SiKKiM HiMAiATA, alt. 1,500 ft., at Sittong, King; Khasia and Jyntea Mis., De 

 Silva; Westehn Peninsula, from the Concan southwards; Malayan Peninsula, 

 from Mergui southwards ; Ceylon, common. — Distrib. Malay Archip., S. China. 



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

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

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

 short peduncle, j-1 in., sometimes puberulous. Cal^x truncate or obscurely toothed. 

 Corolla campanulate, tube ^g-^ 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-1 J 

 in. Canthium lanceolatum, Am. Ptigill. 24. Webera lanceolata, Moon. Cat. 1.9. — 

 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. grandifoUa, 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. montanuxn, 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. didynam,. The fruit is 

 unknown. 



3. C. umTjellatum, Wight le. t. 1034 ; unarmed, glabrous, leaves elliptic 

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

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

 didymous, putamen rugose. Dalz. §• Qihs. Bomh. Fl. 113 {not of Korth.). 0.
