 pubescent, climbing or trailing, 15 long or 

 less. Leaves long-petioled, leaflets ovate, 

 acute or acuminate, li'-4' long, the terminal 

 one equilateral and long-stalked, the others 

 inequilateral and short-stalked ; racemes 

 axillary, several-flowered, exceeding the

 gardens but not grown as a crop. Native of the 

 Old World tropics, widely cultivated and natural- 

 ized in tropical and temperate America. Flowers 

 in Bermuda in autumn. 



Dolichos sphaerospermus (L.) DC., 

 BLACK-EYED PEA, is recorded by Reade as 

 cultivated in summer and by H. B. Small as 

 frequent in fields ; I have not met with it.
