136 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [C. timorensis. 
lt is a very peculiar species for its subcirriferous leaves, elongate, non-cirri- 
ferous, caudiculate spadix and fusiform fruit, borne by a conspicuous campanulate 
fruiting perianth. 
SuPPL. PrarE 78.—Calamus longispathus Ridley, An entire spadix with not 
entirely mature fruits; lower portion of a leaf, upper surface. From Ridley’s 
No. 8777 in the Herbarium at Singapore. 
CALAMUS TIMORENSIS Becs, n. sp. 
Descartption.—Apparently scandent and rather slender. Sheathed stem 1T mm. in 
diameter.  Leaf-sheaths very obliquely truncate at the mouths, slightly gibbous above, 
densely armed with very finely subulate, very narrowly and thinly laminar, unequal, 
dark-coloured, spreading, elastic, rather dull or at least not glossy spines, 
often approximate by their bases set in transverse irregular series; the larger 
spines are 3-4 cm. long and 1-2 mm. broad at their bases, others are smaller and 
almost capillaceous; the surface of the sheaths is more or less superficially but very 
closely stamped with the impressions left by the spines during the prefoliation. and 
is dull and covered with a pulverulent darkish scurf in the interstices ; the ligule 
is triangular, about 15 mm. long, and densely hairy-hispid. Leaves apparently 
cirriferous, but in the specimen seen by me their upper end was wanting; petiole 
almost obsolete (1-2 cm. long); rachis glabrescent, irregularly set throughout and on 
both surfaces with small prickles, somewhat flattened and 6-7 mm. broad in its 
basal part, irregularly convex and obsoletely grooved at the sides higher up. Leaflets 
few, sub-equidistant but very distantly set on each side of the rachis (7-9 cm, apart), 
inserted at a rather wide angle, rather thinly papyraceous, dull and almost equally 
green on both surfaces, lanceolate, tapering from the middle down to an acute base 
and upwards to an acuminate and at the sides bristly apex: they are finely but 
rather sharply 3-costulate, also at times sub-5-costulate : on the upper surface the 3 
central costae are almost of equal strength and sprinkled with a few short bristles; 
the under surface is quite smooth; margins finely and appressedly ciliate-spinulous, 
especially at the apex; the intermediate leaflets are 23~24 em. long and about 3 
em. broad: those near the base slightly smaller (20 cm. by 2-2:5 em. 
Hasirat.—It was collected by Teijsmann in Timor (No. 10791 in Buitenzorg 
Herbarium. 
OBSERVATIONS.— The material upon which C.  /imorensis is established is very 
scanty and incomplete, not even sufficient to recognize its position among its 
congeners, but I have given to it a name in consideration of its being the only 
Calamus certainly known as growing in Timor. Moreover, by the assistance of the 
plate the species may be easily recognized, as it possesses some characters which 
I have not found in any other Calamus. It is in fact distinguishable by its dull, 
dark, scurfy leaf-sheaths, densely armed with seriate, long, and very slender laminar 
spines, and by the leaves being almost without a petiolar part, by - the rachis set 
with scattered prickles all round, and by the few, very remote, equidistant, lanceolate 
3-sub-5-costulate leaflets.
