Hapirat.—The Philippines: Island of Mindanao at Todaya (Mount Apo), district of 
Davao, in wooded ravines at about 300 m.; collected in October 1909 by Mr. Eimer 
(No. 11938). 
OpseRvaTIons.—It approaches C. palustris and the allied species OQ. Moseleyanus 
and ©. mindorensis in the male spadix, the female spadix being unknown, It is 
easily distinguishable by its distinctly geminate leaflets, which keep a deep green 
colour even in the dried specimens, and are quite bare of hairs and spinules 
(at least in the leaves of the adult plant) except ^ccasionally a spinule at the base 
of the mid-costa on the upper surface. |

OssERVATIONS.—-] have not seen the specimens from Negri Sembilan, which Ridley 
names C. palustris, and do not know if they belong to the “forma typica" or to the 
var. malaccensis, as Scortechini’s No. 506, also quoted by Ridley, certainly does.

C. dumetorum Ridley, Mat, Fl. Mat. Penins ii, 211. 
Mr. Ridley has kindly forwarded to me the type of his C. dumetorum No. 11983, 
collected at Lahat near Ipo in Perak, which is undoubtedly referable to the 
veriety malaccensis of O. palustris, The specimen is represented by portions of leaves 
and by portions of male spadices with very young flowers. "The leaflets are in pairs 
on each side of the rachis, occasionally with solitary ones interposed between the 
pairs; they are elliptical-lanceolate, exactly as in the type of the variety (Scorte- 
chini’s specimens); one spadix, wanting only its base, is about 90 cm. long; the 
leafsheath is armed with very unequal laminar spines, some being as much as 35 mm. 
in length, others only 3-5 mm. The primary spathes are armed with only a very - 
few prickles ; secondary spathes quite smooth.

Description.—Scandent and of moderate size. Sheathed stem 3 cm. in diameter. 
Leaf-sheaths thickish, woody, gibbous above, densely armed with solitary, scattered, 
straight, horizontal, narrowly laminar spines, which are 8-10 mm, long, and leave 
a very distinct impression of their outline above them on the surfare of the
