angled or -lobed; stipules none. Flowers white, monoicous: staminate flowers in racemes 
(ours) or panicles, without pistil, 10—20 in a cluster (ours): pistillate flowers solitary 
or in the same leaf-axil as the staminate, without stamens in ours. Calyx campanulate. 
Corolla rotate, 6—8 mm. wide (ours). Stamens in ours 3, mostly monadelphous. 
Ovary prickly, ours 2—4-celled; placentae 2. Fruit small, egg-shaped, opening by 1—2 
pores or lids, ours fleshy and becoming dry. Seeds |—-several. (Gk. echinos—=a hedge-

bud. Stamens 5, usually free from the corolla, distinct. Ovary inferior; style |; stigmas 
mostly 2—-5. Fruit a capsule (ours) or berry, prismatic or terete, often oblong or longer, 
2—5-celled, opening by terminal or lateral pores, or bursting irregularly. Seeds many, 
small. 
A. Stem-leaves lanceolate or spatulate to linear, petioled or sessile, not clasping.
