186 ` ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. | D. geniculatus 
leaflets, which are quite smooth and baid on both surfaces. It seems, however, 
closely related to D. Forbesi, D. oligophyllus and D. Sabut, The leaf-sheaths in the 
disposition of the eriniferous collars closely resemble those of D. pseudo-mirabilis, 
Pare 80.—Daemonorops macrophyllus Bece. It represents the type specimen 
in Herb. Beccari.

Descriprion.—-High scandent, but flowers also when only 2-3ft, from the ground 
(Scortechini). | Sheathed stem 2°5-4 em. in diameter. Leaf-sheaths not gibbous above, armed at 
short intervals, especially on the upper part of the dorsum, with several sub-parallel, oblique, 
semi-circular or at times complete spiniferous crests or rows of deflexed or spreading 
spines united by their bases into membranous rings; the spines are mostly large, 
unequal, 2-4 cm. long, thinly laminar and blackish; intermingled with these spines are 
slender, brittle, needle-like or setiform spiculae; the parallel rows of spines, as a rule, 
descend obliquely from the rim of the mouth and surround the dorsum of the sheath ; 
some of the lower rows, however, are completely encircling; the mouth is very oblique, 
and is densely armed with long and narrow ascendent spines of which some are as 
nuch as 10-15 em. in length. Ocrex inconspicuous. Leaves large, elongate, 
l1-L:5 m. long in the pinniferous part, and terminating in a strongly-clawed cirrus, 
about as long; petiole elongate, usually 30-40 cm. in length but in vigorous leaves, 
especially in those of the lower part of the stem, as much as 60-80 em., robust, up 
to 15 mm. broad near the base where it is plano-convex; higher up it is slightly 
flattened-bieonvex, or convex beneath, and  obsoletely angular above, conspieuously 
and rather closely armed on the very obtuse edges with very long, erecto-patent, rigid, 
straight, spiky, woody spines that are frequently accompanied, at their bases, 
by others shorter and divergent or digitate; the longest spines are those near the 
base, which are as much as 15-18 cm. long, and become gradually shorter higher 
up, where they are sometimes transformed into digitate, hooked prickles ; 
. : on the 
upper surface the petiole is sparsely and minutely prickly, the prickles 
i being 
often approximate in small series; the dorsum of the petiole is smooth, especially 
at its base; the rachis in the lower portion of the upper surface has an obtuse 
salient angle, and is more or less deeply grooved at the sides, higher up the salient 
angle becomes acute with flat faces; it is smooth all over; on the under surface 
the rachis is armed with 3-naie, or 5-7-naie black-tipped claws. Leaflets rather 
numerous, very inequidistant, more or less distinctly approximate into several groups
