 Viburnum venulosum, Bentham, Fl. Hongkong, 142 (1861). 



Leaves coriaceous, persistent, elliptic to elliptic-ovate or rarely oval, acute or shortly acuminate 

 at the apex, narrowed at the base, entire or furnished with a few remote teeth near the apex, more 

 or less distinctly three-nerved by the greater development of the lowest pair of veins, dark 

 green, glabrous and lustrous above, lighter green, glabrous and dotted beneath with minute black 

 glands, and from 4 to 9 centimetres long, with three or four pairs of primary veins anastomosing 

 before reaching the margins, impressed on the upper surface, prominent on the lower surface 

 and connected by distinct transverse veinlets ; petioles nearly terete, from 5 to 10 millimetres long, 

 glabrous or rarely furnished with a few scattered hairs. Corymbs terminal, umbelliform, glabrous, 

 from 4 to 5 centimetres in diameter, nearly sessile, or on quadrangular peduncles not exceeding 

 1 centimetre in length ; rays usually five, the central one the shortest, furnished with glabrous 

 linear-lanceolate caducous bracts ; flowers on rays of the third order, sessile ; ovary ovoid, glabrous 

 like the semiorbicular calyx-teeth ; corolla rotate, glabrous, about 4 millimetres in diameter, the 

 suborbicular lobes scarcely longer than the tube ; stamens slightly exceeding the corolla ; anthers 

 broadly oval ; style short and thick, slightly exceeding the calyx-lobes. Drupe red, globose-ovoid, 

 crowned by the persistent calyx ; stone much compressed, about 6 millimetres high and 5 milli- 

 metres broad, concave on the ventral side, convex on the dorsal side. 



A glabrous shrub, with grayish brown branches, and pale yellow quadrangular branchlets, 

 becoming in their second year reddish brown, lustrous, and nearly terete. Winter-buds with two 

 pairs of scales. 



China: Hongkong, C. Ford, C. Wright; Anwhei and Kwangtung (ex Hemsley); Yunnan, 

 Szemeo, altitude 1600 metres, A. Henry (No. 12753). 



The Yunnan specimen collected by Henry differs from the type of Viburnum sempervirens in the presence of scattered 

 fasciculate hairs on the inflorescence, petioles, and on the under side of the midribs of the leaves ; but as the specimen does 

 not otherwise differ from Viburnum sempervirens, and as a few scattered hairs occnr on the petioles and inflorescence 

 of Wright's specimen from Hongkong in Herb. Gray, the Yunnan plant can hardly be considered a different species.
