEAN FERNS, 135 
The pinnap of Brooks' specimen are exactly like Cuniiiig'aj but Brooks' 
spt'cimen includes also the base of the raehis, which bears leaflets the pinnules of 
M-hieh are deciduous, leavin<r sharp spines, in one instance branched. I suspect 
that this is also AJsophila ramispina Hooker.

Sarawak, Peni-isscn mountain, alt. 150 m, Brooks 57. 
Near to C. squamuJata (Bl.) but having long parapliyses, and to C. ohscura 
(Scort. ) but the basal scales entire; and differino: from both in the mostlv blunt 
pmnuies.

Sarawak, Penrissen mountain, from 900 m to the sumiuit, eonunon, Brooks 59. 
A relative of C. ohscura (Scort.) from which it is sharply distinguished by 
the falcate lobes. The point of the lobe usually receives the uppermost acroscopic 
vein, instead of the apex of the costule; the two forks of a veinlet sometimes 
finite again. 
This is distinguished from the group of C. glabra by the numerous pale scales 
on the stipe.
