VIBUEOTM BETULIFOLIUM, Batal. 



Viburnum betulifolium, Batalin, Act. Hort. Petrop. xiii. 371 (1894). 

 Viburnum Willeanum, Griibner, EngUr^ot. Jahrb. xxix. 589 (1901). 



Leaves deciduous, ovate to rhombic-ovate and from 3 to 6 centimetres long and from 2 to 4 

 centimetres broad, or rarely elliptic-oblong and from 6 to 8 centimetres long and from 2 to 4.5 

 centimetres broad, acute or short-acuminate, broadly cuneate at the base, coarsely dentate except 

 the lower third, with four or five pairs of straight veins, glabrous and dark green on the upper 

 surface, lighter green and glabrous on the lower surface with the exception of a few simple hairs 

 on the veins ; petioles slender, from 1 to 1.5 centimetres in length, sparingly hairy or glabrous, 

 furnished near the base with two small stipules. Corymbs terminal, umbelliform, from 6 to 10 

 centimetres in diameter, on peduncles from 1 to 2 centimetres long, or occasionally shorter, and 

 glabrous or slightly hairy ; rays usually seven, sparingly covered with short fascicled hairs or 

 sometimes nearly glabrous; flowers on rays of the third and fourth order; ovary glandular and 

 sparingly hairy ; calyx-teeth minute, broadly triangular, ciliate ; corolla rotate, glabrous, scarcely 

 5 millimetres in diameter, the lobes orbicular-ovate, longer than the tube; stamens exceeding the 

 corolla ; anthers oval, yellow ; style short, conical, scarcely exceeding the calyx-lobes. Drupe red, 

 subglobose, about 6 millimetres high ; stone compressed, 3.5 millimetres high and 3 millimetres 

 broad, with three very shallow ventral grooves and two equally shallow dorsal grooves. 



A shrub, with glabrous branches, and branchlets purple or purplish brown during their first 

 and second years, later becoming marked by longitudinal fissures. Winter-buds with two pairs 

 of scales.

Viburnum betulifolium seems most closely related to Viburnum Wrightii, Miquel, but differs chiefly in the pre- 

 sence of stipules, in the more coarsely serrate ovate or rhombic-ovate leaves, with fewer veins, and in the glandular and 

 hairy ovary. The type specimens of Viburnum betulifolium do not differ in the least from the type of Viburnum 

 Willeanum. 



As Mr. Wilson collected mature seeds of this species, plants of it are probably now growing in the Veitchian nur- 

 series near London. As an ornamental shrub Viburnum betulifolium will probably be as valuable as Viburnum Wrightii, 

 and, like that species, will doubtless be a handsome object in flower and in fruit
