VIBUEMJM TEBNATUM, Eehd. 



VlBUBNUM TEENATUM, 71. Sp. 



Leaves in whorls of three or on the weaker branches opposite, membranaceous, elliptic to 

 oblong-obovate, acute or short-acuminate, cuneate at the base, entire, from 8 to 22 centimetres 

 long and from 4 to 9.5 centimetres wide, yellowish green and glabrous above, lighter green and 

 glabrous below with the exception of the long appressed hairs on the midribs, and on the five 

 to seven pairs of veins curving and anastomosing before reaching the margin and connected 

 by prominent transverse veinlets ; petioles slender, from 2 to 5 centimetres in length, pubescent. 

 Corymbs sessile, loose, from 12 to 17 centimetres in diameter, sparingly pubescent ; rays six or 

 seven, elongated into scorpioid cymes with umbel-like ramifications, the central ray the shortest ; 

 flowers sessile or short-pedicellate, on raylets from the second to the sixth order; calyx-tube 

 obconical, scarcely 1 millimetre long, glabrous, the lobes very minute and indistinct, ciliate; corolla 

 rotate-campanulate, yellowish white, about 5 millimetres in diameter, the lobes semiorbicular, 1.5 

 millimetres long, about equaling the tube ; stamens much exceeding the corolla, from 6 to 7 

 millimetres long ; anthers oval, yellow. Drupe red, oval-oblong ; stone oval-oblong, from 6 to 7 

 millimetres long and nearly 4 millimetres broad, grayish white, with a groove on the ventral side 

 and two shallower grooves on the dorsal side; seed punctulate, reddish brown. 



A shrub, from 1.5 to 4 metres high, with grayish brown branches, and appressed-pubescent

Viburnum ternatum is most nearly related to Viburnum sambucinum, Blume, which is easily distinguished from it by 

 its coriaceous leaves and pedunculate inflorescence. It is remarkable for its very compound inflorescence, and for the 

 three-whorled leaves. I should have considered the latter character an individual teratological aberration, if two spe- 

 cimens from different localities did not agree in this respect, while a third specimen shows a dissolved whorl, having one 

 leaf directly below the inflorescence and the two others only a little farther down. The weaker branches have opposite
