62 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. (D. hygrophilus. 
confluent spreading spines, which cover also a good part of the beak; second spathe 
armed almost to the apex of its beak with straight, long, erect, slender spines ; 
spikelets of the lower part of the branchlets about 3 cm. long, with about six 
flowers on each side; spathels bracteiform, concave, rather large, acute, subtending 
the involucre; the latter cupular, rather deep, shortly bidentate and _ obsoletely 
two-keeled posticously. Male flowers oblong, 5-6 mm. long. The corolla twice 
as long as the calyx. 
Hasirar.—First discovered by Grifith’s collector at Malacca, Found again by 
H. N. Ridley in 1900 on Bukit Soga in the State of Johore, No. 11209. 
OsnsERVATIONs.— Of D. malaccensis I bad not seen an authentic specimen, and 
therefore it remained to me a rather doubtful species. Recently, however, I have 
rec it i» Ridley’s specimen above mentioned, which agrees perfectly 
with the quoted plate of Griffith’s work. The spadices represented in that plate 
want the outermost spathe, but the acutely trigonous leaf-rachis with very approxi- 
mate, equidistant and relatively broad and large leaflets are very characteristic 
The rather numerous, erect, long spines, which cover the beak, even of the second 
spathe, form a good character. It approaches D. grandis.

Description.—Scandent (ascending, Scortechini), robusti.  Sheathed stem 4 cm. in 
diameter, Leaj-sheaths strongly gibbous above, covered (when young) with a thin, brown 
violaceous indumentum and armed with unequal, flat, laminar, elongate-triangular 
or comparatively short and broad (5-20 mm. in length and 4-5 mm. broad 
at the base), deflexed or obliquely inserted, solitary, yet more or less distinctly 
seriate spines; in the newly exposed sheaths the spines leave on the tomentum 
an impression of their outline, which disappears later. Leaves rather large, 
2-275 m. long in the pinniferous part; petiole rather short (about 20 cm. long in 
two leaves) 2 em. broad, flattish and smooth on upper surface, convex on lower 
where sparsely armed, as the trst portion of the rachis, along the centre line and at 
the sides with solitary, rather robust, straight prickles; the margins acute, not or 
very slightly prickly ; on the lower surface of the rachis the prickles soon change into 
claws which at first are solitary, then geminate or ternate and near the apex as 
on the cirrus, half-whorled ; on the upper surface the rachis is smooth throughout, at 
first convex and with an obtuse, salient angle which becomes very acute with two 
flat or slightly concave side faces upwards; the cirrus is a good deal shorter than 
the pinniferous part (in two leaves). Leaffets very numerous, very olosely set, 
equidistant, papyraceous, rather rigid, green on both surfaces, narrowly linear, 
gradually acuminate to a fine, subulate, not bristly or at most slightly spinulous tip, 
shortly and rather suddenly narrowed towards the base, where distinctly retroplicate ; 
the mid-costa slender but very sharp, furnished as well as one costula on each side
