S. P. I. No. 



21708. From Amraoti, India, in 1907, under the name "urid." A late, vigorous 

 variety at Arlington farm growing 20 to 24 inches high and 3 feet broad. At 

 the end of 141 days, when nipped by frost, just beginning to bloom. Seeds 

 black and gray marbled. Apparently the same as No. 21790. 



21789. From the Botanic Gardens, Calcutta, India, 1908. Grown at Arlington farm 



in 1908 and 1912. Plants 12 to 18 inches high, 2 feet broad; 40 per cent of 

 the pods mature in 100 days, 80 per cent in 120 days; pods straw colored; 

 seeds olive. 



21790. From the Botanic Gardens, Calcutta, India, in 1908, as "Phaseolus pilosus." 



Grown at Arlington farm for several seasons. A very sprawling, late variety, 

 the plants 20 to 30 inches high and 3 feet broad. Begins to bloom in about 

 140 days. At Gainesville, Fla., matured a few pods in 1909, but was badly 

 affected both by wilt and root-knot. Seeds black and gray marbled. Prob- 

 ably the same as 5438. 



25516. From Gobindapur, India, 1909. Seeds black and gray marbled. No field 

 notes. 



25705. From Poona, India, 1909. Plants 12 inches high, 3 feet broad, blooming in 100 

 days, but no pods maturing seeds. Seeds black and gray marbled. 



26360. From Malkapur, India, 1909. Seeds black and gray marbled. No cultural 

 notes. 



28765. From Port of Spain, Trinidad, 1910. "Woolly pyrol." Grown at Arlington 

 farm in 1912. Plants 16 inches high, sprawling, 3 \ feet wide. No blossoms 

 when killed by frost. Seeds gray and black marbled. 



32607. From Darjiling, India, 1911. Late, not blooming in 1913. Plants large, 30 

 inches wide, 15 inches high. Seeds shining, black and olive marbled. 



34363. Seeds rather small, gray and black marbled. 



THE MOTH BEAN. 



The moth bean (Phaseolus aconitifolius Jacq. ; PL VII) is cultivated 

 as a crop only in India. It is at once distinguished from any other 

 cultivated bean by the leaflets being divided into narrow lobes. 

 What is doubtless the wild original occurs both in India and Ceylon. 



The moth is apparently more important in India than the mung or 

 urd. According to Mollison (1901, p. 86) an area of 300,000 acres 

 is grown in Bombay. Duthie and Fuller (1882, p. 41) give the area 

 in the Northwestern Provinces and Oudh as 211,000 acres. This 

 bean is nearly always planted mixed with other crops. 



The plants produce numerous slender, decumbent branches from a 

 short stem, a well-grown plant making a dense mass 18 to 24 inches 

 in diameter and 12 to 15 inches high. In none of the varieties grown 

 is there any tendency of the branches to twine. The seeds are linear, 

 straw colored, nearly smooth; pods 1 to 1.3 inches long, 5 to 7 seeded. 



In eight lots of seed secured from India the seeds were the same in 

 all, buff colored, but occasional seeds were marbled with black. 

 These last bred true as to seed color, but the plants were apparently 

 identical with those bearing buff-colored seeds. Occasional plants 

 have leaves with fewer lobes. These are the only variations that have 

 been noted in this bean.
