Zygophyllece.\ 
THE COLONY OE VICTORIA. 
103 
bright-yellow, nearly 4 lines long', finely striped with, dark-yellow veins, generally somewhat tinged with red 
towards the base, yet not decidedly spotted, tapering gradually into the pale unguis. Filaments inserted 
outside the hypogynous disk, all of about equal length, externally adnate to the tender scale, which is about 
2 lines long, smooth, yellow towards the top, hyalinous below, and occasionally slightly denticulated at the 
truncate apex, where it is wholly adnate to the filament and projects on both corners. Free part of filaments 
yellow, glabrous, capillary-setaceous. Anthers versatile, ovate, nearly 1 line long, affixed at the back a little 
below the middle, slightly bilobed at the base. Pollen-grains ellipsoid, smooth, longitudinally slit. Style 
subulate, finely four-streaked, formed by the coalescence of four, about I line long, persistent, greenish. 
Lobes of stigma or disjointed stigmas minute, spreading', very short, often conglutinated. Ovaiy quadran¬ 
gular-ovate, blunt, with four shining-green prominent angles. Hypogynous disk at first green, plicate, 
repand-four-lobed, J line high, covered with a faint velvet at the margin, glabrous outside, each sinus 
opposite to an ovary-edge. Ovules oblique-pendent, occupying in two rows nearly the whole length of the 
cells. Capsule 6-9 lines long, generally about 5 lines broad, very blunt particularly at the apex, occasionally 
almost truncate, yet always rounded at the corners, when short with dimidiate subcordate cells, when long 
with dimidiate subovate divisions. Sarcocarp densely net-veined, when diy almost membranous, in age 
irregularly separating from the yellowish smooth polished nerveless nearly pergamentaceous endocarp. 
Funicles veiy short. Seeds 1^-1 f line long, slightly or hardly compressed, oblique ellipsoid or ovate, 
brownish. Raphe drawing from below the apex to the base of the seed, prominent. Chalaza inconspicuous. 
Testa when macerated mucilaginous. Endopleura brown, almost membranous. Layer of albumen, which 
surrounds the embryo, rather thin. Cotyledons plane-convex, ovate, twice as long as the cylindrical radicle. 
Zyg*ophyllum crenatum, F. M. in IAnneea, xxv. 374. 
Annual, glabrous, procumbent or ascendent, rarely erect; stipules deltoid, interpetiolar; leaflets gemi¬ 
nate, fleshy, oblique cuneate, crenate at the apex, longer than the winged petiole or some nearly as long ; 
terminal appendage of the petiole subulate-lanceolate; pedicels solitary, shorter than the flower ; sepals 4, 
ovate or ovate-lanceolate, persistent, at least half as long as the yellow obovate-cuneate spotless petals; 
stamens 8, nearly half as long as the corolla; scale cuneate, extending scarcely beyond the middle of the 
filament, jagged-fringed towards the bifid apex; anthers yellow; hypogynous disk divided into four short 
nearly semiorbicular lobes; style short; stigma minute, four-lobed; ovary glabrous, with 7-9 ovules along 
each cell; capsule drooping, subomte-tetmgonous, margined with exceedingly narrow wings, rounded at the 
base and at the apex, with loculicidal dehiscence; seeds 4-8 in each cell; raphe adnate. 
On the sandy or subsaline depressions along the Murray River downward from its junction with the 
Murrmnbidgee to the western boundaries of the Colony of Victoria. In South Australia towards Spencer’s 
Gulf, Lake Torrens and the Flinders Ranges. 
A carnulent herb, with stems from a few inches to fully 1 foot long. Branches semiterete. Petiole 
margined with broader or narrower leafy wings, which are dilated towards the rounded or truncate base. 
Stipules deltoid or sometimes semilanceolate, rarely longer than 1 line. Leaflets J-l inch long, i-5 lines 
broad, with a few blunt teeth at and near the apex. Pedicels cylindrical, 2-4 lines long', bent downward 
in age. Sepals about 2 lines long, or in age somewhat longer, and then reflexed, acute, greenish. Petals 
tapering into a claw, very blunt or slightly emarginate at the apex. Filament about 2 lines long, adnate to 
the very tender scale, setaceous at the apex. Anthers nearly ellipsoid, dorsifixed, yellow', about J line long. 
Pollen-grains ellipsoid, smooth, bursting lengthwise. Style shorter than 1 line. Capsules 7-9 lines long, 
about 5 lines broad, prominently quadrangular. Sarcocarp thin, reticulate-veined. Endocarp tardily and 
very incompletely secedent, yellowish, very shining. Seeds 1J—2 lines long, ovate, somewhat compressed, 
toward the apex attenuated, dull brown on account of the indurated mucilaginous testa concealing the 
dark-brown endopleura. Raphe, albumen and embryo not essentially different from those of the preceding 
species, which bears to it a close relationship.
