part ; they are very narrow, strictly and densely _ spiciform, composed of a few 
very appressed, small, few-flowered spikelets in their lower part, but from about 
the middle composed only of at first ternate, then geminate, and fina 
female flowers; secondary spathes and spathels similar, smooth, infundibul 
narrow bases, obliquely truncate at the mouths and ‘produced into a triangular 
erect, acute, marcescent point; the spikelets are inserted inside their own spathes ; 
-the lower and largest spikelets are 15-20 mm. long, and have two series of 5-6 
subunilateral, erect, appressed female flowers; involucrophorum and involucre similar, 
cupular, subcyathiform, truncate, obliquely evolute; the involucre on the side of the 
neuter flower is almost ear-like; areola of the neuter flower ovate, niche-like, sharply 
edged. Fruiting perianth explanate, Fruit globose, shortly beaked, about 1 cm. in 
diameter; pericarp very thin and brittle; scales broader than long, arranged in 21 
longitudinal series, straw-coloured, edged by a narrow, very dark band, very 
narrowly and faintly grooved along the centre, not produced, bluntish or subacute 
at the apex, the margins almost entire. Seed irregularly globular, 7 mm. in diameter, 
facetted: the facets slightly concave; chalazal fovea large and rather deep in the 
centre of the raphal side; albumen equable; embryo basai.

OBSERVATIONS.—1t is related to C. Henryanus, but is distinguishable by the 
shorter, very simple, distinctly spiciform partial inflorescence; by the areola of the 
neuter flower devoid of a special support for its flower; and by the leaves, which 
apparently have smaller leaflets, but those of C. .Henryanus are very imperfectly 
known. Like €. Henryanus it shows also a certain affinity to C. leptospadiz.

the Herbarium at Paris, Balansa No. 517. 
The specimen of a Calamus collected by J. Cavalerie in China at Ly-po, 
Province Kwei-tschou (Kouy-tcheou) 25°30 N. Lat., 108" E. Long. Gr., apparently 
is the male plant of C.  Balansaeanus. [I have seen of it only a spadix, and the 
apex of a leaf which corresponds iu every particnlar with the corresponding part 
of the type, only the leaflets are slightly larger. The spadiz is exactly like that 
of the female of ©. Balansazanus, about 1 m. long, and terminating in a very 
slender minutely clawed flagellum; it bears 6 small, gradually decreasing, very 
narrow and strict partial inflorescences, of which the lower ones are composed 
of very few (2-5 in all) side spikelets, and of one terminal which is considerably 
larger than the others; the upper inflorescences are reduced to this single elongate 
spikelet; the secondary  spathes are very narrow, angular, closely sheathing, 
produced above to a triangular acuminate point; the lateral spikelets are 
2-25 cm. long, flattened and with 5-10 flowers on each side; the terminal spikelet 
of each inflorescence is 6-7 cm. long, with more or less approximate flowers; spathels 
very obliquely infundibuliform, covered with small rusty  ramentaceous scales, 
produced at one side to a triangular acuminate and bristly tip; involucre deep, 
subcalyciform, deeply emarginate and bidentate on the side next to the axis. Mak 
flowers 4-5 mm. long, lanceolate-acuminate, obsoletely trigonous; the calyx is 
‘scarious-membranaceous and gradually narrows above, has a small opening with 3 
very small teeth at its apex, otherwise it is entirely closed; the corolla is
