126 FODDER AND PASTURE PLANTS. 



Geographical distribution: It is indigenous to all Europe, 

 except the most northern parts, southwestern Asia and northern 

 Africa. 



Habitat: It grows naturally in dry pastures, along roads and 

 paths, on hills and mountains and in open woods. 



Cultural conditions: Kidney Vetch makes a good stand on 

 sandy or gravelly soil too poor for most leguminous plants. It 

 reaches its highest perfection on land rich in lime. It bears extreme 

 drought without injury and is little affected by alternate freezing 

 and thawing. 



Agricultural value: In some parts of Europe, where the soil 

 is too poor for Red Clover, Kidney Vetch is quite valuable. It is 

 used for both hay and pasture and is relished by stock. The yield, 

 however, is rather low. Its suitability for Canada is not known. 



SAINFOIN {Onohrychis saliva Lam.) 



Plate 23; Seed, Plate 27, Fig. 37. 



Other English name: Esparsette. 



Botanical description: Sainfoin is perennial with a vigorous 

 taproot which becomes rather woody and much branched. The 

 stems are numerous, erect or ascending, and reach a height of from 

 one to two feet. The leaves are compound and generally consist of 

 a great number of leaflets, which, with the exception of the terminal 

 odd one, are in pairs along the midrib. The flowers are in a rich, 

 spike-like inflorescence which gradually becomes long and thin. The 

 flowers, which are very showy, are pink with darker veins. They 

 are rich in honey and allow the ordinary honey bee and other 

 insects to reach the bottom of the tube where the nectar is stored. 



Geographical distribution: Sainfoin is indigenous to tem- 

 perate Europe, from the Baltic in the north to the Mediterranean 

 in the south, from the Atlantic in the west to the border of Asia 

 in the east. It is also a native of southern Asia. 



History: Sainfoin has been cultivated in France for more than 

 four hundred years, whence its cultivation spread to other European 

 countries, especially Italy, England, Switzerland and Germany,
