448 ANNALS OF THE ROYAL EOTANIC GARDEN, CALCUTTA. fC. macrospharlon. 
arched, spreading, their axis slightly sinuous, vermicular, cylindraceous, rather slender 
but rigid, the largest ones, the lowest, about 10 cm. long, with about 10 flowers 
on each side, the uppermost somewhat shorter;  spathels scabrid like the secondary 
spathes, but more densely, shortly tubular, slightly infundibuliform, entire, truncate 
and ciliate at the mouth, where shortly prolonged at one side into a triangular point; 
involuerophorum shallowly cupular, almost exsert from its own spathel and laterally 
attached to the base of the one above, posticously bidentate, involucre slightly 
exceeding the involucrophorum, shallowly cupular, almost entire; areola of the neuter 
flower depressedly lunate. Female flowers small, about 4 mm, long, rather remote, 
bifarious. Fruiting períanth pedicelliform, slightly ventricose and smooth at the 
base; teeth of the calyx broadly triangular; segmeuts of the corolla as long but 
narrower. Fruit (mature) spheric, 18 mm. in diam., tipped by a small mucro; 
scales in 15-18 series, rhomboid, broader than long, rather opaque, yellowish-brown 
shining, often very narrowly bordered with reddish-brown, and scarious at the 
margin, narrowly and superficially channelled along the middle, the point very 
slightly suddenly prolonged, obtuse. Seed globular-ovoid, 12 mm, long, very deeply 
and closely pitted all round; chalazal fovea indistinct; albumen deeply ruminate ; 
embryo subbasal. 
Hasrrat.—The Malayan Peninsula at Taiping (No. 2392) and at Simpang 
(No. 3017) in the district of Perak (Z. Wray, Herb. Mus. Perak); Singapore, 
(Ridley No. 6281). 
OsseRvATIOKS,— The description is taken from a portion of a spadix with imma- 
ture fruit (No. 2392) and a few mature fruits (No. 3017) and two leaves with a 
small portion of their sheath.  Ridley's specimen from Singapore consists only of a 
portion of the spadix with very young fruits which have more numerous scales, being 
disposed in 18 instead of 15 longitudinal series. 
Distinguished by its general light-yellowish colour when dry, in this respect 
recalling C. spathulatus. In the group it is moreover distinguishable by its leaves 
with a short pinniferous part, the elongate inequidistant smooth not fascicled leaflets; 
the scabrid secondary spathes and spathels. : 
Prate 200.—Calamus pallidulus, Bece. An entire leaf with a small portion of 
the sheath and lower portion of a female spadix with mature fruit; detached 
fruits and seeds;—from Wray’s specimen No. 3017, Herb. Perak. in Herb, Cale.

171. CALAMUS MACROSPHAERION Becc. sp. n. 
Description.—Apparently scandent and of large size.  Leaf-sheaths . . . . 
Leaves . . . . . Male spadiz . . . . . Female spadiz apparently rather large; 
the main axis in the small portion seen by me bears only one partial inflorescence 1 
em, thiek; upper primary spathes tubular, closely sheathing, thinly coriaceous, light 
greenish though dry, armed externally in their upper part with very small deflexed 
^ gubturbereuliform prickles; the partial inflorescence seen by me at first ascendent and 
then spreading, about 25 em. long, with 5 spikelets on each side; secondary spathes
