MANUAL OF POISONOUS PLANTS 



Prof. N. E. Hansen through his exploration has brought into prominence 

 the yellow-flowered alfalfas from Siberia, Medkago rulhcnica and M. platy- 

 carpa, and some of the hardy alfalfas are apparently hybrids between M. sativa 

 M. falcata. C. V. Piper* calls attention to a number of valuable leguminous for- 

 age plants that should be cultivated in this country, such as the Lyon bean 

 (Stisolobiitm Lyoni). The Kudzu (Puerana Thunbergiana) a woody native 

 of Japan, is much used as a forage plant in that country and has been culti- 

 vated in Florida. The Guar (Cyamopsis tetragomoloha) is an East India 

 annual legume and is said to be very drouth resistant. Tangier pea {Lathyrus 

 tingitanus) is a native of Northern Africa. It is excellent and said not 

 to be poisonous like the other species. The moth bean (Phaseolus aconiti- 

 folius) is used for food in India and is said to be a splendid 

 forage plant. The Adzuki bean (Phaseolus angularis) native of 

 southern Asia is used for food in China, Japan and India, and is said 

 to possess vaulable qualities as a hay plant. The Kulti (Doliclios bijiorus) 

 native to India is said to give promise in the semi-arid regions in Texas as 

 a valuable forage plant. Under the Vetches the more recent introductions 

 that give promise are the scarlet vetch (Vicia fulgens) of Northern Africa, 

 the black purple vetch {V. atro purpurea) of Algeria and the woolly pod 



Fig. 286. Carobtree, or St. John's Hrcad (CeviUonia 

 siliqua). The fruit is edible and is siip|iosed to be 

 the "locust" of Biblical histoiy. (.After Faguet.)
