A stout evergreen shrub; branches smooth. Leaves very variable, 2-6 by 3-4 in., 
very coriaceous, polished above, usually obtusely caudate-aeuminate, base acute obtuse 
or even cordate, nerve-axils eglandular; petiole à in. Cymes subsessile or on a 
short peduncle, 1-1 in., sometimes puberulous. Calyx truncate or obscurely toothed. 
Corolla campanulate, tube dÄ in.; lobes 5, subacute. Style glabrous; stigma sub- 
quadrate, notched or 2-fid. Fruit very variable.—Thwaites var. rostrata is founded 
on the rostrate (that is caudate-acuminate) leaves, which, however, do not differ from 
those of a common Eastern or Western form; it has also often beaked elongate fruits, 
the result of insect injury. 
Van. lanceolata, Thw. mss.; leaves narrowly elliptie-lanceolate obtuse 4-5 by 2-13 
in. Canthium lanceolatum, Arn. Pugill. 24. Webera lanceolata, Moon. Cat. 19.— 
Ceylon, Thwaites.—Amongst Wight's duplicates (Kew Distrib. 1414) are specimens 
marked from Courtallam, but as none such are in Wight’s own Herbarium I suspect 
some mistake, 
Van. grandifolia, Thw. Enum. 152; leaves very large 6-8 by 3-4 in., base rounded. 
Ceylon. 
im Kingii; leaves more membranous elliptie-lanceolate very finely acuminate, 
cymes deflexed corymbiform, flowers large, corolla-tube 4 in. quite glabrous.— 
Sikkim, Dr. King.—This may prove a different species, but in the absence of fruit 
‘this is uncertain, 
9. C. montanum, Thw. Enum. 152; unarmed, glabrous, leaves small 
-orbicular or ovate obtuse, cymes shortly peduncled subumbellate, flowers 5- 
merous.

Probably, as Thwaites suspects, a small-leaved form of C. didymum. The fruit is 
unknown. 
3. C. umbellatum, ight Ic. t. 1034 ; unarmed, glabrous, leaves elliptic 
. obtuse or obtusely acuminate, flowers umbellate on a short very stout com-
