10. LETJCOTHOE D. Don. 



Shrubs, with terete branching stems. Leaves alternate, sometimes persistent : blades 

 entire or toothed, the teeth often bristle-pointed. Flowers perfect, in one-sided racemes.

 urn-shaped or cylindric, with 5 erect or spreading lobes. Stamens 10, included : filaments 

 adnate to the base of the corolla-tube : anthers often awned at the apex, opening by termi- 

 nal pores. Disk 10-lobed. Ovary 5-celled. Stigma entire, or 5-lobed. Ovules numer- 

 ous in each cavity. Capsule depressed, loculicidally 5-valved. 



Racemes from the axils of the persistent leaves of the preceding season : anthers awnless. 

 Filaments merely scabrous, nearly straight : anthers more or less manifestly bimucronate. 

 Twigs puberulent ; sepals imbricated. 



Larger sepals ovate : corolla 5-6 mm. long : leaf-blades mainly oblong. 1. L. axilUu-i*. 



Larger sepals orbicular-ovate : corolla 6-7 mm. long : leaf-blades mainly oval. 2. L. platyphytta. 

 Twigs glabrous : sepals not imbricated. 3. L. Catexbaei. 



Filaments pubescent, sigmoid-curved above: anthers pointless. 4. L. acuminate. 



Racemes terminal : leaves deciduous : anthers awned. 



Racemes curved : capsules manifestly lobed. 5. L. recurva 



Racemes straight or nearly so : capsules not lobed. 



Sepals %-% as long as the corolla, shorter than the capsules. 6. L. racemosa. 



Sepals about % as long as the corolla, surpassing the capsules. 7. L. elongata. 



1. Leucothoe axillaris (Lam.) D. Don. An evergreen shrub 1-2 m. tall, with 

 puberulent twigs. Leaf-blades leathery, oval, oblong or oblong-lanceolate, 4-15 cm. long, 

 acute or acuminate, rather remotely serrate, revolute, often sparingly pubescent beneath, 

 acute to rounded at the base ; petioles 0.5-1 cm. long : racemes axillary, 2-7 cm. long, 

 simple or compound : bracts broadly ovate, 2-3 mm. long, acute : pedicels 1-4 mm. long, 

 minutely pubescent : calyx 4-5 mm. broad : sepals ovate, 2 mm. long, acute : corolla white, 

 cylindric-ovoid, 5-6 mm. long : capsules spheroidal, 6-7 mm. broad. 



In damp woods and swamps near the coast, Virginia to Florida and Alabama. Spring. 



2. Leucothoe platyphylla Small. A straggling shrub 0.5-1 m. tall, with spreading 

 or drooping branches, the twigs and branches finely pubescent. Leaf -blades suborbicular to 

 oval, broadly oblong or oblong-ovate, 5-8 cm. long, abruptly pointed or slightly acuminate, 

 serrulate with very fine spinulose teeth, especially above the middle; petioles stout, 4-8
