VIBURNUM PYRAMID ATTJM, Rehd. 



VlBUBNUM PYRAMIDATUM, n. sp. 



Leaves chartaceous, ovate-oblong to oblong, acuminate, narrowed at the base, denticulate-serrate, 

 dark green, glabrous and lustrous on the upper surface, light green and loosely covered with fas- 

 ciculate hairs on the lower surface, especially on the six or seven pairs of anastomosing veins, from 

 8 to 19 centimetres long and from 4 to 8 centimetres broad ; petioles 1.5 to 2.5 centimetres in 

 length, densely fasciculate-pilose. Corymbs terminal, pyramidal in outline, from 5 to 6 centime- 

 tres in diameter and about as high, consisting of three or four remote whorls of from four to six 

 rays, decreasing in size toward the apex ; peduncle from 2 to 4 centimetres long, densely yellow- 

 ish fasciculate-pilose like the rays ; flowers mostly on rays of the third order ; ovary cylindric, 

 glabrous, with ovate sparingly ciliate calyx-teeth about half as long as the tube ; corolla rotate, 

 about 4 millimetres in diameter, with ovate lobes; stamens slightly shorter than the corolla; 

 anthers oval ; style cylindric, exceeding the calyx-teeth. Drupe narrow-oblong, about 1 centimetre 

 long and from 4 to 5 millimetres broad, crowned by the persistent calyx, apparently dark red ; 

 stone compressed and slightly curved, with two deep grooves on the ventral side and one shallower 

 dorsal groove ; seed densely covered with red resinous glands ; albumen ruminate. 



A tree, 6 or 7 metres high, with terete branchlets furnished with fascicled and stellate yellowish 

 hairs, and becoming in their second year glabrescent and light grayish yellow. Winter-buds with 

 one pair of scales.

Viburnum pyramidatum is closely related to Viburnum lutescens, Blume ( V. sundaicum, Miquel), but is easily distin- 

 guished from that species by the pubescent branchlets and by the pubescence on the under surface of the leaves. In 

 foliage it also resembles the Himalaya Viburnum Colebrookianum, Wallich, but that species is very different in the 

 absence of the deep ventral furrows of the stone, in its solid albumen and lateral corymbs.
