1. GC. maritima Scop., var. ZQUALIS Chapman. Stem much branched and pros- 
trate; leaves oblong, irregularly toothed or pinuatifid, narrowed into a petiole: pods 
linear, 8-ribbed, the upper joint ovate-lanceolate, slightly compressed, beaked, a 
third longer than the lower cylindrical one.—Drifting sands along the coast, near 
Brazos Santiago. A species common in Florida and the West Indies. 
18. RAPHANUS L. (RapDIsH.) 
Coarse introduced annuals or biennials, with elongated several-seeded 
beaked pods, which are either continuous or constricted between tlie 
seeds. 
1. R. Raphanistrum L. is known as ‘wild radish,” and is becoming a trouble- 
some weed. It may be known by its yellow petals, which are veined and become 
whitish or purplish, and its necklace-shaped pods, which are long-beaked, 1 to 
9-seeded, and break easily between the seeds.—Said to be abundantly naturalized 
along the lower Rio Grande. 
CAPPARIDEH. (CAPER FAMILY.) 
Ours are herbs, with alternate mostly compound leaves, racemose 
flowers, 4 sepals and petals, 6 or more (nearly equal) stamens, a single 
style and stigma, and a1 or 2-celled pod with kidney-sbaped seeds. 
* Fruit pod-like, 1-celled, several to many-seeded, 
1. Cleomella. Stamens 6: petals yellow, entire: pod very short, rhomboidal, 
long-stipitate. 
9. Cristatella. Stamens 6 to 14: petals white or yellow, fimbriate-toothed or 
laciniate ; pod linear, stipitate. 
8 Polanisia. Stamens 8 to 32: petals whitish or purple, notched at apex: pod 
elongated, shortly stipitate or not at all. 
** Fruit didymous, 2-celled, the cells separating as small 1-seeded nutlcts. 
4. Wislizenia. Stamens 6: flowers yellow: nutlets open at the scar. 
1. CLEOMELLA DC. 
Erect branching annuals, with 3-foliolate leaves, small yellow race- 
mose flowers, 6 stamens, and stipitate few-seeded rhomboidal pods with 
more or less distended or even conical valves. - 
1. C. angustifolia Torr. Glabrous, 3 to 6 dm. high: leaflets and simple bracts 
linear to linear-lanceolate, acute: valves of the rhomboidal pod bluntly conical: 
stipe shorter than the pedicel.—In gravelly soil and on high prairies, reported from 
near Houston to extreme western Texas. 
2. CRISTATELLA Nutt. 
Minutely viscid-glandular annuals, with 3-foliolate leaves and linear 
leaflets, fimbriate-toothed white or yellow petals, 6 to 14 stamens, and 
linear stipitate pods. 
1. C. Jamesii Torr. & Gray. Strict, somewhat branched, 3 dm. or more high: 
leaflets longer than the petiole: sepals obtuse: petals pale yellow, the blade of the 
lower ones palmately fimbriate-cleft.—Gravelly soil, between the Brazos and Pecos 
Rivers: said to be common on the “Staked Plains.” 
9. C. erosa Nutt. Rather slender and branching: sepals acute: petals white, the 
blade of the lower ones laciniately parted: flowers larger and pods longer than in 
the last.—At Lamar, on Copano Bay, and northeastward through Texas to Arkansas.
