€, pallidulus.] BECCARI, MONOGRAPH OF THE GENUS CALAMUS. 447 
In the Botanic Garden of Buitenzorg this seems a species which has spread 
out amongst the others, as | have received it with 5 different numbers and different 
localities and none from the Moluccas; one is said to come from Timor. In a 
confined space it is very difficult to keep the species of Calamus distinct when they 
are cultivated close together, as their seeds fall to the soil and germinate promis- 
cuously, and the more invading species take the place reserved for the others.  - 
Prate 199.—Calamus albus, Pers,-— The base of a leaf with portion of its leaf- 
sheath; two leaflets with portion of their rachis, this seen from the upper surface; 
portion of the cirriferous summit of a leaf; portion of a fruit spadix; spikelet with 
almost mature fruit; seeds.—From a plant cultivated at Buitenzorg, Herb. Bece. 
170. Catamus PALLIDULUS Becc. in Hook. f. Fl. Brit. Ind. vi, 457 and in 
Rec. Bot, Surv. Ind. ii, 211, 
Derscriprion.-—Rather slender or of moderate size, Sheathed stem 13-20 mm. in 
diam. Leaf-sheaths (not flagelliferous?) very thick, coriaceous, greenish or light straw- 
coloured (as almost every other part of the plant though dry) armed like the 
base of the petiole on its back with short strong spines which rest on a broad 
and swollen base. Leaves with a short (30-40 cm. long) pinniferous part and 
lengthened out into a rather long and robust cirrus; petiole very short or 
almost obsolete; rachis and cirrus strongly armed beneath with uniform, black- 
tipped, 3-fid claws; leaflets very few, 4-5 on each side, inequidistant but 
not aggregate, light yellowish-green when dry, rigid, pergamentaceous, paler beneath 
than above, elongate-ensiform, tapering towards the base, gradually or even rather 
suddenly narrowed at the summit into an elongate naked (not hairy or bristly) 
tip; the lower ones distinctly callous at their insertion, 20-25 cm. long, 15-20 mm. 
or occasionally 30-35 mm. broad and then lanceolate, with the mid-costa acute 
and the side nerves slender; all nerves naked on both surfaces; transverse 
veinlets rather distinct, especially above; margin remotely spinvlous. Male 
spadiz . . . . . Female spadiz diffuse, not flagelliform, relatively large (not 
seen entire); primary spathes tubular-cylindraceous, 7-8 cm. long, slightly enlarged 
above, and slightly narrowed towards the base where flattish on the inner side, 
thinly coriaceous, closely sheathing, truncate, entire and densely ciliate-paleaceous at 
the mouth, where shortly prolonged at one side into a triangular acute point, armed 
with rather numerous, scattered, very small, light-based black-tipped claws; the first 
not differing from the following; partial inflorescences rather approximate (about 10 
em. apart), spreading, inserted above the mouth of their own spathe with a distinct 
axillary callus; those seen by me 20-35 em. long with 5-8 distichous spikelets on 
each side and terminating in a very short slender tail-like unarmed appendix . 
secondary spathes tubular and slightly ivfundibuliform, 2-25 cm. long, truncate 
and densely ciliate-paleaceous at the mouth where shortly extended at one side into a 
triangular, patent, acute point, sparsely aculeolate, especially near the summit and 
on the outer side and further more or less covered with small adpressed ferrugineous 
tufts of hair which rest upon small asperities of the surface; spikelets inserted just 
at the mouth of their respective spathe with a distinct axillary callus, slightly
