regularly infundibuliform, similar to those of a Calamus, and from this apparently 
related to D. longispathus. 
Of D. acamptostachys I have seen only an intermediate portion of a leaf and a 
spadix with very young fruits. ;

Calamus ruptilis H. Wendl. (name only in Herb. Kew.). 
Description,—Scandent; apparently large.  Leof-sheaths armed at the mouth with 
numerous, very large (as much as 20-25 em. long and 3-5 mm, broad), erect, laminar 
spines, and all over the body with numerous similar ‘spines but shorter. Leaves very 
large, terminating in a rather robust cirrus; petiole armed at its base with large light- 
coloured, laminar, unequal (1-5 em. long) spines, which point in different directions; 
rachis smooth on the upper surface; underneath it is at first smooth or armed sparingly 
with solitary claws, which become ternate higher up and rather closely and regularly 
half-whorled towards the end, especially on the cirrus. Leaflets numerous, equidistant, 
rather distant (.—7 cm. apart), papyraceous, rather glossy, green and concolorous on 
both surfaces, ensiform or very narrowly lanceolate, broadest about: their middle and 
thence tapering towards an acute base, and very gradually acuminate to a finely 
subulate slightly asymmetrical and bristly tip; on the upper surface the mid-costa is 
acute and bare and the secondary nerves are slender and also bare; on the lower surface 
the mid-costa alone has a few long bristles, or is entirely bald; transverse veinlets 
very numerous but indistinct; the margins smooth, except near the apex, where they 
are furnished with a few spinules, longer and more numerous on the small sub-apical 
indentation of the lower margin than elsewhere; the largest leaflets are apparently 
those near the base, and are 60 cm. long and 3 em. broad; other leaflets, probably of 
‘the intermediate portion, are 35-40 cm. long and 2-3 cm. broad; some of the upper 
end measure only 23 cm. in length and 3 cm. in width. Female spadiz large; one, 
which apparently wants only its peduncular part, is 75 cm. long, and carries 4 partial 
inflorescences ; all the axial parts are of a cinnamon-brown colour when dry, and are 
more or less fugaciously covered with a thin rusty-brown, furfuraceous indumentum; 
the main axis is thickish, 18 mm. in diameter at its base, and terminates in a tail-like 
unarmed appendix, which is about 20 cm. long and is sheathed by several incomplete 
‘spathes; the internodes are straight, subterete or obsoletely angular, slightly swollen 
at the nodes; primary spathes thickly coriaceous, the outermost not seen by me; 
the others elongate; one of these, apparently the second, is 44 cm. long and 4 em, 
broad, very narrowly lanceolate, very acuminate, spread out flat, quite unarmed, 
carinate especially near the apex, coarsely striate, or ridged with about 10 strong 
costae on the back; the inner surface is also striate but the ridges are finer and closer ; 
partial inflorescences robust, spreading; the lowest, which is also the largest, is 40 cm. 
long and has 10 large spikelets; of these, one is apical and the others are alternately 
.distichous; the succeeding  inflorescences are shorter and have fewer spikelets; the
