€. Lauterbachii | BECCARI MONOGRAPH OF THE GENUS CALAMUS. 491 
195. Catamus LaurERBACHI Bece. sp. n. 
Description.—Scandent and apparently rather slender. Leaf theiitha. oeste. ith 
a dark furfuraceous indumentum, densely armed with very small, triangular, obliquely 
inserted, ascendent prickles, which are about 2 mm. long, flat beneath and tumescent 
above at their base. Ocrea probably very large at its base; the portion seen by me 
marked by transverse interrupted spinescent ridges or crests. Leaves not cirriferous, 
short, in one specimen 40 cm. long; petiole relatively long (9 cm.), under the lens 
scabridulous-furfuraceous, yellowish-brown, flattish above near the base, then slightly 
convex and sprinkled with small spinescent tubercles: beneath also rather convex, 
unarmed near the base, spinous upwards like the first portion of the rachis, the 
margins very obtuse, not or sparingly tubercled-spinulous; rachis rather stout, acutely 
bifaced shortly beyond the base above, armed beneath with very small confluent 
(in groups of 3-5) and irregularly subverticillate broad-based and black-tipped 
claws; leaflets not numerous, 6 on each side, with a bilobed one at the summit, not 
very distinctly approximate into three groups, the pairs of one side not very 
approximate, opposite or nearly so to those of the other side, subpergamentaceous, 
rigidulous, glabrous, slightly longitudinally plicate, sub-concolorous and almost shining 
on both surfaces, lanceolate or oblong-lanceolate slightly concavo-convex or cochlea- 
riform, attenuate to the base and with a rather distinct axillary callus at their 
insertion, rather suddenly narrowed at the summit into a short and at the sides 
bristly-spinulous tip; the mid-costa acute and raised above, obliterated beneath, 
naked on both surfaces; secondary nerves 2-3 on each side of the mid-costa, very 
slender and indistinct on both surfaces; transverse veinlets very fine, very crowded 
and much continuous; margins acute (not thickened by a marginal nerve), fur- 
nished with relatively strong and short spinules: these closer, longer and more, 
spreading towards the summit ; the largest leaflets, the intermediate ones, 18-21 cm. 
long and 4 em. broad: the lower and higher ones shorter but not nerrower: the 
two of the terminal pair counate for two-thirds of their length. Male spadiz 
short, about as long as the leaves, with 4 partial inflorescences (in one 
incomplete specimen ); primary spathes covered with a removable fuscous furfu- 
raceous indumentum, loosely sheathing, papyraceous, exsuccous and partly decayed 
when the flowers are expanded: the first strongly flattened, two-edged, the edges very 
acute and closely serrate with ascendent spinules, prickly on the faces: the upper ones 
enlarged above, split on one side, narrow and tubular at the base, where armed 
with very small tuberculiform prickles; partial inflorescences with very approximate 
not distinctly bifarious spikelets, forming small compact cupressiform panicles which 
are 6-10 cm. long and arise erect from their respective spathe; secondary spathes 
bracteiform with a short basal tubular part and suddenly expanded into a spreading, 
broadly ovate, acute, membranous, exsuccous and ultimately marcescent limb; spikelets 
thick and short, 1-2 cm. long, with very closely packed and apparently pluriseriate 
and not bifarious flowers; spathels bracteiform with a broad concave obtuse striately 
veined limb and sprinkled with fuscous scales like the other appendicular organs . 
involucre more or less irregularly cupular, often transversely evolute and subeymbi- 
form or subbilobed, the lobes obtuse. Male flowers rather large, about 5 mm. long ; 
the calyx coarsely striately veined and scaly-furfuraceous, divided about midway 
down into 9 broad ovate obtuse lobes; the corolla twice as long as the calyx,
