A very variable species, of which specimens occur occasionally with here and there an ad- 

 ditional pair of leaflets, showing an approach towards C. ariemisioides, and some of the 

 western ones with the gland rathe^ more prominent are at first sight like reduced forms of 

 C, Chaielainiana, The two following varieties which have heen distinguished as species, 

 are very inconstant j they both occur mixed with the common form. 



Var. plafj/jjoda. Petioles vertically compressed, the lowxr ones often without leaflets.— 

 C, plait/ poda, E. Br. in App. Stmt Exped. 15. 



Var. zygophf/lla. Leaflets 1 or 2 pairs, linear, flat, often 1 to 2 lines broad.— (7. zt/gopJfylla, 

 Benth. in Mitch. Trop. Austr. 288. 



18. C. artemisioides. Gaud, in DC. Frod. ii. 495. An erect bushy 



slirub, hoary or ^vhite with a minute silky toitientum. Leaflets 3 to 6 pairs, 

 linear-terete and more or less channelled above, slender but rigid, usually 4 

 to 1 in. long, but sometimes longer or shorter ; glands small and flat between 

 those of the lower 1 or 2 pairs. Flowers in a short dense raceme on pedun- 

 cles much shorter than the leaves. Bracts small, ovate. Sepals obtuse, 2 to 

 2i lines long. Petals about twice as long. Anthers 2 or 3 longer than the 

 others on longer filaments. Po4 straight, 2 to 3 in. long, about 4 lines broad.

Nearly allied to C. ermopMla ^nd C. Sturtii, this diiFera from the former chiefly in the 

 more numerous leaflets, from the latter in their shape and in the narrower pod. If tue ttire 

 were united, it is the name of C. artemisioides that Jiaa the priority. 



19. C. Sturtii, K Br. in Jpp. Sturt Exped, U. A bushy shrub, gla- 

 brous or more frequently glaucous hoary or white with a close tomentum. 

 Leaflets usually 3 to 5 pairs, linear, lanceolate, cuneate, elliptical or a haos 

 obovate, ^ to 1 in. long, thick, flat or concave, sometimes all small and almost 

 ovate, the lower leaves rarely with only 2 pairs ; glnnds small between tne 

 leaflets of the lowest 1 or 2 pairs. Stipules small and deciduous as m all tne 

 allied species. Flowers in short axillary dense racemes as in C, eremopni ^, 

 but usually more numerous on a longer peduncle. Sepals obtuse, 2 to 3 im^ 

 long, frequently tomentose. Petals twice as long. Pod when perfect lu > 

 ^ in. broad, straight or slightly curved and very obtuse.
