CL C'HEXOPODIACEiE. 
[Arthrocnemum. 
Articles often Jin. long in the principal branches, 1 to 2 lines in the 
smaller ones, dilated at the top but without prominent lobes. Spikes 
terminal, thick, ovoid or oblong, rarely above Jin. long but varying much 
in diameter, consisting of 2 to 6 articles deeply excavated and cupshaped 
at the top with more or less prominent lobes or scales. Flowers in 
threes, all monandrous and hermaphrodite, at first shorter than the scale but at 
length somewhat exserted, all cohering with each other at the base and immersed 
in and adnate to the article above them, with short free thin lobes, opening in 
fruit so that after flowering each ovary appears to be in a separate excavation of 
the rliachis, with a membranous fringed border. In fruit the lateral ovaries are 
often abortive, and the central pericarp grows out into a prominent beak (the 
thickened base of the styles), projecting horizontally considerably beyond the 
subtending scale. — Hook. f. FI. Tasin. i. 316; Arthrocnemum haloc nemo ules, Nees

Hab.: Southern coast. 
13. SALICORNIA, Linn. 
(From sal, salt, and cornu, a horn.) 
Perianth obpyramidal, 3 to 4-toothed, fruiting spongy. Stamens 1 to 2 ; 
utricle included in the spongy perianth, membranous; stigmas subulate. Seeds 
erect, compreesed ; testa hispid with hooked hairs. Albumen none. Embryo 
conduplicate, radicle inferior, parallel to the folds of the cotyledons. Herbs or 
shrubs with the habit of Arthrocnemum, but with the flowers sunk in cavities 
of the joints. 
Species few, of tropical and temperate parts. 
Flowers in threes, all or the central one hermaphrodite. Spikes continuous, 
the margins of the articles broad-obtuse and not prominent 1. S. leiustachya. 
Flowers in threes, unisexual. Articles of the spikes with prominent 2-lobed 
margins 2. S. tenuis. 
Flowers in fives or sevens, mostly hermaphrodite. Articles of the spikes 
with slightly prominent annular margins 3. S. australis. 
1. S. leiostachya (spikes smooth), Benth. FI. Austr. v. 203. A spreading 
much-branched shrub of 2 or 3ft., the articles of the branches cylindrical, J to 
^in. long, slightly thickened but not lobed at the top. Spikes numerous, nearly 
sessile and opposite at the nodes or terminal, cylindrical, compact, J to nearly 
liu. long; articles numerous, at first rather distinct with their obtuse margins 
slightly prominent, but at length very closely packed into an apparently continuous 
spike of 2 lines diameter, without prominent scales, the separation of the articles 
only marked by slightly depressed transverse lines. Flowers in threes, wholly 
immersed and closely packed side by side, all hermaphrodite and monandrous, 
but often only the central one perfecting its seed. Perianths thickened upwards, 
with a narrow triangular obliquely truncate top. Seed apparently compressed 
and vertical but not seen very perfect. 
Hab.: Northern localities. 
2. S. tenuis (slender), Benth. FI. Austr. v. 204. A divaricately-branched 
or diffuse shrub, more slender than the other Australian species. Articles of the 
branches J to Jin. long, the upper end dilated into a membranous sometimes 
scarious margin. Flowers apparently dioecious, both sexes in threes. Male 
spikes short, but only commencing to flower in the specimens seen, probably at 
length elongated, the articles larger and broader than in the females, with 
scarious margins. Perianths all three distinct and slender, with 1 stamen in 
each, and no trace of pistil. Female spikes slender, 1 to 2in. long, the articles 
4 to above 1 line long. Perianths free, at first almost in a line, at length in a
