18% ANNALS OF. THE ROYAL BOTANIC GARDEN, CALCUTTA. [C. javensis. 
CALAMUS JAVENSIS var. PENINSULARIS, subvar, PINANGIANUS Becc. in Hook. f. Fl. 
Brit. Ind. vi, 443, and in Rec. Bot. Surv. Ind, ii, 201. 
^  DrscnrPrTi0N,— Sheathed stem 6 mm. in diam. Leaf-sheaths mottled with dark 
green and light patches and covered with numerous slightly deflexed spines of the 
usual form but with finer tip.  Leaf-sheath flagella with the lowest spathe aculeolate 
on the back. Leaves with the petiole very short almost obsolete; rachis more 
strongly aculeate than in the type; leaflets usually more or less evidently. 
clustered, rather narrow, lanceolate. acuminate, 15-18 em. long, 2°5-3 cm. broad, 
not spinulous on the carine; the two of the lowest pair inserted very near the 
mouth of the sheath, spreading (not deflexed). Male spadiz very long, the one seen 
with 3 partial inflorescences, of which the lowest, the largest, has 3 spikelets on 
each side and one at the apex, which is longer than the side ones; the other inflor- 
escence has 6 spikelets in all, and the uppermost only two. Male flowers 4 mm. long, 
cylindraceous, obtuse. 
Hasrrar.—Pulo Penang: collected by Mr. Curtis at an elevation of about 650 m, 
(Moniot’s Rd.) in Jan. 1886. : 
OssEkVATIONs.— lhe characteristic notes of this variety are: the mottled densely 
spinous and apparently not striate leaf-sheaths; the narrow subclustered leaflets, of 
which the two of the basal pair are not deflexed and do not embrace the stem.

Descriprion.—Sheathed stem 6-7 cm. in diam.  Leaf-sheaths longitudinally striate, 
rather densely armed with straight, flattened, subulate, horizontal or slightly defloxed 
spines which are swollen at the base and sealy-barbed at the margins when young, 
Ocrea 8-15 mm. long, more or less woolly-furfuraceous and with long cilia at 
the margins when young, finally brittle and falling to pieces. Leaflets few, 
oblanceolate, suddenly acuminate into a long tip, distinctly 3-costate (the costæ 
and nerves naked on both surfaces), the two of the terminal pair connate for 
two-thirds of their length, the two basal usually quite deflexed, concave and 
embracing the stem. Leaf-sheath flagella with the lowest spathe aculeolate on the 
back or smooth. Female spadiz with the primary spathes rather strongly aculeolate, 
especially at the npex; partial inflorescences with 3-4 spikelets, each 4-5 cm. long. 
Fruiting perianth almost entirely explanate under the fruit, its calyx subapiculate at 
the base. Fruit 12-13 mm. long (including the beak) ellipsoid-ovoid with rounded 
base and vertex, page by a cylindraceous or obscurely trigonous beak, this 1°5 mm. 
long and bearing the BONUS Ee eee ee Seed 1:5-8 mm. Ai with 
irregular rather concave facets.
