AUSTRALIAN PLANTS. 45 



the leaflets ; bracteoles lanceolate-ovate, acuminate ; pods black, 

 wrinkled-scabrous. 



Hab. On the grassy moist banks of the Snowy Eiver, Gibbo Eiver, 

 Mitta Mitta, Ovens Eiver, and along the torrents of the Australian Alps. 



This fine plant approaches nearer to P. Australasica than to F, ienax; 

 the colour of the flowers is purple, like that of the former, not deep 

 blue as in the latter, from which it differs besides in the greater size of 

 all parts and the above notes. It may be considered a subalpiue plant, 

 whilst P. tenax hardly advances anywhere into the mountains. 



68. Leptocyamus sericeus, F, Muell, ; all over grey-silky; stems 

 procumbent; leaflets lanceolate -linear, acuminate, above at length a 

 little glabrescent ; pedicels axillary, subsolitary ; pods silky ; seeds 

 shining-black, even. 



Hab. On sand-ridges along the Murray Eiver, towards the junction 

 of the Murrumbidgee, 



To the same genus belongs Zichya Latroheana of Meisner (in Leh- 

 mann Plant, Preiss, i. p. 94). 



69. Cassia r^ToZw/^, F. Muell.; shrubby; leaves with a channelled 

 rachis, and with six to ten pairs of leaflets, which are linear-lanceolate, 

 pointed, smooth above, hairy beneath as well as along the revolute 

 margins, a subulate gland between each pair ; stipules linear-subulate ; 

 bracteoles cymbiform-ovate ; peduncles axillary, about as long as the 

 leaves, with from two to four umbellate flowers, together with the 

 branches ; pedicels and rachis pubescent ; sepals ovate, glabrous, ciliate, 

 the outer ones broader ; one petal much shorter than the rest, nearly 

 round ; legume stalked, smooth, slightly arched. 



Hab. On gravelly, sometimes overflown, places along the Avon in 

 Gipps' Land. 



The systematic position of this Cassia will be between G» Australis 

 and C Schultesii. 



70. Acacia tenuifolia^ F. Muell. ; procumbent or rarely erect, twigs 

 soon terete, hispidulous ; leaves scattered, opposite or sometimes fas- 

 ciculate, spreading, often retroflexed, linear-subulate, rigid, pungent, 

 nearly tetragonal from the prominent nerve, hardly tapering into the 

 base, glandless, scabrous ; stipules setaceous, persistent ; peduncles 

 solitary or twin, smooth, about as long as the leaves ; heads globose, 

 naany-flowered ; sepals ciliolate, nearly three times shorter than the 



♦ Is A, Brownii, Bcnth.
