" The Hongkong wild kumquat grows commonly on the dry hills about 

 Hongkong and on the mainland of China opposite." (W. T. Swingle, 

 Jour. Wash. Acad. Set., vol. 5, p. 174-175, 1915.) 

 36986. Cudrania javanensis Trecul. 



" The fruit is round, rather more than an inch in diameter, of a bright 

 orange color, with a sweet, rather insipid taste. It is quite as good a 

 fruit as many others which are eaten." (Tutcher.) 



Distribution. — A shrub or small tree found in eastern Africa and in 

 India and eastward and southeastward to China and through the Malayan 

 Archipelago to Australia. 



36987. Carica papaya L. Papaya. 



From Manila, Philippine Islands. Presented by Mr. O. W. Barrett, chief, 

 Division of Horticulture, Bureau of Agriculture. Received January 13, 

 1914. 



" The Dapitan, or Singapore variety, recognized by us as distinct from the 

 Hawaiian variety." (Barrett.) 



36988 to 36990. 



From St. Denis, Island of Reunion. Presented by Mr. August de Villiles. 

 Received January 6, 1914. 



36988. Phaseolus calcabatus Roxb. Rice bean. 



" The rice bean is cultivated to a limited extent in Japan, China, India, 

 Mauritius, Java, and the Philippines. What is supposed to be the wild 

 original of this bean occurs in India. 



" The plant is strictly an annual and is half twining in habit. Planted 

 in rows, the different varieties grow 12 to 30 inches high and produce 

 vining branches 3 to 6 feet long. The leaves closely resemble those of the 

 common bean, but not infrequently are 3 lobed. The flowers are bright 

 yellow, produced in racemes of 10 to 20. The pods are smooth, slender, 

 falcate, straw colored, brownish, or blackish, 3 to 4 inches long, and burst 

 open readily at maturity. Though very productive of seed, the vining 

 habit of the plant, as well as the shattering, makes it difficult to harvest. 

 The flowers are self-fertile, as when bagged at Arlington Farm they set 

 pods perfectly. 



" Like other annual legumes, the later varieties are much larger in 

 growth than the early ones. The late ones are very vigorous in growth 

 and make a thick, dense mass of foliage. Such sorts may prove valuable 

 as cover crops in the South, but, unfortunately, they are all subject to 

 root-knot. This, together with the shattering of the seed, will always 

 militate against their extensive use. 



"The varieties differ mainly in their periods of maturity and in the 

 color of the seeds, which are straw-colored, brown, maroon, black, and 

 gray marbled.
