Aastrdlian Plants, 



20. Psoralea parva, 



^ Sparingly pilose; stems herbaceous, procumbent, almost 

 simple; leaves trifoliolate, on long petioles; leaflets narrow- 

 lanceolate or of the radical leaves elliptical, perfectly entire, 

 dotted, endmg in a sharp point, the intermediate one larger; 

 stipules streaked, ovate-lanceolate, with a subulate apex, 

 peduncles long; spike at first capitate, but generally at leno-th 

 interruptedly extended; bracteoles roundish-cordate; calyces 

 somewhat silky, nearly sessile; pods slightly hairy. 

 ^ In dry pastures on the Thompson and Latrobe Rivers, and 

 m South Australia, on the Torrens and Gawler Eivers, on 

 the Barossa Eanges, near Villunga, &c. 



It differs from Ps. tenax in always trifoliolate smaller and 

 less acute leaves, in sessile less deeply divided calyces, in the 

 form of the longer persistent bracteoles, in the whitish ox 

 pmk corolla, and in the pod, which is neither black nor smooth, 



21. Psoralea adscendens. 



Smooth or sparingly pilose; stems herbaceous, diffuse 

 adscendmg, at the base procumbent; leaves trifoliolate, on 

 long petioles; leaflets lanceolate, acuminate, entire, sharp 

 pointed, dotted, the intermediate one larger; stipules lanceo- 

 late-subulate; peduncles long, upwards as w^ell as the calyces 

 somewhat hairy; racemes dense, almost spicate, many-flowered, 

 of the length of the leaflets; bracteoles lanceolate -ovate, 

 acuminate; pods black, wrinkled-scabrous. 



On the grassy moist banks of the Snowy Eiver, Gibbo 

 Kiver, Mitta Mitta, Ovens Eiver, and along the torrents of 

 the Australian Alps. 



This fine plant approaches nearer to Ps. Australasica than 

 to Ps. tenax; 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 subalpine plant, whilst Ps- 

 tenax hardly advances any where into the mountains. 



22. Leptocyamus sericeus. 



. AH over grey — ^silky; stems procumbent; leaflets lanceolate- 

 linear, acuminate, above at length a little glabrescent; 

 pedicels axillary, subsolitary; pods silky; seeds shining- 

 black, even.
