AGRICULTURAL VARIETIES OF THE COWPEA, ETC. 



intense violet, as may be seen in extracted solutions of the color as 

 well as in immature seeds. Seven cowpea varieties have their seeds 

 wholly or more or less clouded with violet, namely 21006, 

 22930, 24341C, 25965D, and 29277. All of these except the first are 

 from South Africa, and all but the last very vigorous, late, procum- 

 bent sorts. One variety 21006A has its seeds violet and finely 

 speckled with blue. 20980C has violet-eyed seeds and 2098OD has 

 violet -blotched seeds. All are coAvpeas. 



Smoky-gray seeded varieties. — Only two scarcely distinguishable 

 cowpea varieties have seed coloration described as smoky gray. Wat- 

 son 17425 and Sport 17427, neither of much value. This color ap- 

 pears in hybrids of Black and Blackeye. The same color has been 

 observed in catjang seeds, but they were not viable. 



Brown-seeded varieties. — Four varieties have their seeds burnt 

 umber in color, namely, Brown Coffee 17404, 17398A, 25512B, and 



29284. The first three are closely similar and of moderate value. 

 Asparagus bean 22648 has seeds of walnut-brown color. 



Black-seeded varieties. — Black-seeded varieties are but little less 

 numerous than buff-seeded. This color also occurs in all three 

 species. Among cowpeas the following black-seeded ones are 

 crowders: Black Crowder 22052, Wight Black Crowder 17372 and 



29285. Noncrowders include Chinese Black 16796, Early Black 

 17336, 17405F, 20980A, 21508, 21511, 21817, 22718B, 26399, 27549, 

 29292, and 29302. 



Black-eyed varieties are also abundant and as a rule they are 

 very similar to each other. Among them are 16167A, 17329, 17335, 

 17346, 17366, Blackeyed Lady 17420, 20980, 21297, 21510, 21537, 

 21815, 22050, 22382, 24190, 24191, 24566A, 25016. 27504, 27548, 29276, 

 and 29299. Black-eyed varieties have always been grown as a table 

 vegetable since ancient times, which accounts to some extent for the 

 numerous very similar varieties. With black-blotched seeds are 

 Holstein 17327, 21297A, 24188, 24566C, 29280, and 29309. 



Black catjangs are not numerous, only three varieties, 21295C, 

 21297E, and 27502, having been obtained. Two others, 21293D and 

 21295F, have black-blotched seeds. 



Asparagus beans have black seeds in four varieties, 6311. 6567, 

 17332, and 20006. One variety grown only a single season, 01422A, 

 has black-blotched seeds. 



Marbled-seeded varieties. — The marbled type of coloration, repre- 

 sented by the well known Whippoorwill, occurs in catjangs and as- 

 paragus beans as well as in cowpeas. Among the cowpeas in this 

 group with the seed wholly marbled are Whippoorwill 17349, Whip- 

 poorwill Crowder 17371, Red Whippoorwill 17374, Brabham 21599, 

 Peerless 25314, Chinese Whippoorwill 17330, 17849, 21085, 23307,
