Stamens 6, more or less reduced or wanting in the pistillate flowers : filaments distinct : 
anthers 4-celled. Carpels 3-6. Ovary 1-celled : style or stigma subulate, entire. Ovule 
solitary in each cavity. Drupes somewhat flattened, with a more or less reniform or horse- 
shoe-shaped stone. Seed shaped like thestone. Embryo curved with flat narrow cotyledons. 
[ Cocculus DC.] CoRAL-BEAD. 
Foliage glabrate or merely puberulent: petioles much shorter than the leaf-blades. 1. C. diversifolia.. 
Foliage tomentose: petioles nearly as long as the leaf-blades. 2. C. Carolina. 
1. Cebatha diversifdlia (DC.) Kuntze. A glabrous or almost glabrous vine, with 
elongated stems. Leaf-blades leathery, varying from almost linear to oblong-ovate or ovate, 
acute or obtuse, more or less revolute, rounded or subcordate at the base; petioles much 
shorter than the blades : flowers yellowish ; staminate in leafy racemes ; pistillate in naked 
racemes: sepals eroded, the 3 outer ovate, 1 mm. long, the 3 inner broadly ovate, 2 mm. 
long : petals ovate-oblong, about 1 mm. long: drupe apparently purple, 6-7 mm. long.

2. Cebatha Carolina (L.) Britton. A vine, with trailing or climbing stems 0.5-3 m. 
long. Leaf-blades broadly-ovate or deltoid, 4-12 cm. long, entire or 3-5-lobed, tomentose 
beneath, deep green and glabrate above, rounded or cordate at the base ; petioles slender, 
somewhat shorter than the blades: flowers white ; staminate in compound racemes ; pistil- 
late in simple racemes : sepals 6, eroded, the 3 outer nearly oblong, 1 mm. long, the 3 inner 
oval, 2mm. long: petals 1 mm. long, eroded at the apex, auricled at the base : drupe red, 
7-8 mm. broad. [Cocculus Carolinus ( L.) DC.] 
In woods, fields and thickets, Virginia to Kansas, Florida and Texas. Summer. 
3. MENISPERMUM L. 
Perennial slender twining vines, woody below, herbaceous above. Leaves alternate : 
blades membranous, peltate, often palmately lobed, petioled. Flowers dioecious, white, in 
axillary panicles. Sepals 4-8, in 2 series. Petals 4-8, in 2 series, shorter than the sepals. 
Stamens 12-24, or reduced to 6 staminodia in the pistillate flowers: filaments distinct : 
anthers 4-celled. Carpels 2-4. Ovary 1-celled, sessile: stigma dilated. Ovule solitary. 
Drupe somewhat flattened, with a broadly reniform crested stone. Seed horseshoe-shaped. 
Embryo curved, with narrow cotyledons. MOooN-SEED. 
1. Menispermum Canadénse L. A finely pubescent vine, with twining stems 1-4 m. 
long. Leaf-blades orbicular to reniform in outline, 5-20 cm. broad, entire or 3-7-lobed, 
subcordate or cordate at the base, peltate near the base, glabrate above, the lobes rounded 
or short-acuminate ; petioles slightly shorter than the blades: flowers greenish white, In 
panicles: sepals oblong to oval, 1.5 mm. long: petals clawed, somewhat fan-shaped, the 
edges of the blade involute: stamens twice as long as the sepals: fruiting panicle resem- 
bling a bunch of grapes: drupes bluish black, 1 cm. in diameter. 
In thickets and along fences, Quebec to Manitoba, Georgia and the Indian Territory. Summer. 
FawiLY 6. CABOMBACEAE A. Gray. WATER-SHIELD FAMILY. 
Perennial aquatic caulescent herbs, with the foliage often mucilage-coated. 
Leaves alternate, opposite or whorled: blades various, those of submerged 
leaves often dissected, those of floating leaves peltate. Flowers perfect, incon- 
spicuous. Perianth of 2 whorls. Sepals and petals 3 or rarely 4 each, per- 
sistent. Androecium of 3-18 hypogynous stamens. Filaments slender. Anthers. 
usually extrorse. Gynoecium of 2-18 distinct carpels. Disk wanting. Ovary 
1-celled. Stigma sessile or nearly so, blunt. Ovules 2, on the sides of the 
cavity or the dorsal suture, or when 8, one near the ventral suture. Fruit several 
indehiscent nut-like carpels. Seeds 1-3, often 2. Embryo-at the base of the 
fleshy endosperm.
