EUCALYPTUS TREES. 3038 
Fagopyrum triangulare, Meissner. — In the Hima- 
layan 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 F. ovina. It is superior to rye-grass in produce 
and improves with age. F. arundinacea, Schreb., F. 
pratensis, Huds., and F, loliacea, Huds., are varie- 
ties of this species. 
Festuca Hookeriana, F. v. Mueller, —Alps of Aus- 
tralia and Tasmania. <A tall perennial grass, evi- 
dently nutritious, required to be tried for pastoral 
culture, and perhaps destined to become a meadow- 
grass of colder countries. 
Festuca ovina, .—Sheep-Fescue. Europe, North 
and Middle Asia, North America, found also in South 
America and the Alps of Australia and New Zealand. 
This species, like F. elatior, is obtainable with facility. 
F. duriuscula, L., and F. rubra, L., are varieties. A 
perennial grass, thriving on widely different soil, 
even moory and sandy ground. It yields a good pro- - 
duce, maintains its virtue, resists drought, and is also - 
well adapted for lawns and the swards of parks.
