Salsola.] CHENOPODIACEvE. 413 



Subdivision IV. MONOCHLAMYDEM. 



" Flowers incomplete. Perianth single ; in other words, the 

 calyx and corolla forming but one floral covering, or altogether 

 wanting." — Br. Fl. 



Order LXIII. CHENOPODIACEiE. 



" Sometimes monoecious or polygamous. Perianth free, gene- 

 rally deeply cleft and without bracteas at its base. Stamens 

 mostly 5 (in Salsola 2 or 1). Stamens from the base of the peri- 

 anth and opposite to the segments : anthers 2-celled. Ovary 1, 

 1-celled, with a single ovule. Style divided, rarely simple. Fruit 

 indehiscent (usually a utricle, sometimes a berry). Seed 1, at the 

 base of the cell. Embryo spiral and without albumen, or curved 

 round a farinaceous albumen. Herbs, rarely shrubs, tvithout sti- 

 pules. Flowers small, inelegant." — Br. Fl. 



Tribe I. Salsole.^. 



" Seed with a simple integument. Embryo in a conical spiral. 

 Stems continuous or jointed." — Sode^. — Br. Fl. 



I. Salsola,* Linn. Saltwort. 



"Flowers perfect, bracteated at the base. Perianth simple, 

 inferior, 5 -partite, persistent, enveloping the utricle with its base 

 and crowning it with its limb, which has a broad scariose dorsal 

 wing. Stamens 5. Styles 'i. ^'ee^is horizontal ; integument sim- 

 ple, membranaceous" — Br. Fl. 



Very closely related to Chenopodium, to which one of our two former British 

 species is now referred ; the present differs from that genus chiefly in the shape 

 of the fruit, the dilated perianth and spiral cotyledon. 



1. S. Kali, L. Prickly Saltwort. " Stems herbaceous pros- 

 trate, leaves subulate spinous scabrous, flowers axillary solitary, 

 segments of the enlarged perianth cartilaginous as long as their 

 spreading roundish wings." — Br. Fl. p. 352. E. B. t. 634.
