Ü. tonkinensis. ] BECCARL MONOGRAPH OF THE GENUS CALAMUS. 975. 
subdiscoid, almost. explanate ; involucre also scale-like, asymmetric and almost explanate ; 
areola 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 pertanth 
shortly pedicelliform, the calyx callous at the base, divided down almost to the 
middle into 3 broadly triangular lobes; the segments of the corolla ovate-acute 
nearly twice as long as the calyx, Fruit small, ovoid; conic at the summit «ni 
very young (not seen mature); scales in 18 series, straw-yellow at the base, 
broadly bordered by reddish-brown; the margins narrowly scarious and finely erosely 
toothed, convex and not channelled along the middle (at least in the very youn 
fruit). uin 
llasrrar,—Collected by Faber in China (lower?). Herb. Vindob. 
OBSERVATIONS.—This seems allied to C. Walkerit, from which it differs in the leaf- 
rachis armed only with claws, and in the more elongate spadices with more numerous 
smaller and more diffuse partial inflorescences. Very few species of Calamus have the 
corolla of the female flowers so conspicuously longer than the calyx as in this species. 
The exact locality where this species was collected is not stated on the label accom- 
panying the specimen in the Herbarium Musei Palat. Vindobonensis. 
Prats 99.—Calamus Faberii Becc. The summit of a leaf (upper surface); portion 
of the spadix with entire partial inflorescences bearing immature fruit,—These parts 
constitute Faber’s type-specimen as seen by me in the Herb. Vindob.

sheaths . . . « . Leaves (not seen entire) apparently rather large, quite glabrous; 
petiole . . « « * 3 rachis in the intermediate portion subtrigonous, acutely bifaced. 
and smooth above, slightly convex beneath, where armed with straight, 10-15 mm. 
| long, slender deflexed spines, which have a fuscous tip and a light base and leave a. 
deep impression above them; leaflets apparently numerous and equidistant, 2°5 cm. 
apart on one of the sides of the rachis and 3:5 on the other side, opaque, pale-greenish 
or sub-glaucescent when dry, concolorous on both surfaces, papyraceous, rigidulous,. 
narrowly ensiform, 20-40 em. long, 18-19 mm. broad, somewhat narrowed to the base — 
and from the middle upwards gradually acuminate into a sparingly bristly-spinulous tip ;. 
this slightly indented on its lower margin, very distinctly 3-costate with another rather 
strong nerve near each margin and therefore sub-5-costate; on the upper surface the 
3 main costae of about the same strength, the central one naked and the side ones. 
furnished with a few short bristles from the middle upwards; underneath the costae 
are naked and. not very conspicuous; margins very uppressedly and inconspicuously 
spinulous; transverse veinlets fine not very crowded, much interrupted.. Male spadiz 
Ei ‘ Female spadiz partially supradecompound, apparently very large and with 
many partial inflorescences ; primary spathes tubular, closely sheathing, thinly coriaceous, 
one of the lowest -spathe somewhat flattened, striate longitudinally, two-edged (the 
edges spinulous), decayed and brittle at the summit (not fibrous or filamentose); the 
axial portions between two partial inflorescences elongate, subcylindraceous or slightly 
flattened more or less armed on the outer side with solitary or 3-nate claws; partial
