NortH AND SoutH IstaAnps: Not uncommon in salt marshes from the 
North Cape to Foveaux Strait. December—March. 
The Australian and New Zealand plant is sometimes separated from the 
northern form under the name of S. australis, Moq., on account of its more 
suffrutescent habit, but it is very variable in this respect. 
6. SALSOLA, Linn. 
Herbs or shrubs; branches not jointed. Leaves alternate, 
sessile, narrow-linear or terete, often pungent. Flowers small, 
solitary or fascicled, axillary, hermaphrodite, 2-bracteolate. 
Perianth 4—5-partite ; segments concave, thickened down the back, 
enlarged in fruit and furnished with a horizontal wing or pro- 
tuberance, completely enclosing the utricle. Stamens 5, rarely 
fewer. Styles 2-3, subulate, erect or recurved. Utricle ovoid or 
orbicular; pericarp fleshy or membranous, not adherent to the 
seed. Seed usually horizontal, orbicular; testa membranous ; 
albumen wanting; embryo spirally coiled. 
Species estimated at about 40, widely spread in saline localities, but mainly 
in temperate regions. 
1. S. Kali, Linn. Sp. Plant. 222.—A rigid procumbent or 
diffusely branched herb 6-18in. high; stem stout, grooved and 
angled, scabrid-pubescent or almost glabrous; branches spreading, 
often striped. Leaves spreading and recurved, variable in size, 
4-lin. long or more, ovate-subulate with a rigid pungent point, 
sheathing at the base, thick and fleshy, semi-terete ; the upper- 
most shorter and broader, almost triangular. Flowers solitary and 
sessile in the axils of the leaves, sometimes appearing clustered 
from the reduction of axillary flowering-branches, each flower with 
2 opposite bracteoles; floral leaves and bracteoles all pungent. 
Fruiting-perianth about +in. diam., shorter than the bracteoles, 
5-partite ; segments rigid and cartilaginous at the base, furnished 
above with 5 broad spreading scarious wings.—Benth. Fl. Austra.

Norra anp Sours Is~tanps: Not uncommon on sandy shores from the 
North Cape southwards, but probably introduced. December—March. 
A widely dispersed plant in most temperate and tropical regions, but of very 
doubtful nativity in New Zealand. It is a true native of Australia, however. 
Orpver LXV. POLYGONACEA. 
Herbs or shrubs or woody climbers. Leaves alternate or rarely 
opposite, simple, entire or serrulate. Stipules thin, scarious or 
membranous, forming a sheath round the stem. Flowers small,

jointed on the pedicel, clustered in the axils of the leaves or in
