480 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [ C. conirostris 
broadly triangular teeth; the corolla slightly longer than the calyx. Fruiting 
perianth pedicelliform. Fruit ellipsoid, shortly conically beaked, 9-10 mm. long including 
the perianth ; 5-6 mm. broad; scales in 15 series with a very obtuse and round 
» point, shining  vernicose, very faintly channelled in their basal part, straw. 
yellow with a vivid red-brown intro-marginal line, margin very narrowly scarious, 
erosely toothed. Seed ovoid, apparently jdeeply and coarsely pitted (not seen perfectly 
mature).

OxsseRvations.—@. dimorphacanthus is closely related|'to €. siphonospathus and €. miero- 
carpus and differs from both in the leaflets with the mid-costa alone bristly above 
and in the more ellipsoid fruit with very shining scales rounded at the apex, which 
are also rather conspicuously bordered with a vivid reddish-brown band. 
€. dimorphacanthus was originally described by me from Vidal’s sterile specimens 
distributed with No. 3956 and taken from very young plants; ; my specimen has 
the sheathed stem 7-8 mm. in diam. and the leaflets are 10 mm. long; in the speci- 
men at Kew the leaflets are only 5 cm. in length, Another sterile specimen is 
preserved in Martius’s Herbarium at Bruxelles and was collected by Haenke. The 
leaf-rachis of these specimens bears some very long, very slender pale spines inter- 
mingled with the shorter one. In full-grown plants the long spines are not so 
numerous or are wanting, as they apparently give place to more robust spines. I have 
chiefly described Loher’s specimens in the Kew Herbarium ; Elmer's ones are more 
robust, and in these the leaves are terminated by a robust and strongly clawed 
cirrus; the leaflets are very rigid, 20-23 cm. long, 9-10 mm. broad, with rather 
long rigid bristles on the  mid-costa above, the cilia on the margins rigid, sub- 
spinescent, rather approximate and spreading; the leaf-rachis armed with robust 
digitate claws; the fruit 10 mm. long (not quite mature). In Loher’s specimen the 
leaflets are 17 cm. long and 7 mm. broad at most, and the fruit also immature, 9 
mm, in length.

DzscgiPTION.—Scandent, of moderate size, 6-7 m. high, Sheathed stem 2*5-3 cm. 
in diam.  Leaf-sheaths (sometimes flagelliferous? ) obliquely truncate at the mouth, 
gibbous above, very powerfully armed with very unequal, spreading or somewhat 
deflexed, scattered, light-coloured, polished, laminar, long acuminate spines, of 
which some are 2-5 cm. in length and 2-5 mm, broad at the base, and others much 
smaller, irregularly intermingled with the larger ones; those near the mouth much 
narrower and longer (up to 10-15 cm. in length) a cioulet, Straight, erect, recalling
