d e s c r i p t i o n ) small, ovoid, apiculate, 12 mm. l o n g : scales in 18 series, of a very light

HABITAT.—Not uncommon in several parts of the Island of Hong-Kong, Hanee.
OBSERVATIONS.—1 have seen one of Hance's specimens, No. 18229 in St. Petersb.
H e r b . It seems allied to C. viminalis, but with equisdistant leaflets.

DESCRIPTION.—Apparently scandent and rather slender or of moderate size. Sie)}ia
n d leaf-sheaths Leaves ]iot ciiTiferous, a p p a r e n t l y about 1 m. long (only
t h e summit of one seen by me); petiole ; rachis in its terminal portion
a c u t e l y trigonous, bifaced above with acute and smooth upper angle, flat beneath
•where armed -with small approximate solitary dark-tipped claws; leaflets numerous,
e q u i d i s t a n t , rather approximate, firmly papyraceous, opaque and subconcolorous on
b o t h surfaces, linear-lanceolate, attenuated to the base, gradually acuminate to the
summit, with 3 distinct bristly costae above; beneath the mid-costa only with a few
l o n g bristles; transverse veinlets not v e r y approximate, short and much i n t e r r u p t e d;
t h e margins, especially the lower one, slightly thickened by a marginal nerve, minutely
a n d very appressedly spinulous ; the lowest leaflets of the apical portion of the leaf
seen by me (27 cm. in length and with II leaflets on each side) 22 cm. long,
17 mm. broad; the others rather speedily decreasing in length and less acuminatet
h e two of the terminal pair, the smallest, quite free at the base. Male spadiz
Female spadix simply decompound, elongate, flagelliform (apparently
fiagelliferous at its summit) with many remote partial inflorescences, and with the
a t t e n u a t e d part (base of the spathes) between two partial inflorescences rather
p o w e r f u l l y armed with solitary or more or less aggregate dark-tipped claws; upper
p r i m t i r y apatbes t u b u l a r , elongate, cylindraceous, very closely sheathing, more or less
prickly, t r u n c a t e or shortly split at tho mouth and slightly prolonged at the summit
i n t o a short triangular point ; partial inflorescences apparently rather numerous
n s e r t e d inside and issuing erect fi-om their respective spathe, rather rigid, pyramidal
i n outline, 12-18 cm. long with about 10 spikelets on each side; secondary spathes
cylindraceous, closely sheathing, unarmed, truncate at tho mouth and prolonged at
one side into a triangular very acute point ; spikelets inserted just at or a l i t t le
above the mouth of their own spathes, slightly arched, horizontal or deflexed
filiform ; the lower ones 5 - 6 cm. long with 12-13 flowers on each side, the others
speedily decreasing in length, those of the summit very short and with v e r y few
flowers; spathels cylindraceous at the base, rather suddenly expanded into a short
t r u n c a t e i n f u n d i b u l l f o rm limb, distinctly apiculate at one side ; involucrophorum

subdiscoid, almost e i p l a n a t e ; involucre also scale-like, asymmetric and almost e i p l a n a t e ;
a r e o l a of the neuter flower linear, depressed. Female flowers bifarious, small, about 3
mm. long, with the corolla almost twice as long as the calyx. Fruiting perianth
s h o r t l y pedicelliform, the calyx callous at the base, divided down almost to the
m i d d l e into 3 broadly t r i a n g u l a r lobes ; the segments of the corolla ovate-acute,
n e a r l y tvrice as long a s . t h e calyx. Fruit small, ovoid, conic at the summit when
T e r y young (not seen mature); scales in 18 series, straw-yellow at the baser
b r o a d l y bordered by reddish-brown ; the margins narrowly scarious and finely erosely
toothed , convex and not channelled along the middle (at least in the very young
f r u i t ) .
HABITAT.—Collected by Faber ia China ( l o w e r ? ) . Herb. Vindob.
OBSERVATIONS.—This seems allied to C. Walkerii, from wliich it difiers in t h e l e a f -
r a c h i s armed only with claws, and in the more elongate spadiijes with more numerous
smaller and more difiuse p a r t i a l inflorescences. Very f e w species of Calamus have the
corolla of the female flowers so conspicuously longer than the calyx as in this species.
T h e exact locality where this species was collected is not stated on the label accomp
