A stout evergreen shrub ; branches smooth. Leaves very variable, 2-6 by ^4 in., 

 very coriaceous, polished above, usually obtusely caudate-acuminate, base acute obtuse 

 or even cordate, nerve-axils eglandular ; petiole - in. Cymes subsessile or on a 

 short peduncle, ^-1 in., sometimes puberulous. Calyx truncate or obscurely toothed. 

 Corolla campanulate, tube ^-5- 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. 



VAR. lanceolata, Thw. mss. ; leaves narrowly elliptic-lanceolate obtuse 4-5 by f-lg- 

 in. Canthium lanceolatum, Am. 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. 



VAR. grandifolia, Thw. Enum. 152 ; leaves very large 6-8 by 3-4 in., base rounded. 

 Ceylon. 



VAR. Kingii ; leaves more membranous elliptic-lanceolate very finely acuminate, 

 cymes deflexed corymbiform, flowers large, corolla-tube ^ in. quite glabrous. 

 Sikkim, Dr. King. This may prove a different species, but in the absence of fruit 

 this is uncertain. 



2. C. montanum, Thw. Enum. 152; unarmed, glabrous, leaves small 

 orbicular or ovate obtuse, cymes shortly peduncled subumbellate, flowers 5- 

 merous. 



CEYLON; central province, alt. 4-7000 ft., Thwaites. 



Probably, as Thwaites suspects, a small-leaved form of C. didymum. The fruit is 

 unknown. 



3. C. umbellatum, Wigl\t Ic. t. 1034 ; unarmed, glabrous, leaves elliptic 

 obtuse or obtusely acuminate, flowers umbellate on a short very stout com- 

 pressed peduncle, flowers 5-merous, fruit \-^ in. broad oblong or subquadrate 

 didymous, putamen rugose. Dalz. $ Gibs. Bomb. Fl. 113 (not of Korth.}. 0.
