172 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [D. crinitus 
I have preserved only two specimens of D. formicarius of very different sizes; 
one (No. 1923) is much less stout than the other (No,2552); the first has a leaf 
30 em. long in the pinniferous part, and terminates in a slender cirrus of equal 
length; in the other, shown in the plate, the  pinniferous part is 65 cin. long, and 
terminates in a rudimentary cirrus. One of Hewitts specimens is stil more robust 
than my No. 2552; it has a sheathed stem 2 cm. in diameter, the leaves are 
80 em. long in the pinniferous part, and terminate in a cirrus about ‘as long, 
armed at very regular and short intervals with half-whorls of small claws; the 
spadix is 30 cm. long, and bears mature fruits. Another of Hewitt's specimens has 
fruits quite identical with those of the preceding, but has a sheathed stem only 12 
mm. in diam. and one leaf is only about 45. cm. long in the pinniferous part, and 
the leaflets are 15 em. long and 10 ram. broad. 
PrnarE 70.—Daemonorops formicarius Bece. Portion of the sheathed stem with 
two spadices of which the fruits have fallen; upper end of the same leaf attached to 
the stem. From P. B. No. 2552 in Herb. Beccari.

Description.—Scandent, slender. Shesthed siem 9-12 mm. in diameter or at 
times more.  Leaf-sheaths slightly gibbous above, furnished irregularly with 2-3 
complete, annular, membranous, spiculiferous, deflexed collars; interposed between 
these are 3-4 or even at times more collars often incomplete, some fringed with 
spiculae pointing upwards, others with spiculae pointing downwards or horizontal; the 
spiculae are very slenderly criniform and brittle, quite black, shiny, unequal, short, 
or as much as 3-4 cm. in length, but of uniform thickness at their base; the 
mouth of the lesf-sheaths and the base of the petiole are also armed with small 
transverse, interrupted series of similar spiculae. Leaves rather elongate, terminating 
in a slender cirrus, with rather numerous leaflets which, from as far as can be 
judged from the Herbarium spevimens, are more or less inequidistant, but never 
grouped, in young plants or in the lower part of the stems; but in the upper 
and floriferous end are almost equidistant; petiole of moderate length (10-20 em, 
long, 3-4 mm. broad) flattened-biconvex with not very acute edges which are 
sometimes armed very sparingly with remote, short, straight or slightly hooked » 
prickles, otherwise smooth on both surfaces; rachis with an acute, smooth, salient / 
angle and flat side-faces on the upper surface and armed underneath with small 
solitary claws, which at the upper end and especially on the cirrus become fermés: 
leaflets papyraceous, green and concolorous on both surfaces, linear-lanceolate, broadest
