Small trees or shrubs, with tough flexible branchlets, naked or scaly buds, and fibrous roots. 
Leaves opposite or very rarely verticillate, petiolate, involute in vernation, entire, serrate or dentate, 
deciduous or persistent; stipules obsolete or minute, or conspicuous and rarely ample. Bracts and 
bractlets minute, lanceolate, acute, caducous. Flowers articulate with the short bracteolate or bibrac- 
teolate pedicels, white or rose color, in terminal or axillary umbel-like flat or panicled cymes, the cymes 
sometimes radiate with large neutral ray-flowers. Calyx-tube turbinate or sub-cylindrical, the limb 
short, equally five-lobed, persistent. Corolla tubular, turbimate or rotate, equally five-lobed, the lobes 
spreading and reflexed after anthesis. Stamens five, inserted on the base of the corolla alternate with its 
lobes, in one or rarely two series; filaments filiform or subulate, exserted, short or elongated ; anthers 
oblong, attached on the back below the middle, introrse, versatile, two-celled, the cells opening longi- 
tudinally. Ovary inferior, one or at first incompletely two to three-celled ; style capitate, conical, short, 
divided at the apex into three stigmatic lobes; ovules solitary, suspended from the apex of the interior 
angle of the cell, resupinate; raphe dorsal; micropyle superior. Fruit ovoid or globose, terete or 
compressed, one or incompletely two to three-celled, crowned with the persistent limb of the calyx and 
with the remnants of the style, dry or fleshy, the flesh sweet, acidulous, or oily; stone coriaceous, 
chartaceous or corneous, ovate or orbicular, flattened or globose, smooth or marked with longitudinal 
grooves or ridges. Seed oblong, compressed, concave on the ventral face or slightly winged or incurved 
Embryo 
on the margin; testa membranaceous, adherent to the copious fleshy or ruminate albumen. 
minute, near the hilum ; cotyledons ovate ; radicle terete, erect.’ 
1 Viburnum may be divided into the following sections : — MicroTinus. Flowers in paniculate cymes; corolla cam- 
Exterior flowers of the corymb neutral. 
Orutvus. Cymes radiate or uniform ; leaves deciduous, their 
panulate-rotate or salver-shaped; drupe imperfectly 
2-celled ; endocarp compressed, its margins incurved; 
petioles often biglandular at the apex, stipulate; buds 
naked or scaly ; fruit red or black, 1-celled. 
Flowers all perfect ; buds scaly. 
Lentraco. Flowers in terminal umbel-like cymes ; corolla 
rotate, funnel-form or tubular ; drupe 1-celled ; endocarp 
flattened ; albumen fleshy, homogeneous. 
Trnus. Flowers in umbel-like cymes ; corolla rotate ; drupe 
dry, 1-celled ; endocarp subterete ; albumen Tuminate ; 
leaves coriaceous. 
albumen fleshy, homogeneous. 
OREINOTINUS. Flowers in umbel-like cymes ; corolla cam- 
panulate-rotate ; drupe imperfectly 3-celled ; albumen 
fleshy, homogeneous. 
SoLENotTinvs. Flowers in paniculate cymes ; corolla tubu- 
lar, elongated, with a spreading limb; drupe imperfectly 
3-celled ; endocarp flattened ; albumen fleshy, homoge- 
neous.
