C. discolor] BECCARI. MONOGRAPH OF THE GENUS CALAMUS. | 495 
OssERVATIONS.—l 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 ©. heteracanthus, 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 cuneate at the base. Its 
affinities are doubtful, but perhaps they are with the species of group XII.

Descrrprion.—Non-scandent ? Leaf-sheaths 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.)

Osservations,—C. Lindeni has been described and figured from a living young 
plant, but it is easy to recognise in it C. discolor of Martius, known also from 
sterile specimens only. Two leaves preserved in the Herbarium at Kew and 
labelled: “ Philippines. Ex. Herb. Veitch 1897” entirely correspond to the descrip- 
tion of Martius and to the plate quoted above, except that the leaflets are smaller 
and more numerous, 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 
blackish bristles; the leaflets are numerous (65 in one leaf), equidistant, rather 
approximate, narrowly lanceolate, 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 
subiri-costulate above or with the mid-costa rather acute and one slender nerve on 
cach side 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 asaut, remoíe, 
much inte rrupted ; margins very minutely and adpressedly spinulous.
