406 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [Q. latifolius. 
the inner side, more or less armed with short, scattered, straight, slightly deflexed 
spines; secondary spathes sparingly aculeolate, tubular-infundibuliform, obliquely 
truncate and entire at the mouth, prolonged at one side into a short point; spikelets 
arched, spreading, 3-5 cm. long, inserted just at the mouth of their own spathe 
not or slightly callous at the axilla, with 6-12 very approximate flowers on each 
side. Female flowers approximate, 4 mm. long. Fruiting perianth not pedicelliform, 
its calyx almost entirely split down to the base. Fruit broadly ovoid-ellipsoid, 15 
mm. long, 9 mm. broad, suddenly narrowed at the summit into a conic beak; 
scales as long as broad, rather opaque, almost flat, not or very indistinctly channelled 
along the middle, of a dirty straw colour with a dark shining chestnut-brown 
intramarginal band, which broadens towards the tip; this triangular, somewhat 
elongate, rather acute, not very appressed, its margins finely erosely toothed. Seed 
rounded at both ends, 6 mm. long, 5 mm. broad, convex and rather deeply pitted 
on the back, flattish and with an elliptic and rather deep chalazal fovea on the 
raphal side; albumen equable; embryo basal. 
Hasitat.—Camboja, prov. Ipong on the Kuang Repen mountains and in Lower 
Cochin-China on the Dinh mountains near Baria, Pierre No. 4847. _ 
Native names: “Ichuan” in the Kmer language and “May roup” or ‘ Mai 
tau” in Annam (Pierre). 
OnsERvATIONS.—-Distinguishable from the type by its smaller dimensions, the 
narrower leaflets and the female spikelets shorter; the fruit smaller and more 
globose; the scales with a slightly longer tip, Probably the leaf-specimens which 
accompany the fruit-spadices in Pierre’s Herbarium are from the lower part of the 
stem or from a young plant, as the rachis is armed with straight and not hooked 
spines—a fact which is of common occurrence in many species of Calamus. 
I should have been much inclined to refer to this variety of C. palustris the 
C. verus of Loureiro, whose description of the leaves corresponds sufficiently well, 
but that of the spadix is apparently of a Daemonorops.
