Psoralea pustulata. 



Suffruticose, erect, covered with short appressed hair and 

 conspersed with glandular tubercles and minute warts ; 

 stems simple ; petioles almost as long as the leaflets ; 

 stipules large, hastate- or lanceolate-ovate, acuminate ; 

 leaves consisting of three leaflets, except the uppermost, 

 which are simple ; leaflets ovate or lanceolate, blunt, 

 with a short mucro, perfectly entire, ribbed by con- 

 spicuous lateral nerves ; racemes rather dense, on short 

 peduncles, axillary, solitary, twin or ternate, hardly 

 three times longer than the leaflets ; bractea nearly 

 round, acuminate ; pedicels ternate, several times 

 shorter than the calyx ; teeth of the latter acute, the 

 lowest a little longer than the rest; pod laxly enclosed in 

 the calyx, kidneyshaped ovate, compressed, rostellate, 

 covered with sessile scutellar glands, connate with the 

 seed. 



On the banks of the rivers Victoria and Nicholson. 



Stems several from each root, 5-10 feet high, flexible, 

 terete, without furrows, rarely branched, sometimes decum-

 petioles 1-2 inches long ; stipules 5-6 lines long ; leaflets 

 cuspidate, 1^-2^ inches long, f-1^ inches broad, with pinnate 

 nerves, grossly dotted with immersed glands, flat, of equal

 inside purplish, obscurely callous, with its deltoid unguis 4-5 

 lines long, surpassing a little the length of the wings and of

 basilar appendage, and a narrow unguis ; carina straight, 

 blunt, adherent to the wings, divided towards the base, white 

 with purple summit ; anthers round - didymous ; stamens
