14. Gratia. Fruit-envelope strongly obcompressed, orbicular, longitudinally 

 wing-margined, smootli, colored. 



Tribe III. CoRisPERMEiE. Flowers perfect, not dimorphous, bractless. 

 Calyx 1-3-sepaled, hyaline, marcescent. Seed compressed, vertical, 

 •with closely adherent pericarp : albumen copious. Stems not jointed

15. CoRispERMUM. Fruit elliptic, not muricate, acutely margined : flowers 

 solitary, axillary. 



Tribe IV. SALicoRKiEiE. Flowers mostly perfect, not dimorphous, bract- 

 less, arranged by threes in close spikes. Stamens 1-2. Fleshy saline 

 plants, with jointed stems and scalelike leaves. 



16. Salicornia. Flower-clusters decussately opposite, sunk in the rachis 

 of the spike ; calyx saccate, fleshy, coherent to the rachis, becoming spongy : 

 albumen very small : branches opposite. 



17. Spirostachts. Flower-clusters spirally arranged ; calyx 4-5-cleft, the 

 sepals carinate : albumen rather copious : branches alternate. 



1. SALSOLA, Linn. 



Flowers perfect, 2-bracted. Calyx 5- (rarely 4-) sepaled, at length hori- 

 zontally 5-wingecl, enclosing the fruit. Stamens 5-3. Ovary depressed- 

 globose: style slender, with 2 linear stigmas, persistent. Fruit a 

 membranous utricle, loosely enveloping the horizontal subglobose 

 seed. Testa membranous : albumen none. — Saline plants with fleshy 

 sessile subcylindrical leaves and axillary sessile solitary flowers. 



1. S. Kali, Linn. Annual, herbaceous, erect or decumbent, ^2 

 feet high, diffusely branched, smooth or often roughly hispid ; leaves 

 alternate, ^1 inch long, semi-terete, amplexicaul, spinosely tipped, the 

 floral leaves ovate-lanceolate to ovate, with a broad base, strongly 

 nerved and spinose, and with the scarious margin often hispid-ciliate ; 

 bracts similar, somewhat smaller and unequal ; fruiting calyx turbinate, 

 truncate, the scarious sepals imbricated and connivent above into a 

 short beak ; wings pinkish, veined, orbicular, 3-4 lines broad. — Sea- 

 shore from New England to Georgia. The smoother form, with the 

 bracts and floral leaves naked, is the S. Caroliniana of Walter. The 

 integument of the seed is plainly double.
