VIBUBNUM LOBOPHYLLUM, Geabn. 



ViTTTRmTM lobophyllum, Grabner, Engler Bot. Jahrb. xxix. 589 (1901). 



Leaves membranaceous, ovate to orbicular-ovate or sometimes broadly obovate, acuminate or 

 abruptly acuminate at tbe apex, rounded, truncate or rarely broadly cuneate at the base, dentate, 

 with shallow mucronate teeth, yellowish green and glabrous or sparingly hairy and pubescent 

 on the midribs above, lighter green and glabrous beneath, with the exception of sparse loosely 

 appressed hairs on the midribs and veins, from 6 to 11 centimetres long and from 4 to 8.5 centi- 

 metres broad, with six or seven pairs of straight veins, and transverse veinlets conspicuous beneath ; 

 petioles slender, from 1.5 to 3 centimetres in length, furnished near the base with two small some- 

 times caducous stipules. Corymbs terminal, from 5 to 10 centimetres in diameter, on peduncles from 

 2 to 3 centimetres long or occasionally shorter, and thinly and minutely pubescent and glandular 

 like the rays, or rarely glabrescent ; rays seven, slender ; flowers mostly on rays of the third order, 

 pedicellate ; ovary ellipsoid or nearly cylindric, about 1 millimetre long, glandular and usually 

 furnished with a few simple hairs ; calyx-lobes orbicular-ovate, ciliate or nearly glabrous ; corolla 

 rotate, 6 millimetres in diameter, the lobes orbicular-ovate, longer than the tube ; stamens exceed- 

 ing the corolla; anthers oval, yellow; style about twice as long as the calyx-lobes, cylindric. 

 Drupe subglobose, bright red, about 7 millimetres high ; stone flattened, suborbicular, rounded at 

 the base, pointed at the apex, and 5.5 millimetres high and broad, with one shallow ventral groove 

 and two shallow dorsal grooves. 



A shrub, with upright branches, and pale yellowish brown branchlets sparingly hairy when they 

 first appear, becoming glabrous and dark reddish brown at the end of their first year. Winter-buds 

 with two pairs of scales, glabrous, reddish brown.

 alto monte Thae-pei-san," August, 1899, G. Giraldi (Nos. 1467, 2555, 2556 in Herb. Florence) ; 

 Hupeh, A. Henry (Nos. 2885, 6250), E. H. Wilson (No. 900); Szech'uan, A. Henry (No. 8930). 



Viburnum lobophyllum is most nearly related to Viburnum Wrightii, Miquel, but differs from that species in the 

 longer petioles with stipules, the glandular inflorescence, and the cylindric style ; from the allied Viburnum betuli- 

 folium, Batalin, it may be distinguished by the shape of the leaves and their pubescent veins, the longer peduncles, 

 smaller corymbs, and by the shape of the stone. Of the flowering specimens, Henry's No. 8930, referred by Hemsley to 

 Viburnum dilatatum, Thunberg, agrees perfectly with the type in the shape of the leaves except that they are smaller, 

 while in the other flowering specimens the leaves are more or less distinctly ovate. 



The original description of Viburnum lobophyllum is somewhat misleading, as the leaves are described as three-lobed 

 or entire and crenate, but the leaves can hardly be called lobed or their margins crenate. The leaves which show the 

 nearest approach to being lobed are not different in shape from the broadly obovate leaves of Viburnum Wrightii, 

 Gray, and Viburnum dilatatum, Thunberg, in which the almost truncate or slightly sinuate apex is abruptly con- 

 tracted into the acumen.
