184 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [C. javensis 
and not callous at their insertion. Male spadiz l-l:3m. long, with 3-4 partial 
inflorescences, each of which bears 8-10 spikelets. Female spadiz exceedingly slender, 
filiform, the one seen about 60 cm. long with only one partial inflorescence, 
which bears 2-3 spikelets 15 mm. long, otherwise agreeing in the minute 
characters of the flowers and their involucres with those of the typical form, 
peduncular portion of the spadix sheathed by three spathes. Fruiting  perianth 
almost entirely explanate under the fruit. Fruit ovoid-ellipsoid, more elongate and 
more conspicuously beaked than in the type, 1 cm. long without the 3 mm. long 
beak, and 7 mm. in diam.; scales in 15 series, almost flat or slightly con- 
cave, narrowly channelled along the middle, the margins pale, the tip marked 
by a transverse dark line, Seed more elongate than in the type, its facets 
slightly concave.

OssERVATIONS.— This seems to be the alpine form of €. javensis (form 
peninsularis ), corresponding to the variety ezilis of the Javan form. It differs from 
the type in the exceedingly slender stem; in the spines of the leaf-sheaths having 
a tendency to change into claws; in the small number and narrowness of the 
- leaflets; and in the long-beaked elongate fruit. 
PLATE 39.—Calamus javensis var, tenuissimus Bece. Portion of the plant with 
a leaf and an entire male spadix, from Scortechini’s No, 236 ^**, in Herb. Beco.; 
another portion of the plant with a fruiting spadix from Scortechini’s No. 648 *s, 
in Herb. Beccari. 
CALAMUS JAVENSIS var. SUBLAEVIS Becc. 
Description.—Sheathed stem 7-3 mm. in diam. Leaf-sheaths green, almost 
polished, distinctly striate longitudinally, smooth or with very few short straight 
spines. Leaves 45-80 cm. long with a petiole sometimes very long (as much as 30 
em.); leaflets inequidistant, 4-6 on each side. Ocrea elongate, smooth, finally brittle 
and deciduous. | 
HasrrAT.— Borneo; at Kutcing on Mt. Mattang (Beccari P. B. No. 1694). 
OssERvATIONR.— The very scantily armed or almost smooth leaf-sheaths distinguish 
this variety from tetrastichus. I have two leaves of it, the one with the petiole 
5 cm. long, the other more than 30 cm., probably because the latter leaf belongs 
io a young shoot. 
PLarE 40.—Calamus javensis var. sublevis Bece. Portion of the stem with a 
leaf (on the right-hand side) from P, B. No. 1694 in Herb. Beccari.

DrscRrPrION.—S/e5 more robust than in the type.  Leafsheafhs rather densely 
covered with straight, horizontal, 5-6 mm. long spines. Leaves with relatively
