3. S. americana (Pers.) Fernald. Stems procumbent, the branches 2 or 3

10. SALSOLA L. SALTWORT 



Flowers perfect, with 2 bractlets. Calyx 5-parted, its divisions at length 

 horizontally winged on the back, the wings forming a broad scarious border. 

 Stamens mostly 5. Styles 2. Seed horizontal, without albumen. Herbs or 

 slightly shrubby branching plants with fleshy and rather terete or awl-shaped 

 leaves and sessile axillary flowers. (Diminutive of salsus, salty, alluding to the
