182 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. — [D. oligophyllus 
one specimen), aggregated into 4 groups, separated by long vacant spaces; 
they are papyraceous, rigidulous, green, apparently paler beneath, narrowly oblong- 
oblanceolate or broadest above the middle, tapering thence gradually towards the 
base and shortly acuminate, sometimes rather abruptly, to a bristly caudiculate 
tip; on the upper surface they are rather distinctly 3-costulate, če., they have the 
mid-costa and one sharp nerve on each side of it; all 3 carry short black bristles 
from about the middle upwards; on the under surface the mid-costa alone i8 
minutely  bristly-spinulous in its anterior half; transverse veinlets sharp, rather 
numerous; margins minutely and rather closely spinulous; in the groups the leaflets 
are all in one plane, and rather approximate, but not very regularly set; in the 
lowest group more numerous (6 on each side) and also larger (up to 30 em. long 
and 3 cm. broad) than in the upper gxoups; the terminal group is composed of 4, 
that are 10-12 em. long, and 15-20 mm. broad.

Oxservations.—Of this I have seen only an entire leaf with a portion of the 
sheathed stem. ‘This specimen is apparently gathered from a plant not yet full grown, 
as the leaf is only rudimentarily cirriferous. In the absence of more compiete 
specimens I remain uncertain if the differences existing between D. Sabut and 
D. oligophyllus are specific, or result from peculiar conditions of vegetation. D. Sabut is 
also closely related to D. Forbesii, but in the latter the leaflets are not distinctly tricos- 
tulate. D. Sabut differs from D. oligophyllus in the sheaths being bristly-spinulous at the 
mouth and more regularly armed with complete horizontal rings of spiculae; in 
having larger leaves with terete petioles and more groups of obleng-oblanceolate 
leaflets and these bristly on 3 nerves on the upper surface. 
Puare 77.—Daemonorops Sabut Becc. It represents the entire Scortechini 
specimens in Herb. Beccari.

DzscRrPTION.—Seandent, slender. Sheathed stem 9-12 mm. in diameter.  Leaf-sheaths 
eylindrical, truncate and unarmed at the mouth, covered in youth with a rusty, 
.cottony down, later glabrous, rather thin, easily splitting longitudinally, slightly 
gibbous above, furnished with 3-4 complete, membranous, green, reversed collars, 
formed by the confluent bases of numerous, very slender, needle-like, unequal, at 
times very long, black or spadiceous, shining spiculae; with these, the leaf-sheaths 
have many either complete, or more or less interrupted, rows of similar, but 
smaller, confluent and ultimately deciduous spiculae; all the collars and rows of 
spines are reversed, and none point upwards. Oerea obsolete. Leaves small, 70-90 cm. 
long, including the petiole and the cirrus; the pinniferous part is very short, and
