2. SUZBDA Forsk. (Sta Brite.) 
Herbs or shrubs, with subterete leaves, axillary clustered or solitary 
sessile flowers, calyx-lobes unappendaged or more or less strongly 
keeled or crested or at length somewhat winged, 5 stamens, 2 or 3

*Calyx-lobes not appendaged: leaves narrow at base. 
+ Herbaceous annuals 
1. S. linearis Torr., var. ramosa Watson. Erect, much branched, 3 to 9 dm. high: 
branches nearly simple, slender, ascending: floral leaves oblong to linear-lanceolate: 
calyx-lobes thick and strongly keeled or gibbous in fruit: stigmas 3 (rarely 4): seed 
horizontal, 1 mm, broad.—From the New England coast to Galveston. 
2. S. diffusa Watson. Erect, 3 to 4 dm. high, diffusely branching, with usually 
slender flexuous branches: leaves 1.5 to 2.5 em, long, acute or acuminate; floral ones 
similar but shorter, usually rather distant on the branchlets: clusters 2 to 4-tlowered : 
calyx cleft to below the middle, fleshy but not keeled: seed mostly vertical, perfectly 
smooth, 1 mm. broad.—Common on the alkaline plains from Nevada and the Upper 
Missouri to northern Mexico and western Texas on the Rio Grande. 
++ Perennials with woody base. 
3. S. Moquini (Torr.). Erect, 6 to 9d. high, with herbaceous leafy branches, 
smooth or tomentose: leaves 1.5 to 2.5 em, long, inostly acute, the floral enes similar: 
clusters several-tlowered: calyx rather large, deeply cleft. seed vertical, finely tuber- 
culate, 15mm. broad, (Chenopodium Moquini Torr. 8. Torreyana Watson. )—From the 
Platte and Nevada to southern California and southern Coahuila. Doubtless to be 
found in western Texas. 
4. S. suffrutescens Watson. Shrubby or somewhat so, 6 to 9 din. high, with 
slender diffuse or divaricate leafy branches which are more or less tomentose: leaves 
numerous, mostly small, 1 to 1.5 em. long, linear to narrowly oblong, obtuse or acute: 
flowers solitary or clustered, small, with short lobes: seeds less than 1 mm. broad, 
very obscurely tuberculate.—Saline plains, from the Pecos Flats to the sandhills and 
ravines of Presidio del Norte. 
** One or moreof the ealyr-lobes more or less crested or transversely winged: herbaceous 
annuals, with leaves broadest at base. 
5, S, depressa Watson. Low and mostly decumbent, branching from the base, 
smooth: leaves .5 to 2.5 cm. long; the floral ones oblong- to ovate-lanceolate or ovate, 
rather crowded upon the branchlets: calyx cleft to the middle, with acute lobes: 
seed Lim. broad, lightly reticulate.—Saline soil of Pecos Flats, and extending far 
northward. Var. ERECTA Watson is erect, 3 to 6 dm. high, with short and rather 
strict branches, very narrow leaves, and narrower bracts.—Probably to be found in 
northwestern Texas, 
3. CYCLOLOMA Mogq. (WINGED PiGwEED.) 
Coarse and much-branched annual herb, with alternate petioled 
leaves, very small scattered sessile perfect or pistillate flowers in open 
panicles, concave strongly keeled calyx-lobes inclosing the depressed 
fruit, 5 stamens, 3 (rarely 2) styles, and flat seeds.

1. C. atriplicifolia (Spreng.). Ditfuse, 1.5 to 3.5 dm. high, more or less arachnoid- 
pubescent or glabrate, light green or often purple: leaves lanceolate, 2.5 to 5 em, 
long, coarsely sinuate-toothed. (Salsola atriplicifolia Spreng. C. platyphyllum
