S. P. I. No. 
32643. From the same source as No. 32640. Growth and maturity just like No. 
32640; seeds grayish green, finely marbled with black specks. 
32644. From the same source as No. 32640. Indistinguishable in growth from No. 
32640; seeds straw colored. 
33098. From Cuba, 1912. “Little Devil or mambi bean. An indigenous legume, 
found growing wild in the woods of Oriente Province, especially in the valley 
of Guantanamo. A climbing vine of vigorous growth that covers and smothers 
the tree over which it grows; for this reason the native country people call 
it ‘Little Devil.’ It is also called ‘mambi,’ because it was discovered as 
edible by the Cuban soldiers during the war of 1868-1878.”’ Very late, not 
even blooming at Arlington farm in 150 days in 1912 when killed by frost. 
Vines vigorous, making a solid mass 2 feet deep, but not quite so large as No. 
21291; seeds maroon. 
01555. From Mr. E. T. Shields, Yachow, China, March, 1911. ‘‘This bean is known 
as climbing mountain bean. It is fed to pigs and not much eaten by the 
natives.’ Vines in rows 16 inches high, 30 inches broad, in full bloom at 
Arlington farm in 120 days, a few pods maturing when killed by frost at the 
end of October. 
THE MUNG BEAN, GREEN GRAM, OR GOLDEN GRAM. 
The mung bean (Phaseolus aureus Roxb.; Pls. IV and V) is culti- 
vated throughout the southern half of Asia, in the adjacent Malayan 
Islands, and quite generally through the eastern portions of Africa. 
It has been introduced into Greece, but otherwise seems not to be 
cultivated in Europe. In India the plant is of very ancient cultiva- 
tion, and numerous varieties are found in different parts. The plant 
is not definitely known in a wild state, but Prain (1897, p. 423) is in- 
clined to think that it is a cultivated derivative of Phaseolus radiatus 
L. (Phaseolus sublobatus Roxb.), which grows wild in India. Accord- 
ing to Mollison (1901, p. 87) this legume, or pulse, is sixth in impor- 
tance in the Bombay Presidency, about 200,000 acres being grown 
each year, mostly mixed with other crops. The seeds are used almost 
exclusively as human food and the straw is fed to cattle. Duthie 
and Fuller (1882, p. 37) state that the average yield of seed per acre 
is 410 pounds. In the Northwestern Provinces and Oudh it is more 
important than the urd bean, the moth bean, or the cowpea. 
In German East Africa it is called chiroko, and the same name is 
used in Portuguese East Africa. In Japan its name is bundo or 
yayenari. In Jamaica both the mung and the urd have been intro- 
duced by Hindoo laborers. The plant is there called Jerusalem pea 
and is being used largely as a green-manure crop (Harris, 1913, p. 
192). 
BOTANY. 
There has been great confusion concerning the proper botanical 
name to apply to the mung. Most of the difficulties in the case have 
now been cleared up, thanks to the generous assistance accorded by 
Sir David Prain, director of the Royal Botanic Gardens at Kew. The
