C. floribundus] BECCARI, MONCGRAPH OF THE GENUS CALAMUS; 198 
bud; its anthers versatile, sagittate; the rudimentary ovary formed by three subulate 
rather elongate bodies. Female spadiz as the male but simply decompound, with few ; 
remote partial inflorescences which are 15-30 cm, long, and with 4-8 spikelets on 
each side; primary and secondary spathes as in the male spadix, scaly-furfuraceous 
when young, ultimately subglabrous; spikelets  vermicular, slightly arched, somewhat 
zig-zag sinuous between the flowers, the largest, the lowest, 8-12 cm. long, with 
12-16 bifarious rather remote flowers on each side; spathels furfuraceous, very 
broadly infundibuliform from a narrow base, truncate and entire at the mouth and 
prolonged at one side into a short triangular tip; involucrophorum sub-cupular with 
an acute tooth on each side, almost exserted from its own spathel and laterally 
attached at the base of the one above with a distinct supra-axillary callus; involucre 
eupular, usually emarginate on the side of the neuter flower, of which the areola is 
sublunate, rather deep and relatively large. Female flowers 4 mm, long, conic- 
ovate, acute; the calyx deeply 3-lobed, not or indistinctly striately voined outside; 
the corolla with lanceolate, acute segments as long as the lobes of the calyx; the 
stamens with filaments forming an urceolate tube crowned by 6 short teeth; the 
abortive anthers sagittate. Neuter flowers very similar to the fertile ones, but soon 
deciduous and thinner, with vacuous anthers and an abortive ovary formed by 
3 small acute bodies. Fruiting perianih explanate (not pedicelliform). Fruit almost 
spheric (subobovate when immature), suddenly beaked, 9-10 mm. in diam.; scales in 
15 series, obtuse, shining, superficially channelled along the middle, straw-yellow, 
bordered with a narrow brown-reddish line; margins finely erosely toothed. Seed 
suborbicular, rather convex, irregularly alveolate-suleate on the back, with a deep 
circular chalazal fovea on the flattish raphal side; albumen equable; embryo basal. 
Hasirat.—North-East India; Assam, Khasia Hills and Sylhet, (Wallich No. 8613), 
and (Hooker f. & Thomson in Herb. Kew). I have specimens from the Nambar 
Forest (G. Mann) and from the Charduar Forest (Brandis) in Assam; from the 
Khasia Hills (C. B. Clarke) at Sheelghat (100 m.) at Gowhatty (160 m.), and 
at Borlasa (1200 m.) It has been found also at the foot of the Mishmee 
mountains near Tapan Gam’s village in fruit in November (Grifith).—It grows. 
in the plains as well as on the hills, and it seems a rather common plant. 
Ossrrvations.—A. very variable plant in size, number of leaflets, and degree 
of armature of the different parts. It is very well characterised amongst the allied 
species by the few, grouped, relatively broad leaflets (with 3-5 costae, spinvlous 
above) and by the radiate arrangement of those of the terminal group. The young 
leaves of very robust plants are larger than those described above and may be 
mistaken for those of C. latifolius Roxb., but this has leaflets with smooth not 
spinulous nerves. 
Sometimes C, floribundus assumes very small dimensions, and seems almost a 
different species (see vAR. depauperatus). 
Prate 47.—Calamus floribundus Griff. Leaf-sheath with the. basal portion of 
a female spadix in flower and upper part of a leaf (on the right hand side) from 
Mann's specimens in H. Becc.; portion of a male spadix and two leaflets from 
Gowhatty (C. B. Clarke in H. Becc.); summit of a fruit-spadix, from Borlasa 
(C. B. Clarke). |
