3. SU^DA, Forsk. 



Flowers perfect, or rarely polygamous, minutely bracteolate. Calyx 

 5-parted or -cleft ; the lobes fleshy, uuappeudagecl or more or less 

 strongly cariuate or ci-ested, or becomiug somewhat winged, enclosing 

 the fruit. Stamens 5. Styles 2, rarely 3-4, short and rather stout. 

 Pericarp membranous, free. Seed compressed, vertical and with the 

 radicle inferior, or horizontal ; the testa smooth, black and crustace- 

 ous. — Herbs or shrubs with alternate subterete fleshy leaves, and 

 axillary clustered or solitary flowers. (^Chenopodina, Moq., Scho- 

 beria^ C. A. Meyer, &c.) 



* Calyx-lobes not appendaged : leaves narrow at base, 

 t Herbaceous annuals. 

 1. S. LINEARIS, Torr. MS. in herb. Smooth, nearly prostrate or 

 ascending, rather stout, the stems 1-2 feet long, with few ascending 

 branches ; leaves subterete, \-'i inches long, acute, the floral leaves 

 short, ovate to lanceolate ; calyx-lobes thick and strongly carinate or 

 gibbous in fruit ; stigmas 2, rarely 4 ; seed horizontal, § of a line 

 broad, very obscurely reticulately marked under a lens. — Seashore 

 lagoons, Carolina to Florida. A larger and stouter plant than aS*. 

 maritima of Europe, the seed larger and less strongly marked. The 

 true maritima is said by Hooker f. (in Fl. Arc.) to be common on the 

 arctic coast, and to have been collected by Richardson. There are no 

 arctic specimens in our herbariums. Moquin's species of this name is 

 variously confused.

 Var. RAMOSA. Erect and much branched, 1-2 feet high, the branches 

 subsimple, slender, and ascending ; floral leaves narrower, oblong to 

 linear-lanceolate ; seed smaller, ^ line broad. — On the seacoast from 

 the mouth of the St. Lawrence to Southern New England and New 

 York; Galveston (Lindheimer). Perhaps distinct, but the present 

 material is insufiicient for determination.
