Fagopyrum emarginatum, Babiugtou. 
Chinese and Hinialaian 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 an 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 F. esculentum apply also to 
T. Tataricum. 
Fagopyrum triangulare, Meissner. 
In the Himalaiau Mountains, ascending naturally to regions 
11,500 feet high. An annual. F. rotundatim, 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 sjiecies. 
The tallest follows rivers readily as far down as the tides 
reach. The ordinary form is well adapited for poermanent 
pastures, has tender leaves, produces excellent hay and is 
early out in the season. It can be mixed advantageously 
with F. ovina. It is superior to ryegrass in produce 
and improves with age. F. arundinacea, Schreb., F. 
pratensis, Huds. and F. loliacea, Hnds. are varieties of this 
species. 
Festuca Hookeriana, F. v. Mueller. 
Al])s of Australia and Tasmania. A tall perennial grass, 
evidently nutritious, required to be tried for p^astoral cul-
