Cult. This genus contains plants of no beauty, and are there- 

 fore not worth cultivating, unless in botanical gardens. The 

 annual species should be treated like the species of Zornln. 

 The shrubby and perennial herbaceous kinds like other stove 

 plants. They are all most easily increased by seeds.

 bond ; in reference to the stamens being free). D. C. ann. sc. 

 nat. 4. p. 94. Jan. 1825. legum. mem. vii. prod. 2. p. 318. 



LIN. SYST. Decdndria, Alonogynia. Calyx 5-cleft, with the 

 segments acute and nearly equal. Corolla papilionaceous. Vex- 

 illum complicated above the rest of the petals when young. 

 Keel curved and truncate at the apex. Stamens distinct, ap- 

 proximate. Legume compressed, transversely many-jointed, 

 having the upper suture straight and thickish, but the kiwer 

 suture is sinuately lobed ; joints 1 -seeded, nearly orbicular, at 

 length separating from each other. Seeds compressed, reni- 

 formly orbicular. South American herbs, with lanceolate sti- 

 pulas, abruptly pinnate leaves, ending in a bristle, axillary, 1- 

 flowered pedicels, or the flowers are disposed in something like 

 racemes at the tops of the branches, in consequence of the upper 

 leaves being abortive. Dr. Hooker's arrangement of the species 

 of this genus is here adopted. 



SECT. 1. A'NNU^E. Annual herbs, having the lower flowers ax- 

 illary, solitary, and pedicellate, but the upper ones form a panicle 

 at the tops of the branches, in consequence of the upper leaves 

 being abortive. Flowers yellow. The plants contained in this 

 section have the habit of Smithia.

 cels axillary, and also disposed in terminal racemes ; legumes
