CROTALARIA, A NEW LEGUME FOR THE SOUTH 3} 
lets. The branching varies with the species. Some have an upright 
central stem with little or no branching, while others are very pro- 
fusely and finely branched. The species that have been used agri- 
culturally are large, upright, and diffusely branched, with the ex- 
ception of Crotalaria juncea, which is sparingly branched. (Figs. 
1 and 2.)

Some species, such as Crotalaria retusa L. and C. lanceolata K. 
Mey., mature a considerable quantity of seed early, within 100 to 
140 days from the planting date. Many others are too late to mature 
seed, even under Florida conditions. C. striata and C. spectabilis 
Roth? represent an intermediate type as regards maturing seed, 
requiring 125 to 175 days before many pods are mature. Most spe- 
cles continue to set pods and mature seed all summer and fall, 
* Crotalaria sericea Retz. is a synonym of C. spectabilis Roth. The latter name is used 
preferably in accordance with botanical nomenclatorial rules.
