105 
of many Cruciferous seeds. Embryo yellowish, thinly surrounded by albumen. Cotyledons elliptical, plane- 
convex, half as long as the cylindrical radicle. 
In flower throughout the greater part of the year. 
Zygropliyllum iodocarpum, F. M. in linncea , xxv. 372. 
Annual , diffuse, glabrous; stipules interpetiolar, almost deltoid; leaflets flesh}", geminate, oblong-cuneate, 
as long as or longer or shorter than the winged petiole, notched at the apex; terminal appendage of the petiole 
semilanceolate; pedicels generally geminate, slightly papillose, about as long as the flowers; sepals 5, persist¬ 
ent, ovate-lanceolate, more than half as long as the small oblong-spathulate yellow spotless petals; stamens 
10, about as long as the calyx; scales linear-cuneate, less than half as long as the filaments, entire; anthers 
yellow; liypogynons disk repand-undulated; ovary smooth, with two ovules in each cell; style very short; 
stigma lobed; capsule small , suhglobose-pentagonous , drooping, wingless, with loculicidal dehiscence; seeds 
compressed, solitary in each cell, nearly as long as its cavity; • raphe adnate; cotyledons broad-ovate. 
On dry subsaline desert-plains and on low barren ridges towards the Murray River below its junction 
with the Murrumbidgee; extending along the Darling into New South Wales; found also in the neighbor¬ 
hood of Lake Torrens and of the Elinders Ranges. 
Root almost cylindrical, tortuous, simple. Stems generally several, branched, from a few inches to 
fully 1 foot long. Branches almost semicylindrical. Stipules nearly 1 fine long, formed by the concrescence 
of those two opposite to each other, membranous and often somewhat fringed at the margin. Petioles 
conspicuously dilated by the partially reflexed herbaceous margin, terminated by an acuminate appendage, 
which measures |-1 line in length. Leaflets 3-6 fines rarely I inch long, 1-3 rarely 5 fines broad, some¬ 
times rounded blunt and without notch at the apex, occasionally reflexed at the margin. Pedicels 1-3 fines 
long, tliin-filifoim. Flowers cernuous. Sepals 1-1J fine long, by elongation narrow-lanceolate in age and 
then reflexed. Petals only about lh fine long, tapering into a conspicuous unguis. Filaments capillary, 
dilated below the middle by concrescence with the appendicular scale. Anthers ellipsoid or ovate, dorsifixed, 
about l fine long. Style capillary, not longer than fr.om J—| fine, with five disconnected minute stigmas. 
Capsule 2-3 lines long, exceeding often its height a little in breadth; when fresh somewhat carnulent and 
then only with slightly protruding angles; when dry angular with five acute sutural ridges, and then promi¬ 
nently net-veined, green or often assuming with many of the branchlets and leaves a violet hue. Endocarp 
nerve- and veinless, yellowish, polished at the inner side, separating easily from the sarcocarp and splitting 
into two regular valves. Funicles very short, generally originating not much above the middle of the cells. 
Seeds more compressed than in most other species, oblique-ovate, smooth, brown, shining', tapering towards 
the apex, about 1| fine long, emitting, immersed into water, from the testa a copious tough gelatine. Hilum 
lateral above the middle. Raphe narrow. Chalaza small, basilar. Albumen forming a very thin layer. Embryo 
hardly shorter than the albumen, yellowish. Radicle filiform, half as long as the outward slightly convex 
cotyledons. 
At Champion Bay and the Murchison River a plant without fruit was gathered by Mr. Aug. Oldfield, 
very similar to the species above described, of which it may be only a variety, differing in having externally 
a small basal lobe protruding from most of the leaflets and also one or the other terminal teeth, and in 
producing solitary pedicels about J inch long’ or even longer. 
In flower during the spring'.
