Crotalaria mysorensis Roth. 
Plant 1-9 decimeters high, erect, moderately branched; stems terete, densely 
silky with long hairs; stipules linear, foliaceous, persistent, 2-38 cm. long; 
leaves simple, linear-oblong to long ovate rounded at the apex, 5—7 ecm. long, 
1.5-2 em. wide, clothed with long silky pubescence; racemes terminal and 
lateral, 15-20 cm. long, few flowered; calyx 15-20 mm. long, teeth long, acumi- 
nate, and extending nearly to the base; corolla yellow, not exserted; pod 
oblong, 3.5 em. long by 2 em. wide, inflated; seed 3 mm. long, dark brown or 
nearly black, matures midlate. 
This rather coarse species has made too little growth to suggest 
any special value. At Columbia, S. C., it has bloomed the last of 
July and ripened seed by the middle of October. At Gainesville, 
Fla., it has been somewhat earlier. At both places it has set a fair 
amount of seed. 
Crotalaria natalitia Meissn. 
Plant upright, 1-2 meters high, openly branched; stems terete, lightly sul- 
cate, very finely pubescent; leaves trifoliolate, the central leaflet longer than 
the laterals and linear to linear obovate, up to 4 cm. long and 1 em. wide, 
glabrous above, sparingly pubescent beneath; stipules foliaceous, 1—-1.5 em. 
long, acuminate; flowers 1—4 on lateral stems or few in terminal lax raceme; 
calyx glabrous, very broadly campanulate, 7-8 mm. long, teeth broadly dentate 
and slightly shorter than the tube; corolla 15 mm. long; wings and standard 
quite wide and nearly of equal length, tinged with purple and somewhat stri- 
ate; pod inflated, 3.5 cm. long and 10-12 mm. wide, glabrous; seed 4 mm. 
long, brown, matures late. 
This species has made good growth, but it has not been tested 
sufficiently to determine its value. Its late season of maturing 
makes seed production uncertain. At Gainesville, Fla., and other 
places where it has been tested, it has not come into bloom until 
after the first of October and has matured comparatively little seed. 
Crotalaria oocarpa Baker. 
Plant semidecumbent, bushy, 6-9 decimeters high; stems with dense midlong 
rufous pubescence; stipules very small, setaceous; leaves trifoliolate; leaflets 
up to 5 cm. long and 2 cm. wide, narrowed at the base and with pointed apex, 
densely pubescent or villous on both sides; flowers in dense terminal racemes; 
calyx villous, 6 mm. long, the wide teeth about equaling the tube; corolla 12-15 
mm. long, yellow, standard and wings purple or purple striate, standard pubes- 
ate; pod inflated, 3.5 cm. long and 10-12 mm. wide, glabrous; seed 4 mm. long, 
brown, matures late. 
This species has been grown in Florida only, maturing seed at 
Coconut Grove, in the southern part of the State. Its general habits 
and growth suggest that it may have value as a cover crop. 
Crotalaria polysperma Kotschy. 
Plant erect, 9-12 decimeters high, divaricately branched; stems densely 
rufo-villous; stipules linear or setaceous; leaves trifoliolate, leaflets oblong 
ovate, tending to be acute at both ends, finely pubescent on both sides; 
racemes lax, 2-8 flowered; calyx 1.5-2 cm. long, teeth twice as long as tube; 
corolla yellow, standard lightly striped purple and densely silky on the back, 
as long as the calyx; pod 34 cm. long, brown, matures midlate. 
While making a fairly large growth, this species is not so vigor- 
ous as many others and appears as a comparatively hight producer 
of both forage and seed. 
Crotalaria pumila Ortega. 
Plant perennial, decumbent to semierect, moderately to profusely branched ; 
stems 35-6 decimeters long, terete, branched, nearly glabrous; stipules small; 
leaves trifoliolate; leaflets narrowly obovate to cuneate, 1-2 cm, long, 7--9 mm,
