nute or almost none: flowers deep yellow, in elongated spicate racemes: pod subglo- 
bose or oval, glabrous.—Extending from Arkansas and Indian Territory into north- 
ern and eastern Texas. 
2. SOPHORA L. 
Trees, shrubs or herbs, with unequally pinnate leaves, small or obso- 
lete stipules, terminal or axillary racemes, 10 distinct stamens, and a 
terete (or somewhat compressed) thick or coriaceous mostly indehis- 
cent several-sceded stipitate necklace-like (constricted between the 
seeds) pod. 
* Herbaceous perennial. 
1. S. sericea Nutt. Silky-canescent, erect, 30 em. high or less: leaves with subu- 
late stipules and numerous small oblong-obovate leaflets 6 to 12 mm. long: flowers 
white: pods few-seeded.—Only recorded west of the Pecos, but doubtless in north- 
western Texas as well. 
** Shrubs or trees. 
9. S. tomentosa L. Shrub 12 to 18 dm. high, hoary-tomentose: leaflets 11 to 17, 
oblong, coriaceous, becoming smooth above: showy yellow flowers in elongated ra- 
cemes: calyx minutely 5-toothed: pod 10 to 15 em. long, glabrate.—A species of the 
West Indies and Florida found in the vicinity of Brazos Santiago. 
3. §. affinis Torr. and Gray. A small tree, 3 to 6 m. high, nearly glabrous: leaf- 
lets 13 to 15, elliptical, retuse or very obtuse, mucronulate, less than 2.5 cm. long, 
nearly the same color both sides: flowers in simple axillary racemes: calyx very 
short, campanulate, abruptly attenuate at base, obscurely 5-toothed: pod somewhat 
pubescent.—Extending from Arkansas into Texas as far south as the valley of the 
San Antonio and west as far as the upper Colorado. 
4. S. secundiflora Lag. (FRIJOLILLO. CoRAL BEAN.) A stout shrub or small tree, 
with deep green leaves of about 9 elliptical-oblong obtuse coriaceous leaflets, termi- 
nal.racemes of showy violet fragrant flowers, and large woody pods 5 to 10 cm. long, 
containing 3 or 4 round red beans as large as small marbles and very poisonous.— 
Common .from the Gulf coast to the Pecos and less abundant in mountain cafions to 
New Mexico. It is mostly shrubby, but becomes a tree 30 feet high and forms groves 
in the vicinity of Matagorda Bay. The beans are sometimes used by the Indians as 
an intoxicant. The flowers are variously described as ‘‘ sweet-scented, exhaling the 
odor of violets,” and as “giving off a strong, nauseating, and very offensive smell.” 
3. CROTALARIA L. (RATTLE-BOX.) 
Annuals, with simple or 3-foliolate leaves, racemes of yellow flowers 
opposite the leaves, a 5-cleft (scarcely 2-lipped) calyx, a large heart- 
shaped standard, monadelphous stamens with 5 of the anthers smaller 
and roundish, and an inflated pod. 
* Leaves simple and scarcely petioled. 
1. C. sagittalis L. Hairy, 7.5 to 15 cm. high: leaves oval or oblong-lanceolate ; 
stipules united and decurrent on the stem, so as to be inversely arrow-shaped: pe- 
duncles few-flowered: corolla not longer than the calyx: pod blackish.—The common 
“ pattle-box ” of sandy soils in the Atlantic and southwestern States, and also found 
in Mexico, hence presumably of more or less abundant occurrence in Texas. 
* * Leaves 3-foliolate and long-petioled : corolla comparatively large: keel with a con- 
spicuous horizontal beak. 
2. C. lupulina DC. Glabrous or nearly so, diffuse: leaflets ovate, oblanceolate, 
or obcordate ; stipules minute, deciduous: racemes few- flowered : pod short, oblong, 
sessile, puberulent, 12 to 16 mm. long.—Along the southern boundary of Texas, from 
Brazos Santiago to El Paso.
