40 Australian 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, ending 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 length 
interruptedly extended; bracteoles roundish-cordate; calyces 
somewhat silky, nearly sessile; pods slightly hairy. 
In dry pastures on the Thompson and Latrobe Rivers, and 
in South Australia, on the Torrens and Gawler Rivers, on 
the Barossa Ranges, 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 or 
pink corolla, and in the pod, which is neither black nor smooth. 
21. Psoralea adscendens. 
Smooth or sparingly pilose; stems herbaceous, diffuse 
adscending, 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 well 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 River, Gibbo 
River, Mitta Mitta, Ovens River, 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. 
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.
