146 XL. LEGUMINOS^. [Uutoxia, 



linear, 1 to 3 lines long, rigid, concavCj obtuse or almost acute, without any 

 dorsal midrib, rarely broadly oblong or almost ovate or obovate. Flowers 

 small, on axillary pedicels of 1 to 2 lines, with a pair of leafy linear obtuse 

 bracteoles a little below the calvx. Calyx o-labrons, 11 to nearly 2 lines 

 long; lobes acute or acuminate, rather longer than the tube, the 2 upper 

 ones more or less united. Standard about 3 lines long or rather more; lower 

 petals shorter, the keel deeply coloured. Ovary stipitate, silky-villous; style 

 subulate, incurved. Pod ovoid or nearly globular, very turgid, varying from 

 1^ to nearly 3 lines long, and the stipes from ^ to I'line. Seeds black.—

The extreme forms of this plant are so ditFerent in aspect that it is difficult, at first sight, 

 to consider them all as varieties of one species. Most of those from the mountain districts 

 of Victoria are unarmed, with broadly cuueate-oblong leaves of 2 or 3 lines or even longer; 

 many from the Murray scrub and South Australia are stunted, spinesccnt, with very mime- 

 reus narrow leaves, from -J to 1 line long ; Druiumoud's W. Austi'aliau ones are heath-like, 

 unarmed, with tine sleuder leaves of 1 to 2 or even 3 lines ; others again, from near the 

 Great I5ight or from the scrub of S. Australia and Victoria, have short broad leaves or m 

 some instances two or three of the above forms are on the same specimen. The size of the 

 pod and the length of the stipes also vary much and not in any relation to the differences in 

 the foliage.

shortly stipitate, with 2 ovules on short funicles; style erect, rather tliicK, 

 hooked below the top, with a truncate or thick stit^inn. Tod nearly sessile, 

 ovate or rounded, turgid, 2-vaIved. Seeds reuiforni, strophiolate.— Heath- 

 hke shrubs. Leaves alternate or scattered, simple, narrow-linear or teret«, 

 chanuelled above. Stipules none. Flowers yellow or orange-red, few toge- 

 ther in axillary or terminal racemes or corymbs, rarely solitary. I5i'^^^^ 

 small, brown, very deciduous ; bracteoles small on the short pedicels. 



Tlic genus is entirely Australian. It differs from Aotus in the strophiolate seeds and 10 

 the leaves channelled above and not underneath, from Paltenaa in the bracteoles at a disUBC^ 

 from the calyx and usually deciduous, from Lairohea in the calyx style and pod, but is dos«^J 

 connected with the two latter genera through D. hrunioides.
