Fagopyrum emarginatum, Babington. 



Chinese and Himalaian Mountains, where it is cultivated 

 for its seeds. Annual. 



Fagopyrum esculentum, Moench. 



Central Asia. The ordinary Buck- "Wheat. This annual 

 herb succeeds on the poorest soil. The crushed amylaceous 

 seeds can be converted by boiling or baking into a palatable 

 and wholesome food. As au agrarian plant it can with 

 advantage be raised as a first crop on sandy heath-land, 

 newly broken up, for green manure. The period, required 

 for the cyclus of its vegetation, is extremely short. Thus it 

 can be reared on our higher Alps. 



Fagopyrum Tataricum, Moench. 



Middle and North Asia. Yields for the higher mountain 

 regions a still safer crop than the foregoing, otherwise the 

 remarks offered in reference to E. esculentum apply also to 

 T. Tataricum. 



Fagopyrum triangulare, Meissner. 



In the Himalaian Mountains, ascending naturally to regions 

 11,500 feet high. An annual. F. rotundatum, Babington, 

 seems a variety of this species. It is cultivated for food 

 like the rest. 



Festuca elatior, L.* 



The Meadow Fescue. Europe, North Africa, North and 

 Middle Asia. A perennial grass, attaining a height of 

 several feet. There are several varieties of this species. 

 The tallest follows rivers readily as far down as the tides 

 reach. The ordinary form is well adapted for permanent 

 pastures, has tender leaves, produces excellent hay and is 

 early out in the season. It can be mixed advantageously 

 with E. ovina. It is superior to ryegrass in produce 

 and improves with age. F. arundinacea, Schreb., F. 

 pratensis, Huds. and F. loliacea, Huds. are varieties of this 

 species. 



Festuca Hookeriana, F. v, Mueller. 



Alps of Australia and Tasmania. A tall perennial grass, 

 evidently nutritious, required to be tried for pastoral cul-
