faintly channelled along the middle, light-brown yellowish with a dark red-brown 
marginant line which broadens towards the tip; this somewhat prolonged, triangular, 
not very adpressed, erosely toothed. Seed (very immature) apparently deeply pitted

OsseRvaTions.—This species is founded on the upper portion of a leaf and on a 
portion of a spadix with half-mature fruit, It must be very uncommon as it has 
not been found again by any of the modern collectors. It is distinguished in the 
group of C. palustris by its narrow elongate equidistant unicostate leaflets, which have 
the mid-costa and one slender nerve on each side of it sprinkled with fulvous bristles. 
above, and underneath only the mid-costa closely hairy. In the fruit-spadix and 
especially in the structure of the spikelets, and in the form of spathels and involucre 
it approaches C. palustris, and in the narrow leaflets €. viridispinus, C. simplex and 
CO, bubuensis.

153, CALAMUS BUBUENSIS Becc. sp. n. 
Description.—Slender and apparently scandent. Sheathed stem about 12 mm. in 
diam. Leaf-sheaths rusty-furfuraceous, very densely armod with very unequal horizontal 
or slightly deflexed solitary spines of which the larger ones laminar, often slightly 
sinuous or undulate, light coloured and of a greenish hue with a dark tip, broad and 
often laciniate at the base, 10-15 mm. long; with these are intermingled many others 
much narrower and often setiform. Ocrea rather elongate, brown, exsuccous, brittle, 
hispid. Leaves cirriferous, in one specimen 55 cm. long in the pinniferous part; the 
cirrus filiform, minutely clawed; petiole rather elongate (7 cm. long), flattish and 
smooth above, convex beneath, armed at the sides with a few horizontal straight 
spines; rachis armed at the sides with short prickles and along the middle beneath 
with claws which are solitary at first and become ternate towards the summit; in the 
upper surface acutely bifaced from a little above the base and smooth throughout; 
leaflets not numerous (31 in one leaf), very inequidistant, irregularly grouped, but 
not very approximate by their bases, all in one plane (not pointing different ways) 
papyraceous, rigidulous, linear-lanceolate, very acuminate into a subulate and bristly 
apex, green, slightly paler beneath, tricostulate, the mid-costa acute and the side costae 
slender, all naked on both surfaces; transverse veinlets sharp not very crowded, much 
interrupted ; margins smooth; the largest leaflets, those a little above the base, about 
20 cm. long, 12 mm. broad; the upper ones gradually shorter but scarcely narrower. 
Male spadiz simply decompound, rigid, straight, slender, erect, shorter than the leaves 
(40 cm. long in one specimen), not cirriferous at its summit, with 4-5 gradually 
diminishing partial inflorescences, quite unarmed; primary spathes narrowly infundi- 
buliform, slender -and flattened. at the base, membranous or papyraceous and rather
