per ones. Petals 4, apparently only 2 from the union of each of 
the lower to each of the lateral ones. Filaments 5, more or less 
united at the apex. Cells of the ovary formed by membranous 
projections of the placentee which occupy the axis of the ovary 
and are connected with its apex by 5 slender threads. Capsule 
often 1-celled by the disappearance of the dissepiments.

Shrubs or trees with simple or undivided leaves with sma! 
or no stipules and small, usually perfect regular flowers. Sep- 
als 4-5, united at base imbricate in the bud, usually persist- 
ent. Petals as many as the sepals and alternate with them, 
inserted by a broad base under the margin of the disk, imbri- 
cate in the bud. Stamens as many as the petals and alternate 
with them inserted on the margin or upper surface of the flat, 
fleshy disk. Ovary more or less immersed in and adhering to 
the disk, 2-5-celled with 1-several erect or ascending ovules in 
each cell. Styles and stigmas 2-5, distinct or combined into 
one. Seeds anatropous, often arilled. 
1. Euonymous. Flowers rather conspicuous, Ovary 3-5-celled: fruit 
colored: seeds in a bright red arill: deciduous shrubs. 
2. Pachystima. Flowers very small: ovary 2-celled: fruit small, not 
colored. Evergreen undershrubs.

Shrubs with 4-angled branches, opposite leaves with small, de- 
ciduous stipules and small flowers in axillary !—many-flowered
