Puare 146,—Calamus plicatus Bi. The entire type-specimen in the Leyden 
Herbarium. | 
194, CALAMUS MINAHAssE Warb., name only in Herb. Berol. 
Descrtprion.—Very slender, scandent.  Sheathed stem 6-7 cm. in diam. Leaf- 
sheaths not cirriferous, covered like the spadix and leaf-rachis with a rusty-furfuraceous 
removable indumentum, longitudinally striate, gibbous above, obliquely truncate at the 
mouth, irregularly armed with slender, flat, subulate, unequal, scattered, dark, straight» 
slightly deflexed, 10-12 mm. long spines, with which are intermingled other very 
small, and sometimes sub-tuberculiform spinules. — Ocrea very short, reduced to a short 
axillary ligule and to a narrow scabridous margin at the mouth of the sheath. Leaves 
delicate, cirriferous, 35-50 cm. long in the pinniferous part; the cirrus slender, 
filiform, elongate, armed with solitary or more or less aggregate slender claws; petiole 
short or very short (1-3 em. long), flat above, where sometimes spinulous as on the 
first portion of the rachis, convex beneath, where armed with a few long and straight 
‘spines which upwards on the rachis are transformed into scattered unequal and some- 
times very small claws; in its upper part the rachis is bifaced and smooth;. leaflets 
not numerous (14-16 in all) inserted at an angle of 45°, distinctly approximate in 
distant pairs on each side, the pairs sub-opposite and therefore forming 4 very 
distinct groups of 4, separated by a long (8-10 cm.) vacant space; thinly papyrace- 
ous, rather rigid, somewhat plicate, chiefly at the base, otherwise explanate, green 
even when dry, subconcolorous, slightly paler beneath, oblanceolate, gradually narrow- 
ed and acute at the base, rather suddenly acuminate at the summit into a slender 
tip, this bristly spinulous at the margins, with 3-5 slender coste which are almost 
equally prominent and naked on both surfaces and with 1-2 rather distinct secondary 
nerves between the main coste; transverse veinlets very distinct, rather crowded; 
margins finely spinulous, the largest leaflets, the intermediate ones, 15-19 cm. long, 
2-3 em. broad, the uppermost and especially the lowest considerably smaller. 
Male spadiz . . . . . Female spadiz very elongate, slender, subflagelliform, simply 
decompound, with many small remote partial inflorescences; lowest primary spathe 
Wen . ; upper primary spathes tubular, cylindraceous, very elongate, closely 
sheathing, obliquely truncate at the mouth, where prolonged at one side into a short 
erect point, suddenly narrowed at the base into the very slender filiform flattened 
obsoletely angular axial part, rather densely armed with very small deflexed prickles, 
which have 2 light swollen base and a brown tip or are tuberculiform or slender and 
subulate and even 1 cm. long; partial inflorescences 15-20 cm. apart, inserted at the 
mouth of their respective spathe with a distinct axillary callus, spreading, small, the 
largest 10-12 cm. long with 9-10 spikelets on each side; secondary spathes short, 
tubular-infundibuliform, more or less angular, somewhat loosely sheathing, entire, 
truncate and subsearious at the mouth, barely apiculate at one side, unarmed and 
finely longitudinally striate; spikelets inserted above the mouth of their respective 
spathes with a distinct axillary callus, recurved and subscorploidly arched, the lower 
ones, the largest, 2°5-3 cm. long with 10-12 pairs of flowers; spathels narrow and 
more or less angular at the base, suddenly expanded above into a short broadly 
infundibuliform entire limb, which is prolonged at one side into a short usually 
deflexed point; involucrophorum laterally attached outside its own spathel at the. 
base of the one above, sessile or with a short neck, suborbicular, discoid with a
