also the localities of Makassar and Bouton in Celebes for C. barbatus, but I can 
hardly believe such a thing possible, as I do not know any species of Calamus 
inhabiting two such remote regions. 
OsseRvaTions,—A very distinct species not closely related to any other known to 
me. My description is based upon one of the type-specimens of Blume preserved at 
Leyden. Amongst the Papuan species it is distinguished by the spinous leaf-sheaths 
gradually passing into the petiole and densely covered near the mouth with brown 
erect rigid bristles; by the leaves with a short petiole and numerous inequidistant 
narrowly lanceolate subtricostulate leaflets, their 3 nerves bristly above, naked beneath; 
by the rigid short spadix with spathes which are densely bristly bearded at their 
mouth. 
Prate 87.—Calamus barbatus Zipp. The summit of a plant and portion of a ` 
partial infiorescence with immature fruit; from an authentic specimen preserved in 
the Herbarium at Leyden. 
72. CALAMUS vestitus Bece. Malesia iii, 59 and 62. 
. Drgcription.—Seandent, slender. Sheathed stem 12-15 mm, in diam. Leaf-sheaths 
flagelliferous, slightly gibbous or pouched above, with an obtuse slightly raised costa 
‘which runs downwards lengthwise from the base of the flagellum, and rather densely 
armed with small, short (5 mm. long at most), flat, delicate or almost bristly, 
deflexed, scattered, and occasionally bi-trifid spines.  Leaf-sheath flagella slender, filiform, 
densely armed with small, slender, solitary, geminate or ternate claws, Ocrea un- 
‘commonly large, completely enfolding or sheathing the younger part of the stem, 15-18 
em. long, very thinly membranous, and exsuccous, later lacerated and finely 
fibrous and ultimately destroyed. Leaves short (about 60 cm. long), not cirriferous, 
‘with the petiole almost obsolete; rachis flat in its first portion and  bifaced 
upwards above, rounded and unarmed beneath near the base and armed upwards 
along the middle with solitary rather slender claws; leaflets very numerous, equidistant, 
-closely inserted at a rather acute angle, thinly papyraceous but rigidulous, dull on both 
surfaces, slightly paler beneath, linear-ensiform, subulately acuminate at the summit, 
somewhat narrowed to the base, 3-costulate, or with an acute mid-costa and 
one distinct secondary nerve on each side of it, the 3 nerves furnished above with 
many dark and rather long bristles; beneath, all nerves faint and with a few 
bristles confined to the central one; margins very minutely and appressedly spinu- 
lous except at the point, where the spinules are longer and spreading; the largest 
leaflets, those of the lower third-part of the rachis, 20 cm. long and 10-12 mm, 
broad ; the uppermost suddenly a good deal shorter and less acuminate, the two 
of the terminal pair small and free at the base; transverse veinlets not very regular, 
much interrupted and very sharp. Male and female spadices very much the same, 
elongate-flagelliform; primary spathes very long-tubular and strictly sheathing, decayed 
and afterwards lacerated and fibrous at the mouth, fugaciously rusty-furfuraceous, 
rather densely armed with many very small solitary short black-tipped claws which 
have a broad and light-coloured base; lowest primary spathe somewhat compressed, 
‘not very acute at the edges, flattish and unarmed on the inner side, densely 
with the usual small slender claws on the back; the upper primary spathes
