C. thysanolepis)  BECCARI. MONOGRAPH OF THE GENUS CALAMUS. 487 
these, 4 mm. long. Fruit obovate, suddenly and distinctly beaked, small (12 mm. 
long when not quite ripe). Fruiting perianth not pedicelliform, cleft into 6 lanceolate 
almost equal lobes; staminodes forming a ring more or less split and crowned by 
6 short triangular teeth; scales yellowish-brown with a broad intramarginal chestnut- 
brown line, faintly channelled along the middle; margins very narrowly scarious 
and erosulate. Seed not seen mature, but with equable albumen. 
Hasitat.—China; Yunnan on the  Szemao Mts. at about 1700 m. (Henry 
No. 12239 in Herb. Cale. ). 
OBSERVATIONS.—l have seen only a small portion of a leaf and of a fruiting 
spadix of this which, however, seems a species very distinct by its partial inflores- 
cences with spikelets adpressed to the axis of the spadix, decreasing in length 
from the base upwards and .not alternately distichous as is usually the case in 
almost ali other Calami. The flowers erect in the involucre and adpressed to the 
axis of the spikelets are of very rare occurrence. The neuter flower in the female 
spadix furnished with a very distinct and persistent pedicel on the areola of the 
involucre is also characteristic. C. Henryanus shows a certain affinity with C. 
leptospadiz.

Bot. Surv, Ind. ii, 216. 
DescripTion.—Stemless, erect. Leaf-sheaths apparently not tubular and gradually 
passing into the petiole. Leaves non-cirriferous, :8-1:2 m. long; petiole elongate, 
subterete, complanate; rachis in its intermediate portion trigonous, acutely bifaced 
above, roundish beneath, where armed along the middle with rather strong solitary 
claws; leaflets numerous, conspicuously clustered, 2 to 6 on each side being very 
approximate and almost in contact with one another and pointing different ways; the 
fascicles are usually opposite with long vacant spaces ( 5-10 em. long. ) interposed, yellowish- 
green on both surfaces, ensiform-acuminate with the mid-costa acute and one nerve 
stronger than the others on each side of it, all spinulous on the upper surface ; margins 
spinulous; the largest leaflets 37 cm. (15 in, Hance) long, those of an intermediate 
portion seen by me 30 cm, long, 15 to 20 mm. broad; the upper ones gradually 
smaller. Male spadiz..... Female spadiz not flagelliferous, unarmed, simply decom- 
pound with about 6 recurved partial inflorescences; primary spathes unarmed, loosely 
sheathing, furfuraceous, easily reduced into filaments; spikelets dense-flowered, about 
` T-b om. (3 in, Hance) long; spathels shortly  tubular-infundibuliform, prolonged 
at one side into a triangular acute point. Fruiting perianih distinctly pedicelliform. 
Fruit broadly ovoid-ellipsoid, shortly conically beaked, 15 mm. long; scales in 18 series, 
not channelled along the middle, reddish-yellow passing into reddish-brown towards tho 
apex, the margins finely ciliate-fringed. Seed ellipsoid, slightly flattened, subtubercled 
on the back, with a deep chalazal fovea on the raphal side; albumen equable; 
embryo basal.
