2. REYNOSIA 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 latifdlia 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. Alsoin the Bahamas and West Indies. Spring. RED IRON-

nate, deciduous: blades leathery. Flowers perfect, very small, greenish white, solitary 
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, l-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. Condalia spathulata A. Gray. A rigid very spinescent shrub, with velvety 
ubescent twigs and young foliage, several dm. tall, diffusely branched. Leaf-blades spat- 
ate, 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 obovàta 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 
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.
