C. perahensis.] ^ BECCARI. THE SPECIES OF CALAMUS.—SUPPLEMENT. — i 47 
flattened, two-edged main axis; are of a cinnamon-brown colour, closely sprinkled 
with small rusty scales, and conspicuously, though finely, striate longitudinally; tbe 
lowest primary spathe is larger than the others, has a limb about 18 cm. long, but 
in other respects is similar to the [others; tue partial inflorescences are elongate: 
the lowest and largest is 30 cm. long and bears distichally 17. branchlets or 
compound spikelets (in one specimen); the other partial inflorescences are gradually 
shorter and have fewer branchlets, but all, even the uppermost, bear secondary, 
although scantily flowered spikelets; secondary spathes elongate-infandibuliform, 10-20 
mm. long, loosely sheathing in their upper part, puberulous and finely striately veined, 
truncate, entire and finely ciliate at the mouth, prolonged at one side into a 
triangular acuminate point; the lower .and largest) branchlets are 7-8 em, long and 
carry distichally numerous (12—15), gradually diminishing secondary spikelets; the 
upper branchlets speedily decrease in length and number of spikelets; tertiary spathes 
(those of the compound spikelets) hairy-ramentaceous outside, membranous, shortly and 
broadly infundibuliform, entire, produced at one side into a spreading triangular acute 
point; spikelets very small, curved or subscorpioid: the largest, or those of the lower 
part of the branchlets, 5-6 mm. long, with 4-5 very approximate flowers, at 
most; the uppermost spikelets with 3-4 flowers only in all; spathels closely - 
packed, membranous, bracteiform, deflexed, concave, broadly ovate, acute, strongly 
striately veined; involucre calyculiform and apparently formed by two broadly ovate 
acute, strongly striately veined bracts, which are connate by their bases and adnate 
laterally to the axis of the spikelet, Male flowers seen only in the very young 
state; the calyx strongly striately-veined. Other parts unknown.

(Buitenzorg Herbarium). | 
OnsERVATIONS.— Known only from the male spadix, but it is obviously a near ally 
of €. bacularis, distinguishable from that by the more rigid and more regularly and 
densely panieulate spadix; by the primary spathes having a rigid, erect, entire, 
elongate ear-like limb; and by the male flowers having a strongly striately veined 
calyx. !
