D. microstachys] BECCARI. THE SPECIES OF DAEMONOROPS. 133 
narrow, scarious, distinctly ciliate-denticulate; the point round. Seed oblong (not 
seen quite mature). 
HaBrrar.—Borneo: In Sarawak at Kuching (Beccari P. B. Nos. 1939 and 
250); at Labuan (Lob in Herb. Kew. The Malayan name in Sarawak is “ Ro 
mignac”, The strips cut from its stem are very strong and extremely tough, and are 
therefore frequently used to fasten the iron blade of the “Bilion” (the Malay axe) 
to its handle. Low, who also collected this species in Borneo (Herb. Kew.), gives 
the name of “ Rotang putte duri?" (Rotang having white spines). 
OBSERVATION, — D. ozycarpus is a very well marked species, easily distinguishable 
by the large swelling at the base of the petiole; by the membranous laciniate 
formations which take the place of true spines on the leaf-sheaths, and by the 
ellipsoidal elongate fruit which gradually narrows upward to a conical beak and 
downwards to an acute base. 
PLATE 53.—Daemonorops oxycarpus Bece. The upper portion of a leaf-sheath 
with the petiole and the lower part of a female spadix (in situ) before the anthesis 
(on the left hand side of the plate); from Becc. P. B. No. 250. A fruiting spadix ; 
an intermediate portion of a leaf, upper surface; portion of the sheathed stem: 
from Becc. P. B. No. 1932. J 
DAEMONOROPS OXYCARPUS var. LEVIPES Becc. 
Differs from the “forma typica” in the leaf-sheaths, which are quite smooth 
and entirely devoid of the peculiar sub-foliaceous spines, but are furnished with the 
same conspicuous globose gibbosity at the base of the petiole. 
Hasitat.—Dutch N.-W. Borneo at Lianggagan in the Residency of Sambas.

Descriprion.—Small, Stem erect, about 1 m. high (Lobb). Leaf-sheaths 15-18 
mm. in diam., not gibbous above, open on the ventral side a long way down, 
rusty-furfuraceous, armed with flat, brown-tipped, otherwise light-coloured, 1-2 em. 
long, horizontally seriate, but individually distinct spines, end with other spines 
much smaller interposed between the series of the larger; a few spines 4-5 cm. 
long stand erect near the mouth of the leaf-sheath. ^ Ocrez inconspicuous. Leaves non- 
cirriferous  (alwavs?); petiole rather elongate, smooth and concave on the upper 
surface near its base, flat higher up, underneath strongly convex and armed along 
the centre, at intervals of 3-4 cm., with solitary, straight, and slightly deflexed 
spines, which change into light-coloured claws higher up; the edges are not very 
acute, and are armed towards the base with a few straight, spreading, 2-8 
em. long spines, which in  prefoliation point upwards and leave upon the petiolar 
surface deep impressions of their outline, gradually becoming shorter higher up 
and disappearing where the leaflets begin; the rachis is laterally on the upper surface 
deeply grooved at first and then has an acute, non-prickly, salient angle, and flat
