on each side of the rachis or at times almost equidistant, otherwise as in the 
typical form, but the margins not so strongly spinulous. Spadiz with smooth primary 
epathes. 
HanrrAT.—Palawan: in old clearings, local quite common, Curran No. 3613 
(male plant); at Puerto Princesa, J. Bermejos No. 191, 196 (female plant); all 
the above specimens in the Herbarium at Manila; Brook’s Point (Addison Peak) also 
in Palawan (Elmer No. 12607°. 
OnsERVATIONS.— Ít slightly differs from typical C. mollis Blanco of Luzon, by 
its leaf-sheaths being smooth, or almost so; in any case the few spines with which 
they are armed are much more robust than usual. It is barely distinguishable 
from C. Meyenianus Schauer by the ocrea being more or less spinulous, and by 
the leaflets having more strongly  spinulous margins. C. Mceyenianus itself is 
scarcely a distinet species and had better be considered as a variety of C. mollis 
Blanco. Elmers specimen No. 12607, which has no leaf-sheaths is indistinguishable 
from the typical C. mollis of Luzon.

HanrrAr.— Philippines, Luzon, Lamao River, Monte Mariveles, Whitford No. 80;

Descriprion.—A plant more robust than usual, but connected with the more 
slender forms by numerous intermediate specimens, Sheathed stem .2*5-3 em, in diameter. 
Leaf-sheath densely armed, especially at the mouth, with flexible, acicular, nearly 
filiform spines, Leaves up to 1:20 m. in length, with the petiole armed on both 
surfaces with scattered prickles; leaflets distinctly geminate on the lower part of 
the rachis, rather numerous, narrowly lanceolate, strongly spinulous on the margins, 
on 3 nerves of the upper surface, and on the mid-costa underneath. 
I have examined a very iarge number of specimens of C, mollis and I have 
found that it is a very variable plant as to the general dimensions of the stem (from 
1 to 3 cm. in diameter) and as to the spinescence of the different parts. It is 
therefore difficult to establish well defined varieties of it, as one merges into the 
other by intermediate forms.

DESCRIPTION.—Scandent, apparently rather slender. Sheathed stem . . . Leaf-sheaths 
. . . Leaves (not cirriferous) very regularly pinnate; petiole elongate, about 1 em. broad 
at its base, somewhat flattened-biconvex, very densely beset on the upper surface 
with very unequal, straight, scattered, needle-like spines—of which the largest are 
10-12 mm. long—intermingled with many others much smaller; the lower surface 
is smooth except for a few solitary claws along the centre; the margins are acute 
and armed with spreading acicular spines longer than those on the upper 
surface, Rachis glabrous, armed underneath, in its upper part, with a single line
