D. oxycarpus | BECCARI. THE SPECIES OF DAEMONOROPS. 131 
OssERVATIONS.—AÀ mong the species of the group of D. Draco, to which D. leptopus 
evidently belongs, it is easily distinguishable by its very hard, woody, almost 
polished leaf-sheaths; by the equidistant leaflets; by the very thick woody spathes ; 
by the small ovoid non-resiniflous fruit; and by the oblong seed, only slightly 
ruminated. 
I have seen portions of Griffith’s type specimens of D. leptopus, but I have 
based the description mainly on Scortechini’s and King’s specimens. 
Griffith (l. c.), after the description of D. leptopus, quotes (last line, p. 82) fig. 
IV, plate ccxvi, as giving representations of the analysis of its flowers, but certainly 
erroneously, for this figure represents male flowers, and Griffith describes only the 
female plant of the sbove-mentioned species. 
. I have reduced D. congesta of Ridley to D. leptopus after a very careful 
analysis of a specimen kindly sent to me by its author; it is true that this 
specimen (which is very incomplete, and has very immature fruits) has the spikelets 
with the flowers more approximate than usual; but this specimen does not appear 
to me quite normal.

Descrtprion.—Scandent. Sheathed stem 2:5-3 cm. in diameter. Leaf-sheaths coated, 
at first, with a white cottony fugacious tomentum, and later with a thin, adhe- 
rent, persistent, dark  rusty-brown covering, very conspicuously and peculiarly 
gibbous or swollen at the bases of the petioles, armed in a very peculiar way 
with epidermal formations hardly to be called spines, (for. they are not or only 
very slightly pungent), lamelliform, or thinly papyraceous, exsuccous or scarious ; 
they are elongate (2-3 cm. long, 3-6 mm. broad), longitudinally 
striately-veined, laciniate-fimbriate, or divided into many  filamentose strips, 
deflexed, solitary, or more or less confluent; the mouths of the sheaths are very 
obliquely truncate and unarmed; the ocrea is very short, prolonged into a short 
scarious liguliform axillary appendage. Leaves large, about 2 m. long in the pinni- 
ferous part, and terminating in a comparatively slender cirrus; petiole elongate 
(about 60 cm. long), biconvex from near the base, almost smooth on both faces, 
the edges obtuse and strongly armed near the base with rigid, needle-like, 
subterete or slightly flattened (non-laminar), light-coloured, 4-6 cm. long spines, of 
which the lower are usually geminate and divergent and the higher gradually diminish 
in thickness and length and are more distant; rachis in its lower portion armed 
beneath first with solitary, then with 38-nate, and finally on the cirrus, half 
whorled claws; on the upper surface the cirrus is at first obtusely convex and 
then  bifaced with a very acute,  non-prickly, salient angle; leaflets very
