 times 2-lobed. Ovules 2 in each cavity, pendulous. Drupe various. Seeds solitary or 

 rarely 2. Testa membranous. Endosperm fleshy. [Forestiem Foir.]

1. Adelia angustifolia (Torr.) Kuntze. An evergreen, often large shrub, with gla- 

 brous foliage. Leaves firm-leathery, 1-2.5 cm. long; blades linear to linear-cuneate, 

 obtuse, entire, revolute, lustrous above, not reticulated beneath, sessile : flowers often per- 

 fect, in small clusters : drupes ovoid, acute, short-pediceled. 



In dry soil, southern Texas and adjacent Mexico. Spring. 



2. Adelia segregata (Jacq. ) Small. An evergreen shrub, with glabrous foliage. 

 Leaves thin-leathery, 1.5-5 cm. long ; blades oblong-lanceolate, or spatulate, obtuse, slightly 

 revolute, lustrous above, finely reticulated beneath, narrowed into short petioles : flowers 

 from the branchlets of the previous year : drupes oval or ovoid, 7-8 mm. long, short- 

 pedicelled : stone longitudinally many-ribbed. \_Myrica segregata Jacq.] 



In dry woods and sand, peninsular Florida and the Keys. Also in the West Indies. Spring. 



3. Adelia pubescens (Nutt. ) Kuntze. A shrub, with widely branching stems and 

 densely hairy twigs. Leaves deciduous, 1-4 cm. long ; blades elliptic-oval or oblong- 

 obovate, obtuse, somewhat serrate, narrowed into short petioles : flowers from_ the branchlets 

 of the preceding year, the pistillate in clusters in short spurs, slender-pedicelled : drupes 

 oblong, 6-7 mm. long, the pedicels somewhat shorter : stone ribbed. 



On river banks, Arkansas to Florida and Texas. Spring. 



4. Adelia ligustrina Michx. A shrub 1-3 ra. tall, with widely branched stems, the 

 twigs and leaves pubescent, or glabrate in age. Leaves becoming firm, deciduous, 1-4 cm. 

 long ; blades elliptic, oblong, oval or approaching obovate, finely serrate, obtuse or acute, 

 manifestly petioled : flowers from the branchlets of the preceding year ; staminate in 

 numerous dense sessile clusters ; pistillate in clusters on very short spurs : calyx minute : 

 drupes nearly sessile, broadly oblong or oval, 7-8 mm. long. 



On river banks and in damp soil, Tennessee to Georgia and Florida. Summer. 



5. Adelia parvifolia (A. Gray) Small. A glabrous shrub 2-3 m. tall, with much- 

 branched stems. Leaves 1-4 cm. long, deciduous ; blades firm, oblong, elliptic or spatulate,
