and Gainesville, Fla., it has been in bloom the first half of August 
and ripened seed the last of September. ; 
Crotalaria incana L. 
Plant erect, 6-18 decimeters high, divaricately branched, but forming a rather 
bushy plant; stems clothed in fine silky hairs; stipules very small; leaves 
trifoliolate; leaflets broadly obovate to nearly oval, up to 34 em. long, 2-2.5 
cm. broad, glabrous above, sparse silky pubescence beneath; flowers yellow, 
15 mm. long, about half again as long as the calyx; calyx teeth about three 
times as long as calyx tube; pod linear oblong, 32-85 mm. long and 8-10 mm. 
wide, turgid, clothed with spreading hairs; seed large, 4.5 mm. long, greenish 
brown to dark brown; matures midearly. 
The stems of this species seem a little woody for the best forage. 
However, it makes a good growth, is well adapted to a wide range 
of conditions, and is a free seeder. At Gainesville, Fla., it has been 
in bloom the last of May, ripening seed in July. At Columbia, 
S. C., it has been about a month later. The main crop of seed matures 
somewhat later than the dates given. 
Crotalaria intermedia Kotschy. 
Plant erect, 9-18 decimeters high, moderately branched, stems terete, sub- 
glabrous; stipules wanting; leaves trifoliolate; leaflets linear, glabrous above, 
subglabrous below; 8-14 cm. long, and 1—-1.5 cm. wide; racemes lax, terminal, 
15-80 cm. long; flowers up to 2 cm. long, yellow, the standard conspicuously 
veined with purple; calyx 5 mm. long, broadly campanulate, subglabrous; calyx 
teeth shorter than the tube; pod large, 5 cm. long, 1.5 cm. broad, inflated, 
little or no pubescence; seed 3 mm. long, mostly very light color, matures mid- 
late. 
At all the stations where this species has been tested it has made 
a good growth and volunteers readily. It is not so leafy as Crotalaria 
grantiana or C. maxillaris and is somewhat coarser than those species. 
It makes a good growth farther north than (@. striata, is a good seed 
producer, and has fairly good seed habits. At Gainesville, Fla., it 
has bloomed in July and August and ripened seed in August and 
September. In Georgia and South Carolina it has not ripened seed 
until October and November. 
Crotalaria juncea L. 
Plant erect, 2-4 meters tall, but little branched, often single upright stalks 
with no branches; stems terete, suleate, with silvery gray pubescence; stipules 
none or very small; leaves simple linear or linear oblong, very finely pu- 
bescent on, both sides, averaging up to 12 cm. long and 2 cm. wide; racemes 
lateral and terminal, lax, 12-20 flowered; calyx 2 em. long, densely clothed 
with fine pubescence, teeth extending nearly to the base; flowers large, 3 cm. 
long, yellow; pod 38 cm. long and 1 cm. wide, inflated, clothed in dense fine 
pubescence; seed large, 4-5 mm. long, light to dark brown, matures very late. 
This species is very variable, some varieties being much more 
branched than others. It is too coarse for good forage but makes a 
good green-manure plant. In India and adjacent tropical regions 
it is used for fiber as well as green manure. While it blooms from 
midsummer on, it sets no seed pods until late fall. It is a very sparse 
seeder under conditions in the United States. 
Crotalaria lanceolata HW. Mey. 
Plant erect, 7-12 decimeters high, well branched; stems small, terete; leaves 
trifoliolate; leaflets linear, 4-8 cm. long, 6-8 mm. wide, tip obtuse or rounded, 
mucronate, glabrous above, sparingly pubescent beneath; stipules none; flowers 
in long terminal racemes; calyx tube broadly campanulate, 3 mm, long, lightly
