e palembanicus. BECCARI. THE SPECIES OF CALAMUS.—SUPPLEMENT. 75 
branchlets is short (4-5 cm. long), terete, 5-6. mm. thick at its base, speedily 
narrowing and terminating in a spikelet; tertiary spathes thinly membranous, very briefly 
cyathiform, truncate and entire at the mouth, very slightly produced at one side, 
glabrous, finely striate, unarmed; spikelets sinuous, vermiform, terete, about 3 mm. 
thick in their axial part, and 7-9 cm. long, inserted just outside the mouth 
of their respective spathes, and carrying distichally 20-25 flowers on each side; 
spathels shortly infundibuliform, truncate and entire at the mouth, slightly produced 
at one side into short triangular points, finely veined; involucrophorum  shallowly- 
cupular, protruding slightly beyond its spa:hel, subpedicellate; involucre conspicuous 
orbicular, entire, concave, pateriform and quite on a level with the involucrophorum, 
areola of the neuter flower broadly ovoid, slightly concave, sharply edged, Female 
flowers 4 mm. long. Fruiting perianth explanate; the calyx has a smooth callous base 
and is deeply parted into 3 strongly striately veined lobes; the segments of the 
corolla are barely longer than the calyx, acute and also striately veined. Fruit ovoid, 
shortly and acutely beaked, 12 mm. long, 8 mm. broad; scales arranged in 21 longi- 
tudinal series, subsquarrose, very thin, rather dull, slightly convex, not or only very 
obsoletely convex along the centre, brown with a darker intramarginal line and finely | 
fringed ferrugineous margins, the point not produced, yet acate. Seed broadly ovoid, 
rounded at both ends, slightly excavate and with a broad rather deep central 
chalazal fovea on the raphal side, otherwise with a slightly uneven surface; albumen 
equsble ; embryo basal, slightly to one side. 
Hasirat.—Lower Tonkin: the portions of the spadix with mature fruits were 
bought in the market of Thanh hoa, on the 30th October 1892, by the Rev. Père 
Bon (No. 5743 in the Paris. Herb.-arium.) 
Oxservations.—Of this species I have seen only detached portions of a fruiting spadix, 
and from these I judge it to bs a rather large plant. It belongs to group XV(A), 
but apparently it is not closely related to any of the known species, except perhaps 
C. Scipionum. It is distinguishable by its short branches with very few, thickish, 
brachiate, sinuous, many-flowered spikelets, which have .a conspicuous saucer-shaped 
involucre; by the small fruit with subsquarrose, not grooved, ferrugineously fringed, 
scales; by the slightly unevenly surfaced seed with equable albumen, and embryo 
slightly shifted to one side, and by the laciniate secondary spathes,
