214 ANNALS OF THE ROYAL BOTANIC GARDEN,. CALCUTTA. [C. mollis 
an acute and sometimes dentieulate border.. Female flowers very small, about 3 mm. 
long; the calyx obconic-campanulate, narrowing at the base, divided. down. to: the 
middle into 3 broad acute lobes; corolla one-third longer than the calyx, divided 
into 3 lanceolate acute segments; the stamens united by their bases and forming a 
very high membranous urceolum which is crowned by 6 broad triangular acute 
teeth, of which 3. appear amongst the segments of the corolla and simulate an 
additional whorl of the corolla; the anthers sterile, sagittate at the base, obtuse at 
the apex. Fruiting. perianth not pedicelliform,  explanate. Fruit ovoid-elliptie or 
subobovate, small, about 1 cm. long, 6 mm. thick, very suddenly contracted into a 
rather long beak; scales in 16 series, faintly channelled along the middle, light 
greyish-yellow, sometimes indistinctly spotted at the apex, with paler erosely toothed 
margin. Seed very small, 4-5 mm. long, somewhat flattened and very irregularly 
angular with an indistinct chalazal fovea; albumen equable; embryo basal.

Osservations.—I have described the male plant from the specimens collected by 
Gandichaud at Manilla and seen by Martius, and the fruit from the No. 12506 of 
Warburg in the Herbarium at Berlin. 
I am not quite certain that the Calamus named by Martius C. mollis is really 
that published by Blanco under this name, but in the absence of authentic specimens 
of the true C. mollis, I have followed Martius, Furthermore this author has considered 
as belonging to C. usitatus Blanco, a partial inflorescence with immature fruit of 
C. mollis also collected by Gaadichaud at Manilla (Herb. Deless.) and therefore 
apparently Martius has given the name of C. mollis to the male plant and of C. 
usitatus to the female one of the same species. C. usitatus has been identified by 
me with Demonorops Gaudichaudi. 'The arrangement of the leaflets in ©. mollis is 
very variable, as in some leaves they are almost equidistant, with only very few 
spaces between the leaflets slightly larger than usual, while at other times these 
spaces are rather long and very variable, chiefly towards the apex of the leaf 
which then looks very much like that of C. Blarcoi, ein 
Vidal’s No. 1939 in the Kew Herbarium belongs to a more robust form than 
the type specimens of Cuming and Gaudichaud; one of its partial male inflorescences 
being 30 cm. long, rather compact, with many secondary branchlets charged with 
numerous 4 em. long spikelets, C. mollis: is characterised as follows:— Rather slender 
leaf-sheaths sparingly spinous; leaves short, petiole very" short, leaflets narrowly 
lanceolate, not very numerous, inequidistant but not fascicled, narrowly lanceolate 
uni-costate or  sub-2-costulate; spadices flagelliform, spikelets ` with. very. elónoly
