426 RUBIACE Æ. CANTHIUM. 
not fall off, nor is the stigma composed of two distinct plates, as in Richard's 
generic character of Psydrav, probably derived from his other species from 
Madagascar, and which perhaps ought still to be removed from Canthium. 
t * 1302. (2) C. nitens (DC.:) unarmed, glabrous: leaves petioled, broadly 
ovate, somewhat obtuse, upper side very shining: racemes compound, axil- 
lary, many-flowered, a little longer than the petiole: tube of the corolla a 
little longer than the lobes; lobes oval, obtuse: stamens 4: stigma thick, - 
ovate, much protruded.— DC. prod. 4. p. 474. 
Collected by Leschenault in India, but perhaps not in the Peninsula: if 
however it be so, we suspect it must be an accidental tetrandrous form of 
C. didymum, a plant which otherwise does not appear to have been ever seen 
by A nega although occurring in various parts through which Leschenault 
travelled. 
1303. (3) C. parviflorum (Lam. :) shrubby, usually with opposite horizontal 
thorns a little above the axils, sometimes with the branches nearly unarmed: 
leaves ovate, glabrous, often fascicled on the young shoots: racemes short, 
; few-flowered : stamens 4: stigma somewhat globose, often more or 
less bifid or marked with a longitudinal furrow: drupe obovate, slightly 
emarginate, compressed, furrowed on each side.— Lam. enc. meth. 1. p. 602 ;

, The size of the leaves and length of the petioles and thorns are very va- 
riable. The structure of the flower is by no means alike in all: in some spe- 
cimens the calyx-teeth are oblong, somewhat foliaceous and recurved; the 
tube of the corolla short, and the segments very woolly inside, the stamens 
scarcely exserted and hidden by the wool of the throat, style longer than the 
tube, stigma capitate and 2-lobed: in others the calyx-teeth are small ovate 
and pointed, the tube of the corolla longer and less woolly and its segments 
glabrous, anthers exserted, style longer than the tube, stigma capitate entire 
longitudinally with a sharp angle between the grooves: but although 
nces may be constant among specimens taken from the same 
bushes, we are not prepared to assert that they are sufficiently so, sp
