174 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA — [/. annulatus 
The locality of Java given by Miquel (Fl Ind. Bat, iii, 136) for C. manicatus 
is apparently erroneous, as probably is that of Borneo given by Blume for 
D. crinitus, as it is not likely that a species of Demonorops of this group should be 
represented in two rather distant regions with exactly the same characters. 
I refer to D. crinitus a specimen from Sumatra preserved in the Herbarium at 
Buitenzorg (No. 2022) having the label “ Calamus crinitus. Rottan tjentjen. Priaman ^ 
without the name of the collector. This specimen is from a more robust plant than 
those described above; it has the sheathed stem about 2 cm. in diameter, but covered 
with the crinigerous collars, and rows of spiculae as in the others; the leaves are 
also larger, but none are entire; the petiole is 13 em. long, 12-13 mm, broad, flat on 
the upper surface, convex on the back and with a line of small claws along the 
centre, and it is slightly armed on the edges with small prickles; the rachis is flat in 
its lower portion, has slightly spinulous acute edges and narrowly grooved sides, and 
towards the upper end has flat side-faces, and an acute smooth or scantily spinulous 
salient angle; the leaflets are numerous, almost equidistant, linear, 30-35 em, long, 
very acuminate, 12 mm. broad, bristly on 3 nerves on the upper surface, but only 
on the mid-costa on the lower. Probably this specimen collected in West Sumatra 
represents a local variety of the plant growing in Palembang which must be considered 
as the typical. 
Pirate 71.—Daemonorops erinitus B/. Upper end of a stem with a very young 
spadix; portion of the sheathed stem with an entire spadix from which all the 
fruits bave fallen. ‘The specimens in Herb. Beccari from a plant cultivated at 
Buitenzorg. 
7, DAEMONOROPS ANNULATUS Becc. in Rec. Bot, Surv. Ind. ii, 227. 
DescripTion.—Scandent and slender. Sheathed stem 15-16 mm. in diameter; the 
internodes rather elongate. Leaf-sheaths slightly gibbous above, obliquely truncate and 
spinous at the mouth, furnished with several (6-7) broad, complete, membranous, 
spiculiferous, deflexed collars, and with 2-3 other similar collars, equally large, but 
ascendent; these paired collars form between them 2-3 spacious, perfectly horizontal, 
annular ant-harbouring galleries round the stem immediately below the base of the 
petiole; alternating with the double large collars, and half-way between each pair 
is another complete, also perfectly horizontal, spiculiferous ring; the marginant 
spiculae or spines are apparently very brittle, as they have ail fallen off in the 
specimen I have examined. Leaves about 50 cm. long in the pinniferous part, 
terminating in a rather long, clawed cirrus; leaflets very conspicuously aggregated 
into a few remote groups; petiole very long (54 cm, in one specimen), slightly 
flattened-biconvex from just above its base, its edges obtuse, and armed from 
the base upwards with several small claws, smooth on both surfaces, except for 
a few small claws along the dorsum, near its upper end; the rachis has, 
immediately from the insertion of the lowest leaflets, an acute and smooth salient angle, 
with slightly concave side-faces above, while underneath, it is, as usual, armed, first 
with solitary, and then with 3—5-nate claws; leaflets very few, only 19 in one specimen,
