those of both ends, except a few at tie base of the cirrus, are not much smaller. 
Male spadiz . . . Female spadiz inserted not far below the mouth of its leaf-sheath, 
small, erect, about 40 em. long, with only 5-6 alternate, simple, gradually 
reduced partial inflorescences; primary spathes closely sheathing, tubular, slightly 
enlarged, subinfundibuliform in their upper part, where they are rather densely 
beset with small prickles, very obliquely truncate at the mouth and produced 
into a long acuminate, membranous, erect point which subtends its respective partial 
inflorescence; the mouth of the leaf-sheaths is smooth or without spines; the lowest 
spathe very tightly sheathes the entire peduncular part of the spadix and is very 
similar to the upper ones, only somewhat larger, about 10 em, long, and like these 
carries a partial inflorescence: is strongly flattened, acutely two-edged, spinous 
on the edges, about 1 cm. broad above and only slightly less at the base; partial 
inflorescences erect with a conspicuous axillary callus: the lowest is about 15 em. long 
and carries 5-6 gradually reduced spikelets on each side; the other partial inflores- 
cences are gradually smaller and have fewer spikelets; secondarv spathes narrowly 
infundibuliform, obsoletely trigonous, scurfily hairy, truncate and naked at the 
mouths, produced at one side into a triangular dorsally-keeled point which subtends 
the base of the spikelets and is usually provided with a few relatively strong 
prickles on its keel; spikelets arched-subscorpioid, with the flowers in two not very 
regular series Of somewhat assurgent flowers; spathels short, broadly infundibuliform 
or at times so approximate and shallow as to become sub-bracteiform, also  scurifly 
hairy, shortly apiculate at one side or obtuse; involucrophorum laterally adnate to 
the base of the spathel above its own, very shallowly cupuliform; involuere orbi- 
cular, moulded on the involnerophorum, slightly concave or pateriform; the lowest 
spikelets are 6-7 cm. long and have 15-18 flowers on the whole, while the upper- 
most spikelets are only 15-20 mm. long and carry 5-6 flowers only; areola of 
the neuter flowers depressed, almost hidden under the edge of the involucre. 
Fruiting perianth pedicelliform, broader than high or somewhat depressed, the base 
of the calyx being thickened and enlarged, flat below and 4 mm. in diameter; from 
the remains the segments of the corolla appear broadly triangular and about as long as 
the calyx. Fruit spherical, 12-13 mm. in diameter (when quite mature), surmount- 
ed by a short but relatively large conical beak; scales arranged in 18 longitudinal 
series, considerably convex, glossy, narrowly and slightly grooved along the centre, 
of a light straw colour with a narrow blackish intra-marginal line extended 
to the rather obtuse appressed point; the margins very narrowly scarious and 
obsoletely and very minutely erosely toothed. Seed spherical, 9 mm. in diameter, 
minutely pitted; chalazal fovea punctiform; albumen rather deeply ruminated ; 
embryo basal.

OnSERVATIONS.—1t is related to OC. Jenningsianvs and allied species by the 
cirriferous leaves, the short spadices, the fruit with a pedicelliform perianth, and 
the ruminate seed. It is distinguishable by its narrow pluricostulate leaflets, by 
the very short spadix with subscorpiod spikelets and two series of subassurgent
