develop straight robust annual flowering shoots from a perennial woody 
rhizome, the flowers, which are invariably yellow, being variously 
disposed. 
I. Annual flowering shoots rigid, straight, and erect. 
iFlowers congested in hemispheric or oblong heads. 
*Leaflets thickly and densely ferruginously hirsute- 
sericeous. 
Leaflets elliptic, subacute ; lateral nerves prominent but 
the intervening veinlets inconspicuous. Vexillum 
slightly sericeous posticously (4) holoscricea. 
Leaflets narrowly obovate, rounded at the apex, promi- 
nently netted beneath. Vexillum glabrous (5) Bolusii. 
**Leaflets sparingly sericeous or pubescent. 
Leaves densely imbricate. Heads many, densely- 
flowered. Habit robust (1) cajanifolia. 
Leaves scarcely imbricate. Heads few, 2-3-flowered. 
Habit slender (3) gracilior. 
iiFlowers disposed in paniculately branched spiciform racemes. 
Leaflets thickly hirsute-sericeous, elliptic-acuminate. .. (2) jjaniculata. 
II. Annual flowering shoots decumbent, sinuate. 
a. Stipules filiform or subulate. Spiciform racemes com- 
pactly flowered. 
fLeaflets elliptic, 7 cm. long, thickly coriaceous, and 
densely ferruginously sericeous (7) viacrophylla. 
tfLeaflets obovate, 3 cm. long, thinly coriaceous, with 
scattered hairs, prominently veined and buUatulate. . . (6) obovata. 
b. Stipules obliquely ovate, cuspidate. Eacemes elongate, 
often secund, more or less laxly flowered. 
*Pedicels 1-1^ mm. long. Bracteoles subulate, incon- 
spicuous (8) grandifolia. 
**Pedicels 3-4 mm. long. Bracteoles broadly ovate or 
reniform, cuspidate, enveloping the lower portion of the 
calyx (9) latebradeolata.
