 Varieties with leaves 2-lobed instead of 2-foliolate occur in Z. iodoca rpum, Z. prixmatotjieciim, 

 Z. Bilhirdicri, and Z. fntticulnxiiiii. ; with lobed or crenate leaflets in Z. fjluiicesccns and Z. 

 lodocarpmn ; and forms or states witli minute flowers in several of the species. 



1. Z. apiculatum (capsule apieulated), F. i\ M. in Lirmaa xxv. 878, and PI. 

 Vict. i. 101. A diffuse, glabrous undershrub. Leaflets 2, obliquely obovate or 

 rarely oblong, -Jf to lin. long, on a short common petiole. Flowers usually 5- 

 merous. Filaments with rather broad wings, adnate to above the middle and 

 toothed at the top. Capsule about 4 lines long, opening loculicidally, broader and 

 truncate at the top, the ancles very obtuse, and produced at the upper outer 

 corner into a short obtuse appendage. Seeds usually solitary in each cell. —

 Mosc. 1858, i. 487. 



Hab.: Darling Downs ; Mackenzie and Dawson Bivers,i^. v. M. (a very small-flowered variety). 



2. Z. glaucescens (glaucous), F. v. M. PL Vict. i. 228. Herbaceous, diffuse 

 or erect and glabrous. Leaves of 2 broad leaflets as in Z. apiculatum, the petiole 

 occasionally winged at the base. Flowers usually 4-merous. Filaments with 

 toothed wings as in Z. apiculatum. Capsule usually above fin. long, opening 

 loculicidally, the angles equally rounded at the. top and the base. Seeds 2 or 3 

 or sometimes 4 or 5 in each cell. — Z. qlauciim, F. v. M. in Trans. Vict. Inst. 

 i. 29; and PL Vict. i. 102 ; not of Sender.' 



Hab.: Eange about Toowoomba. 



Var. lobulatum, Benth. A small annual. Leaflets irregularly 2 or 3-lobed or deeply crenate. 

 Flowers and fruit precisely as in the ordinary form. — Z. crenatum, F. v. M. in Linnsea, xxv. 374, 

 and PI. Vict. i. 103, t. 6. On the Lachlan and Murray Elvers, and in the interior of S. Australia 

 and Queensland, F. v. M. 



3. Z. iodocarpum (violet fruited), F. v. M. in Linnma, xxv. 372, and PI. 

 Vict. i. lO.j. A small, much-branched, diffuse annual. Leaflets oblong- cuneate 

 or almost linear, very obtuse, rarely ^iu. long, the petiole often 2-winged, espe- 

 cially towards the top. Flowers very small, usually 5-merous, the petals not 

 2 lines long. Filaments dilated at the base into short, narrow, entire wings, 

 entirely adnate or very shortly free. Capsule 2 or rarely 3 lines long, loculicidal, 

 the angles equally rounded at the top and the base. Seeds solitary in each cell. 



Hab.: Queensland, F. v. 31. I 



4. Z. prismatothecum (prism-shaped fruit), F. v. M. in Linnaa, xxv. 375. 

 A much-branched, small annual. Leaves rather thick, the leaflets, in the few 

 specimens seen, short and confluent with the more or less dilated petiole, so as to 

 form a single two-lobed leaf. Flowers, which I have not seen, small and 

 4-merous according to F. v. Mueller, the filaments dilated at the base and 

 toothed or entire. Capsules nearly sessile, oblong, 4-angular, about 4 lines long, 

 of equal breadth at the base and the top, where the angles terminate in small 

 erect leafy appendages. Seeds solitary in each cell. 



Hab.: Border-land adjoining S. Australia, F. v. M. 



The very few specimens seen have all the foliage oi the 2-lobed varieties of Z. iodocarpum, Z. 

 Billardieri, and Z. fruticulosum, but as in those species there is probably also a variety with 

 normally 2-foliolate leaves. — Benth,
