VIBUBXUM LTTZONICUM, Rolfe. 



rnum luzonicum, Rolfe, Jour. Linn. Soc. xxi. 310 (1884). 



ives membranaceous, ovate, acuminate, rounded or broadly cuneate at the base, sinuate-dentate 

 and ciliate on the margins, dark yellowish green above and sparingly furnished with furcate hairs 

 most abundant on the veins, lighter green below and soft-pubescent with fasciculate hairs, par- 

 ticularly on the veins, from 4 to 6 centimetres long and from 2 to 3.5 centimetres broad, with from 

 five to six pairs of straight veins ending in the teeth ; petioles from 3 to 5 millimetres in length, 

 densely fulvous-pubescent. Corymbs terminal, short-stalked, from 3 to 4 centimetres in diameter, 

 densely fulvous-pubescent ; rays four or five of almost equal length ; flowers on rays of the 

 second or third order ; ovary ovoid, 1 millimetre long, densely fulvous-pubescent like the short 

 ovate calyx-lobes ; corolla rotate, from 4 to 5 millimetres in diameter, pilose outside, its lobes ovate, 

 longer than the tube ; stamens shorter than the corolla ; anthers oval, yellow ; style short, conical. 

 Drupe ovoid, red (not seen). < 



A slender-branched shrub, with densely fulvous-pubescent branchlets, becoming reddish brown 

 in their second season and nearly glabrous the following year. Winter-buds with two pairs of 

 scales.

This form differs from the type in the firmer chartaceous leaves glabrous above except on the midribs, less pubescent 

 beneath, and sometimes nearly glabrous at maturity, and in the less pubescent- branchlets and inflorescence. The drupe 

 is ovoid, red, crowned by the persistent calyx, with a stone broadly ovoid, pointed at the apex and truncate at the base, 

 much compressed, with three shallow ventral grooves and two very shallow dorsal grooves, 5 millimetres long and 4 

 millimetres broad. The branchlets often bear below the terminal corymb one or several pairs of corymbs on short 

 lateral branchlets.

The characters by which the Formosa plant differs from the type from the Philippine Islands do not seem to be 

 sufficient to separate it as a different species. From Viburnum dilatatum, Thunberg, however, with which Maximowicz 

 placed it, it differs in the smaller ovate leaves, the shorter stamens, the nearly sessile corymb, and the smaller flowers 

 and fruits. According to Dr. Henry, the savages of Formosa make bows of the wood.
