494 ANNALS OP THE EOYAL BOTANIC GARDE^-, CALCUTTA. [C. Hatimannt
HABITAT.—British New Guinea, where discovered on the F l y River in 1890 by
Sir Willia7n Macgregor.
OBSERVATIONS.—1 have seen of this only the upper portion of a loaf ( which was
60 CUI, in length ) and 3 detached partial inflorescences. It is difficult to point out
t h e affinitie.s of this species, almost all New Quiuean Calami being very imperfectly
known. Uharacteristics of this species are the slightly inequidistaut, elongate,
3-costulate leaflets; the short and rigid partial inflorescfincos with npikelets inserted
through a distinct and long pedicel inside their respective spathes; iind the fruit
with very light-coloured, nairowly chaunclled and strongly gibbous scales.
I n the spikclets with a pedicelliform part included in their respective spathes
and in the non-cirriferous leaves this approaches the species of group II.

DEscRiPTiOif.—Non-scandent. Siem as thick as a walking cane, 2-5-.3 metres high.
Leaf-sheaths Leaves non-cirriferous, in one specimen about 60 cm. long
including the petiole, this 15 cm. in length, obtusely trigonous, striate, glabrous,
opaque, slightly arched, very narrowly channelled along' the middle on the uppeisurface,
feebly tu-med beneath ( a n d in its lower part also at the very obtuse
margins ) with weak, hooked prickles; rachis almost from tbe base bifaced with a
rather acute and smooth salient angle abore, roundish, unarmed and striate beneath;
leaflets not very numerous, U on each side in one specimen, with a bilobed
terminal one, inequidistaut, usually approximate in couples on eacti side with short
vacant spaces interposed, papyraceous, rather finn, glabrous and aubconcolorous on
b o t h surfaces, very slightly paler beneath, narrowly oblong or oblauceolate tapering
lower down towards a rather acute base, very suddenly contracted at the summit
into a snort, acuminate, bristly-spinulous tip, slightly concave convex, finely and
acutely S - i - c o s t u l a t e with a few secondary nerres interposed; all nerves naked
on both surfaces and rather distinct also in the lower one; transverse veinlets very
sharp, very approximate and continuous across the b l a d e ; margins very remotely
and inconspicuously epinulous; the largest leaflets, those near the summit, It cm.
l o n g , 3 cm. broad, more con cave-con v e s than the o t h e r s : the terminal cuneatoly
narrowed towards the base, formed by two connate midway up: the lower ones
g r a d u a l l y smaller: the smallest, the lowest, 4 cm. long, 8-10 mm. broad.—Other
p a r t s unknown.
HABITAT.—British New Guinea. Collected by Mr. C. J l . Uarlmrmn in 1887 and

OBSHIVATIONS.—I have seen of this only a leaf, which apparently belongs to a
non-scandent plant, being very sparingly prickly on the petiole and quite smooth on
the rachis : furthermore it is distinguishable by its oblong geminate suddenly
apiculate leaflets, with very numerous approximate and continuous transverse veinlets,
as in the species of the group of C. heieracatithus, and with 3-5 slender costae—
naked and distinct on both surfaces—^and by the terminal leaflet deeply bilobed (being
formed by two highly connate leaflets) and gradually cunoate at the base. Its
affinities are doubtful, but perhaps they are with the species "f group X I I.

C. Lindenii Rodigas, Illustr, Hort, xxx ( 1883 ), ir)7, t. CCCCLXXXIX.
DESCRIPTION.—Non-scandent? Leaf-shaaths open on the ventral side, densely
armed with long straight broad-based brown spines. Leaves non-cirriferous; leaflets
numerous, equidistant, lanceolate, acuminate, narrowing towards the base, dark green
above, nearly white beneath. (Descript. from Rodigas.)
HABITAT.—The Malay Archipelago.
OBSERVATIONS.—C. Lindenii has been described and figured from a living young
plant, but it is easy to recognise in it C. discolor of J l a r t i u s , known also from
sterile specimens only. Two leaves preserved in the Herbaiium at Kew and
l a b e l l e d : " P h i l i p p i n e s . Ex. Herb. Veitch 1 8 9 7 " entii-ely correspond to the descript
i on of Martius and to the plate quoted above, except that the leaflets ai-e smaller
and more nuinerous, but perhaps this is only a difference depending on age. The
two leaves are narrowly oblong-elliptic in outline, 75-80 cm. long including a
petiolar portion ; this about 20 cm. long, roundish and like the rachis densely
rusty-furfuraceous and armed with feeble straight unequal solitary horizontal short
acicular spines ; in the upper surface the rachis is provided also with scattered
b l a c k i sh bristles ; the leaflets ate numerous ( 6 5 in one leaf ), equidistant, rather
approximate, narrowly lanccolate, almost equally narrowed towards both ends, rather
shortly acuminate at the summit, all, except a few at the extremities, of about
the same size, 12-13 cm. long, 12-13 mm. broad, thinly papyraceous, green and
subtri-costulate above or with the roid-costa rather acute and one slender nerve on
each sido of it furnished with a few long blackish bristles, conspicuously
covered with a very tenuous crustaceous white indumentum beneath, where the
mid-costa is very minutely bristly spinulous ; transverse veinlets distinct, remote,
much interrupted; margins very minutely and adpressedly spinulous.
