 reddish brown bark. Leaf-blades spatulate or cuneiform, frequently ovate or 

 obovate on the shoots, 2-4 cm. long, 1-3 cm. broad or larger on vigorous 

 branches, cuneate or contracted at the base into margined petioles, acute or 

 bluntly pointed at the apex, irregularly serrate and incised, glabrous when 

 fully grown, or with tufts of pale hairs in the axils of the principal veins 

 beneath: corymbs 2-5-flowered, simple: pedicels, hypanthium and lanceolate 

 sepals glabrous: corolla 15-18 mm. broad: stamens 15-20, the anthers purple: 

 fruit globose or subglobose, 8-10 mm. in diameter, orange-red when ripe: 

 nutlets 3-5, 4-6 mm. long, the hypostyle 3-4 mm. long.

 shoots, acute or bluntly pointed at the apex, narrowed or abruptly contracted 

 at the base, irregularly serrate and often with acute or blunt shallow lobes, 

 glabrous or with tufts of pale hairs in the axils of the veins beneath: corymbs 

 compound, many-flowered, glabrous: corolla 10-14 mm. wide: stamens normally 

 20: fruit globose or subglobose, 4-7 mm. in diameter, red or orange-red when 

 ripe: nutlets usually 5, the hypostyle three-fourths as long as the ventral angle.

7. C. paludosa Sarg. A small tree 4-5 m. tall, with gray or reddish brown 

 bark, or more frequently a large shrub with several stems and spiny branches.

 cm. long, 7-30 mm. wide, mostly acute at the apex, cuneate, contracted or on 

 the shoots rounded at the base, glabrous or with tufts of pale hairs in the 

 axils of the veins beneath, serrate, occasionally cleft or incised, especially on 

 vigorous shoots: corymbs several-many-flowered: stamens about 20, the anthers 

 purple: fruit subglobose or short-oval, 5-8 mm. in diameter, red or orange-red 

 at maturity: nutlets 3-5, the hypostyle three-fourths the length of the ventral 

 angle.

8. C. subviridis Beadle. A tree 6-8 m. tall, with gray bark. Leaf-blades 

 ovate, obovate or oval, 2.5-6 cm. long, 1-4 cm. wide, or larger on the shoots, 

 acute or acuminate, rarely rounded at the apex, contracted or narrowed at the 

 base, or on the shoots rounded and truncate, glabrous or glabrate when fully 

 grown, the borders serrate and incisely lobed: corymbs compound, many- 

 flowered, pilose-pubescent: pedicels and hypanthium sparsely pilose: sepals 

 narrowly lanceolate, entire or minutely serrate, pubescent on the inner surface, 

 at least at flowering time: corolla 12-15 mm. wide: stamens normally 20: 

 fruit globose, 5-7 mm. in diameter: nutlets 3-5, about 5 mm. long, the hypo- 

 style three-fourths as long as the nutlet. 



In low woods and on banks of streams, near Chattahoochee. (Endemic.) 



9. C. contrita Beadle. A tree sometimes 6-7 m. tall, with ashy gray or 

 brownish scaly bark, or more frequently a large shrub with spreading branches. 

 Leaf-blades ovate, oval or oblong, rarely short-obovate or suborbicular, 2-5 

 cm. long, 1.5-5 em. broad, glabrous at maturity, acute or bluntly terminated 

 at the apex, rounded or contracted at the base, the borders serrate and incised ; 

 petioles 5-20 mm. long, margined: corymbs simple, glandular-bracteate, 3-7- 

 flowered: pedicels and hypanthium glabrous: sepals 3-5 mm. long, glandular- 

 serrate: corolla 12-17 mm. wide: stamens 20, the anthers dark purple: fruit 

 subglobose, 7-9 mm. in diameter, at maturity yellow-green or orange, often 

 with ruddy cheeks, the flesh firm : nutlets 2-3, rarely 3-5, about 6 mm. long, the 

 hypostyle occupying a trifle more than half of the ventral angle.
