farther north. It is a very sparse seeder under Florida conditions 
and too coarse for best forage. 
Crotalaria astragalina Hochst 
Plant erect, up to 6 decimeters high; stems small, subglabrous; stipules none; 
leaves trifoliolate; leafiets linear, +7 cam. long, 5 mm. wide, glabrous above, 
subglabrous beneath; flowers in short terminal and lateral racemes; calyx 3 
mm. long, sparingly pubescent, the teeth about equaling the tube; corolla 
S mm. long, the standard striate with heavy purple lines, the tip appearing 
almost solid purple: pod long oval or cylindrical, 2 cn. long ard 6 mm. wide, 
finely pubescent; seed 2 mm. long, light color, matures laie. 
_ This is a small-growing plant which has been grown at Gaines- 
ville, Fla., only, and appears to be of inferior value. 
Crotalaria axillaris Dryand. 
Plant erect, 3-9 decimeters high, moderately branched: stems finely puberu- 
lent; stipules very small or wanting; leaves irifoliolaie on long petioles, up 
to 7 am. long and 3 em. wide, glabrous above, sparsely pubescent beneath; 
fiowers large, 20 mm. long, yellow, finely siriped wiih purple lines, single in 
leaf axils, the terminal clusiered: calyx tube very broad, 3 mm. long; calyx 
teeth dentate, 6 mm. long; pod large. up ito 5 am. long, sparsely pubescent; 
seed 3 mm. long, mosily light brown, matures Iaie. 
This species has been grown in the open at McNeill, Miss. While 
not so iree a grower as some others, it may be of some importance, 
and further tests should be made. 
Crotalaria calycina Schrank. 
Plant semiprostrate to semierect, 3-6 decimeters high, sparingly branched: 
stems densely pubescent; stipules very small; leaves simple, long linear, 10-11 
' gm. long by 15 am. wide, glabrous above, pubescent beneath; fiowers large, 
20 mm. long, pale yellow, turning brown on drying, entirely inclosed; calyx 
large, clothed in long brown pubescence; teeth linear, 20-25 mm. long, divided 
io the base; pods small, inflated, obovate, glabrous, 15 em. long, inclosed; 
seed small, 225 mm. long, lighi color, matures laie. _ 
The small growth made by this species limits its possible use. It 
has been grown only in southern Florida, where it may have possible 
value as a cover-crop plant. No seed matured at Coconut Grove, Fla. 
Crotalaria candicans Wighi and Arn. 
Plant erect up to 3 meters or more in height, freely branching; stems stifi, 
Glothed with dense brown pubescence; siipules none; leaves simple, short 
petioled, large, 10-12 cm. long and +6 cm. wide, fime dense silky pubescence 
on both sides; calyx 12 mm. long, deeply bilabiate, tecth acuminaie to lanceo- 
late; flowers exserted, 25 mm. long; standard densely silky on the back: pod 
25 em. long, subsessile, nearly glabrous; seed large. 5 mm. long, lighi to dark 
brown, matures very laie. 
A good growth has been made by this species in both southern 
Florida and southern Mississippi. It requires a very long season. 
No seeds were developed at McNeill, Miss. The stems are too coarse 
for good forage but make good green manure. 
Crotalaria capensis Jacq. 
Plant 6-20 decimeters high, erect, branching freely; stems hard with age, 
round, subglabrous; stipules deciduous; leaves trifoliolate; leaflets obovaie, 
up to 2-3 em. long, both sides nearly glabrous; flowers large. yellow. 15 mm. 
long, 6-20 in lateral and terminal racemes; calyx tube 5 mm. long; calyx teeth 
6-8 mm. long; pod distinctly stalked, 3-4 cm. long, 6-7 mm. thick: seed 5 mm. 
long, brown, matures very late.
