CROTALARIA, A NEW LEGUME FOR THE SOUTH 25 
wide, mostly emarginate, glabrous above, very fine sparse pubescence beneath ; 
calyx 5 mm. long, teeth slightly longer than the tube, minutely pubescent; 
eorolla yellow, 8-9 mm. long; pods 1-1.5 cm. long, 7 mm. wide; seed small, 
3 mm. long, light color, matures midseason; a native American species. 
Under cultivation this species, which has been tested in southern 
Florida only, has made a good growth, producing many stems 
which are very leafy. It is of good forage type and may have 
value for this purpose. 
Crotalaria retusa L. 
Plant erect, 3-6 decimeters high, sparingly or moderately branched; branches 
divaricate ; stems terete, with fine grayish pubescence; stipules small, setaceous; 
leaves simple, oblanceolate to obovate, 6-12 cm. long and 2-6 cm. wide, 
sessile, glabrous above, very fine pubescence beneath; flowers in lax terminal 
racemes, 15-20 cm. long; calyx 1.5 cm. long, the broad teeth exceeding the 
tube; corolla yellow, standard 2.5 cm. long, with purplish tinge, exceeding 
the calyx; pod linear oblong, 4 cm. long, 1 cm. wide, glabrous, turning black in 
weathering; seed large, 4-5 mm. long, light brown to almost black, matures 
in midseason. 
While having rather heavy stems and an open habit of growth, 
this species is very attractive when in flower. It blooms more or 
less continuously and flowers early in comparison with other species. 
It has little value as forage and on account of its small growth 
will probably be found inferior to many other species for cover-crop 
and green-manure purposes. It is a very profuse seeder. 
Crotalaria rotundifolia (Walt.) Poir. 
Plant perennial, prostrate, and comparatively small; stems 3-6 decimeters 
long, branched; stipules small, usually sagittate; leaves simple, oblong to 
oval, rounded at apex, somewhat narrowed at base, pubescent on both sides, 
15-20 mm. long, 7-12 mm. wide; peduncles long, 2-6 flowered; calyx 8 mm. 
long, the teeth somewhat longer than the tube; flowers yellow, 10 mm. long; 
pod 18-22 mm. long and 8-10 mm. wide, glabrous; seeds 2 to 3 mm. long, brown, 
matures midearly ; native American species, 
This species, producing a fair amount of seed, occurs commonly 
in the Southern States but has not yet been tested under cultiva- 
tion. 
Crotalaria sagittalis L. 
Plant annual or perennial, erect, comparatively small, 3-6 decimeters high; 
stems terete, pubescent; stipules small, sagittate; leaves simple, linear, oblong 
to oval, 2-6 cm. long and 4-15 mm. wide, pubescent on both sides; peduncles 
2-10 cm. long, 24 flowered ; flowers yellow, 8-12 mm. long, corolla equaling the 
calyx; pod 18-22 mm. long and 8-10 mm. wide, glabrous; seed small, 2 mm. 
long, brown, matures midlate; native American species. 
Under cultivation this species has made but small growth. 
Crotalaria spectabilis Roth.” 
Plant erect, 1-2 meters high, moderately branched, but heavy foliage makes 
plant appear dense; branches terete, suleate, nearly glabrous, never woody; 
stipules large, 2 cm. long, foliaceous; leaves simple, large, long obovate, 12-18 
em. long and 6-9 em. wide, glabrous above, finely pubescent beneath; racemes 
mostly terminal, 20-30 cm. long, lax, 30-40 flowered; calyx 12 mm. long, cam- 
panulate, teeth broad and as long as the tube; corolla 24 mm. long, yellow 
with purple tinge, standard and wings striate with light purple lines; pod 45 
em. long, 12-15 mm. wide, inflated, glabrous, becoming almost black with 
weathering; seed large, 5 mm. long, glossy black, matures midlate.
