PLANTS INDIGENOUS TO 
[Zygophyllece. 
broad, less fleshy than in most other Australian species, flat, rather vividly green, in a fresh state shinin- 
blunt; their exterior half the broadest. Terminal appendage of the leafstalk persistent, about 1 line long 
Pedicels solitary or more frequently twin, affixed at the axis of the anterior interpetiolar stipules. Plovers 
without scent. Sepals about 2 lines long, green, reflexed in age, appressed during florescence. Petals 
gradually contracted into a pale claw. Stamens as long as or longer than the calyx, outside adnate to the 
very tender below hyalinous in front yellow scales, which are 1-2 lines long, sometimes denticulated in 
front and free from the filaments at the very summit, whilst the latter becomes confluent with the scale below 
and appears not prominent towards the base. Free part of filaments intensely yellow. Anthers about § line 
long, attached to the filament below their middle dorsal part, ovate or oblong-ovate, with emarginate base. 
Style simple by the concrescence of five, hardly 1 fine long, subulate, green, long persistent. Stigmas 
exceedingly small, united. Hypogynous ring very nairow, glabrous outside, with eight folds, which correspond 
to the exterior insertion of the filaments. Capsule 4-5 occasionally only 3 lines long, measuring across the 
vertex nearly i inch, rounded blunt at the base. Sarcoearp thin, net-veined. Endocarp polished, nerveless, 
pale-yellow, m age slowly seceding and breaking into two incurved valves. Column angular-filiform, 
persistent. Seeds pendent, oblique-obovate, slightly compressed, rather shining, indistinctly wrinkled, 1J-2 
lines long, obscurely grey-brown, at the apex attenuated. Funicles very short. Raphe livid, prominent 
stretching from below the apex to the base of the seed. Chalaza inconspicuous. Testa when macerated 
exuding a copious tenacious mucilage. Albumen not quite equal in thickness to the embiyo, which is 
yellowish-green. Radicle cylindrical, half as long as the ovate plane-convex cotyledons. 
Zyg-ophyllum glaucum, F. M. in Transact, of the Viet. Inst. i. ay. 
Herbaceous, prostrate, difiiise, ascending or erect, glabrous; branches compressed-terete; stipules 
interpetiolar, deltoid; leaflets geminate, fleshy, oblique- or cuneate-obovate, blunt, perfectly entire, at least 
three times as long as the margined petiole; terminal appendage of the leafstalk semilanceolate; pedicels 
solitary, as long as or longer than the leafstalk, shorter than the flowers; sepals 4, broad-ovate or lanceolate 
persistent, several times shorter than the obcordate-ovate or obovate yellow petals; stamens 8, twice as Ion- 
as the sepals, half as long as the petals; scale cuneate, half as long as the filament, acutely bidentate at the 
apex teethless at the sides; hypogynous disk very narrow, repand, slightly velvety at the margin; style 
s iort; stigma minute, four-lobed; ovary glabrous, with 7-9 ovules along each cell; capsule drooping,almost 
obovate-tetragonous, wingless, rounded blunt at the base and apex, with locuhcidal dehiscence; seeds 3-5 in 
In the subsaline desert-plains along the Murray River, the Wimmera and the Avoca; in South 
Australia ori the foot of the Barossa Ranges, on St. Vincent’s and Spencer’s Gulf, and on Venus Bay; in 
JNew South Wales on the Darling River.
