816 FLORA OF TASMANIA. [CItenopodiacea. 
which are very widely diffused, and often variable ; two are natives of Australia, one a common Indian plant, which 
is found on the tropical shores, and the other the Tasmanian species, which I have vainly attempted to distinguish 
from the European S. maritima, and which is, I believe, found in all quarters of the globe, under various names. — 
S. maritima is a small, bushy herb, 1-2 feet high, with a woody, erect, or prostrate stem, and herbaceous branches, 
covered with linear, subcylmdncal, sessde, glabrous or farinose leaves, about |-1 inch long. Flowers small, solitary 
or clustered in the axils of the leaves, green, hermaphrodite, bibracteate. Perianth urccolate, five-cleft. Stamens 
five. Styles two, united at the base. Utricuhs membranous. Seed very minutely punctate, horizontal or obliquely 
erect, with a rather acute margin ; embryo coiled spirally. (Name from Suad, an Arabic word for a plant yielding 
Soda.) 
1. Suseda maritima (Dumort. Flor. Belg. 22) ■ herbacea, basi suffruticosa, ramosissima, foliis sub- 
acutia supra planis glabris, floribus 2-3-glomeru! Efero inflato carinato, semine horizon- 
tali v. suberecto margine subacuto punctulato nitido orbiculari v. obliquo et rostellato. — FL K Zeal. i. 
214. Chenopodina maritima, Australasia?, et tortuosa, Moq. Tand. in DC. Prodr. xiii. 161. Chenopodium 
australe, Br. Prodr. 407. {Gunn, 391.) 
Hab. Abundant on mud and shingle beaches, close to high- water mark. — (Fl. Nov.) (v. v.) 
Distrib. Extratropical shores of Australia and New Zealand ; Europe, Asia, America, and Africa. 
When preparing the New Zealand Flora, I compared this plant very closely with the European, and believed 
it to be entirely the same, and I have now . . in examini d it with the same result. The utriculus, though gene- 
rally depressed, and containing a horizontal orbicular seed, is occasionally obliquely ascending or suberect, when 
the seed is also oblique and rostellate at the hilum.

Flores hermaphroditi, ebracteati. Perianthium carnosum, turbinatum, rhacheos excavationibus im- 
mersum. Stamina 1-2, fundo perianthii inserta. Ovarium, stylis 2, subulatis, basi connatis. Utricuhs 
perianthio inclusus. Semen erectum v. subhorizontale ; albumine carnoso ; embryone cyclico.— Herbse v. 
suffrutices aphr/lla, salsa; caule erecto v. prostrato ; ramis articulatis. 
Several species of this curious and widely-spread genus are natives of Australia, including the genera Artlroc- 
nemum and Hcdioenemnm, which are so extremely similar, and differ in such minute characters only, that it does not 
seem natural to separate them generically.— Leafless succulent herbs or smaU shrubs, growing in salt-marshes, and 
having woody or herbaceous, erect or prostrate stems, and jointed herbaceous branches ; joints generally cylindrical 
below, and dilated and truncate above. Flowers hermaphrodite, very inconspicuous, sunk in the substance of the 
joints, which are often short, and crowded towards the ends of the branches, forming a sort of cone. Perianth 
ebracteate, urccolate. Stamens 1-2. Ovary with two styles, which are connate at the base. Fruit a membranous 
utriculus, sunk in the bottom of the perianth, with one erect or vertically depressed seed. (Name from sal, salt, 
and coniu, a horn.) 
1. Salicornia Arbuscula (Br. Prodr. 411) ; caule suberecto subgracili lignoso ascendente ramosis- 
simo, ramis subligneis, ramulis articulatis herbaceis, articulis elongato-clavatis apice rafundibuliformibus, 
spicis brevibus lateralibus terminalibusque crassis obtusis.— Arthrocneinum Arbuscula, Moq. Tand. En. 
Chenop. 113, et in DC. Prodr. xiii. 152. 
Hab. Probably common, but I have it only from salt-marshes in the neighbourhood of Hobarton and 
Clarence Plains.— (Fl. Oct.) {v. v.) 
Distrib. Tropical and subtropical Australia. 
A small rigid shrub, 1-3 feet high, with woody, much branched stems, and short, opposite and alternate 
jovnted branches. Fleers monandrous, in the shorter terminal joints, which together form a small spike or stro- 
bilus about \ mch long.
