1O. SALICOBNIA, Tourn. GLASSWORT. SAMPHIRE. 



Calyx a fleshy rhomboidal sac with an anterior opening, adherent by a nar- 

 row line to the rhachis. Stamens 1 or 2, exserted in flower. Styles 2 or 3, 

 short. Low fleshy leafless saline plants, mostly herbaceous : spikes cylindrical. 



1. S. herbacea, L. Erect or at length spreading, green: spike very 

 thick and fleshy : scales obscure and very blunt, making a truncate barely 

 emarginate termination of the joints of stem or elongated spike. In salt 

 marshes from Colorado and Utah to the Saskatchewan and along the Atlantic 

 coast. 



11. SARCOBATUS, Nees. GREASEWOOD. 



Flowers monoecious or dioecious, without bracts. Stamens 2 to 5, irregu- 

 larly arranged under a stipitate peltate scale ; anthers fleshy. Perianth adhe- 

 rent at the contracted somewhat 2-lipped apex to the base of the stigmas, 

 laterally margined by a narrow erect slightly 2-lobed border, which at length 

 becomes a broad circular horizontal membranous veined wing. Style lateral, 

 terminated by two thick exserted unequal stigmas. A rigidly and divaricately 

 branched shrub : leaves linear. 



1. S. vermiculatUS, Torr. Erect and scraggy, 2 to 8 feet high, leafy; 

 branches with a smooth white bark : staminate spikes terminal, the persistent 

 scales spirally arranged, rhombic-ovate. Common in the Great Basin, and 

 to the Upper Missouri, head-waters of the Platte, and southward. The com- 

 monest of the several shrubs called " Greasewood." 



12. SU-EIDA, Forskal. SEA ELITE. 



Flowers minutely bracteolate. Lobes of the calyx unappendaged or more 

 or less strongly keeled or crested, or at length somewhat winged. Testa 

 shining, black, and crustaceous. Flowers axillary along the branches, clus- 

 tered or solitary, sessile. 



* Herbaceous annuals. 



1 . S. diffusa, Watson. Erect, diffusely branching : leaves subterete ; the 

 floral ones similar but shorter, usually rather distant on the branchlets : clusters 

 2 to 4-flowered : calyx cleft to below the middle, not carinate or appendaged. 

 Proc. Am. Acad. ix. 88. S. maritima of Bot. King Exped. From the Upper 

 Missouri to California, Mexico, and Texas. 



2. S. depressa, Watson. Low and mostly decumbent, branching from the 

 base : leaves linear, broadest at base; the floral ones oblong- to ovate-lanceolate or 

 ovate, rather crowded on the branchlets : calyx cleft to the middle, one or more 

 of the lobes strongly carinate or crested. Bot. King Exped. 294. From Colo- 

 rado to Nevada and the Saskatchewan. 



Var. erecta, Watson. Erect, with very narrow leaves and narrower 

 bracts. Proc. Am. Acad. ix. 90. S. maritima of Fl. Colorado. Same range 

 as the type, but extending into S. California. 



* * Woody-based perennials. 



3. S. Torreyana, Watson. Erect, with herbaceous leafy branches : 

 leaves linear, subterete, the floral ones similar : calyx rather large, deeply 

 cleft : seed finely tuberculate. Loc. cit. 68. S.fruticosa of Bot. King Exped. 

 From N. Colorado to Nevada, S. California, and Mexico.
