282 DECANDRIA. MONOGYNIA. 



long, in which particular it strikingly drffers from eve- 

 ry otiier known species; stipules small, linear-lanceo- 

 late, acute; legume small with a subulate point. Hab. 

 ?n Norih Carolina, principally upon the Catawba ridge, 

 where it occurs abundantly in the open bushy forests. 7. 

 *leiicop]icca. Dichotomous stem and nerves a little villous; 

 leaves ternate, sessile, rhomboidally obovate; stipules and 

 bractes ovate, acute, large and foliaceous; racemes late- 

 ral, many-flowered; flowers secund; legume acuminated. 

 Hab. In Georgia and Louisiana. (Abundant around St. 

 Louis.) Somewhat allied to P. ccerulea, but very distinct. 

 A large species with ochroleucous flow^ers, in long and 

 dense spikes, larger than those of any other North Ame- 

 rican species. Stem rather low but divaricate, leaves 2 

 inches long and an inch broad, obtuse. 8. mictoria. So 

 called from having been formerly employed as a substi- 

 tute for indigo, all the genus probably possess this pro- 

 perty in different degrees, though there is something pe- 

 culiar in the structure of this plant. Calix about 4-tooth- 

 ed, the 2 uppermost of the 5 cohering into one, wings 

 each furnished with a callosity at the lateral tooth. 



A North American genus; the simple leaved species of 

 the Cape of Good Hope being alone retained in Podaly

Ca/i.x subcampanulate, half 4-cleft., the upper 

 segmont truncate and emarginate. Corolla pa- 

 pilionaceous, petals nearly equal in length; vex- 

 ilium reflected at the sides; canna obtuse. Le- 

 gume compressed and falcate, attenuated at the 

 base, many-seeded. 



Herbaceous; leaves ternate petiolate, stipules large and 

 foliaceous; spikes terminal, interrupted, subverticillate, 

 erect; flowers yellow. Very distinct in habit from Cytisus 

 but requires further comparison with that genus? 



Species \.* rhombifoUa. Leaflets rhombic-ovate, sub- 

 cuneate, under side somewhat silky pubescent; stipules fo- 

 liaceous, obliquely ovate, shorter than the petiole; raceme 

 interrupted. Ctjtisus rhombifoUns^ T. N. in Fras. Catal. 1813.
