362 FOREST CULTURE AND 
Perennial. The root used in veterinary medicine. 
It contains, like that of the following species, the crys- 
talline peucedanin. $ 
Peucedanum Ostruthium, Koch. (Imperatoria Os- 
truthium, L.)—Mountains of Middle Europe. <A pe- 
rennial herb, which could be grown in our Alps. The 
acrid aromatic root is used in medicine, particularly 
in veterinary practice. It is required for the prepara- 
tion of some kinds of Swiss cheese. P. Cervaria, 
Guss., and P. Oreoselinum, Moench., are also occasion- 
ally drawn into medicinal use. 
Peucedanum. sativum, Benth. (Pastinaca sativa, 
L.) The Parsnip. Europe, North and Middle Asia. 
Biennial. The root palatable and nutritious. 
Phalaris Canariensis, L.—The Canary Grass. An 
annual grass from the Canary Islands, now widely 
dispersed as a spontaneous plant over the the warmer 
zones of the globe. Thus it has also become natu- 
ralized in Australia. It is grown for its seeds, which 
form one of the best kinds of feed for many sorts of 
small cage-birds. The flour is utilized in certain pro- 
cesses of cotton manufacture,-and liked for some kinds 
of cakes. The soil for the culture of the Canary grass 
must be friable and not too poor. It is an exhaustive 
crop. As allied, annual species of similar use, but 
mostly of less yield, may be enumerated: P. brachy- 
stachys, Link., from Italy ; P. minor, Retz, and P. 
truncata, Guss., from various countries at the Medit- 
erranean Sea. Other species, including some from 
Asia, are deserving of trial; but the perennial Brit- 
ish P. arundinacea, L., is too harsh to serve for whole- 
some fodder, nor does it furnish Canary seed. 
Phaseolus adenanthus, G. Meyer. (P. Truxillen-
