2. RBYNOSIA Griseb. 



Unarmed evergreen shrubs or trees, with rigid branches. Leaves opposite : blades 

 leathery, entire, emarginate : stipules small, caducous. Flowers perfect, very small, yellow- 

 ish green, in sessile axillary umbel-like clusters. Hypanthium hemispheric, persistent. 

 Sepals 5, valvate spreading. Disk fleshy, filling the hypanthium. Petals wanting. 

 Stamens 5, inserted on the margin of the disk : filaments subulate, incurved, shorter than 

 the sepals : anthers introrse. Ovary almost superior, 2-3-celled : styles short, thick, 

 united : stigma 2-3-lobed. Ovules 1 in each cavity, erect. Drupe tipped with base of the 

 style, with a thin fleshy pulp and a crustaceous stone. Seed solitary, with a thin, rugose, 

 tuberculate testa. Endosperm ruminated. 



1. Reynosia latifolia Griseb. A slender evergreen tree, reaching a maximum height 

 of "about 9 m., with a trunk sometimes 20 cm. in diameter, clothed with a reddish brown 

 scaly bark. Leaf -blades firm, oblong, varying to ovate or obovate, usually retuse at the 

 apex and sometimes mucronate, entire, glabrous, short-petioled : flowers several together 

 in axillary clusters : pedicels 4-5 mm. long : calyx 5 mm. broad ; sepals 5, triangular or 

 ovate-triangular, longer than the hypanthium, acute : stamens 5, shorter than the sepals : 

 drupes subglobose, oval or obovoid, 1.5-2 cm. long, purple or nearly black, edible. 



Near the coast, Florida and the Keys. Also in the Bahamas and West Indies. Spring. RED IRON-

 or clustered in the axils. Hypanthium broadly turbinate. Sepals 5, persistent, valvate, 

 spreading. Disk fleshy, filling the hypanthium, slightly 5-angled. Petals wanting. Sta- 

 mens 5, or rarely 4, inserted on the margin of the disk : filaments incurved, shorter than 

 the sepals : anthers introrse. Ovary almost superior, 1-celled or imperfectly 2-3-celled : 

 styles stout, united : stigma 2-3-lobed. Ovules solitary, nearly erect. Drupe tipped with 

 the remains of the style, with a thin fleshy pulp and a crustaceous stone. Seed flattened or 

 subglobose, with a thin smooth testa. Endosperm thin. 



Leaf-blades 5-12 mm. long : stigma 2-lobed : drupes 4-5 mm. long. 1. C. spathulata. 



Leaf-blades 12-25 mm. long : stigma 3-lobed : drupes 6-8 mm. long. 2. C. obovata. 



1. Coiidalia spathulata A. Gray. A rigid very spinescent shrub, with velvety 



Eubescent twigs and young foliage, several dm. tall, diffusely branched. Leaf-blades spat- 

 ite, elliptic or oblong, 5-12 mm. long, varying from acute and apiculate to retuse, entire, 

 short-petioled, at length glabrous : flowers greenish white, one or several in the axils : 

 calyx becoming glabrous, about 2 mm. broad ; sepals 5, triangular, about as long as the hy- 

 panthium : petals wanting : stamens 5, shorter than the sepals : drupes obliquely ovoid or 

 obovoid, 4-5 mm. long. 



On plains and prairies, middle Texas to New Mexico and northern Mexico. Spring. 



2. Condalia obovata Hook. A spinescent shrub or small tree, reaching a height of 

 about 10 m., with finely pubescent twigs and young leaves, the bark pale gray : leaf- blades 

 obovate varying to broadly spatulate, attenuate to the base or cuneate, entire, rounded, 

 truncate or retuse and mucronate at the apex or rarely acutish, at length glabrous, with a 

 prominent midrib, short-petioled : flowers greenish white, solitary or 2-4 in axillary clus- 

 ters : calyx glabrous or nearly so, 1.5 mm. broad : sepals triangular, about as long as the 

 hypanthium : petals wanting : stamens 5, shorter than the sepals : drupe subglobose, 6-8 

 mm. in diameter, black, sweet to the taste. 



In dry soil, central and southern Texas and northern Mexico. Spring. BLUEWOOD. LOGWOOD. 

 PURPLE HAW. 



4. ZIZYPHUS Juss. 



Spinescent shrubs. Leaves alternate, mostly 2-ranked : blades firm, 3-nerved : one or 

 both of the stipules commonly spine-like. Flowers greenish, in axillary cymes or umbel- 

 like fascicles. Hypanthium broadly turbinate. Sepals 5, triangular, keeled on the upper 

 side, valvate. Disk obscurely 5-lobed, nearly flat. Petals 5, alternate with the sepals, 

 hood-like, at first surrounding the stamens. Stamens 5, inserted with the petals at the edge 

 of the disk : filaments subulate : anthers introrse : sacs opening lengthwise. Ovary 2-3- 

 celled, nearly immersed in the disk : styles 2-6 : stigmas terminal, or lateral on the inner 

 faces of the styles. Ovule solitary, erect. Drupe sometimes berry-like, fleshy, the stone 

 horny. Testa thin, membranous, smooth.
