270 FOREST CULTURE AND 
graves. Industrially, it interests us on account of its 
powerfully-fragrant blossoms, for the sake of which 
this bush will deserve to be cultivated. The scent 
might be extracted by Mr. Bosisto’s process. 
Borrago officinalis, L.—South Europe, Orient. An 
annual herb, occasionally used for medicinal purposes 
or as an admixture to salad. 
Brabejum stellatifolium, L.—South Africa. The 
nuts of this shrub are edible, resembling those of our 
Macadamia ternifolia, to which also in foliage and 
flowers Brabejum is closely allied. The nuts are also 
similar to those of the Chilian Guevina Avellana. 
Brassica alba, Visiani. (Sinapis alba, L.)—White 
Mustard. Europe, North Africa, North and Middle 
Asia. Anannual. The seeds are less pungent than 
those of the Black Mustard, but used in a similar man- 
ner. The young leaves of both are useful as a cu- 
linary and anti-scorbutic salad. Dr. Masters enumer- 
ates Brassica Chinensis, B. dichotoma, B. Pekinensis, 
B. ramosa, and B. glauca, among the mustards which 
undergo cultivation in various parts of Asia, either 
for the fixed oil of their seeds or for their herbage. 
From 15 lbs. to 20 Ibs. of seeds of the white mustard 
are required for anacre. In the climate of California, 
similar to ours, 1,400 lbs. of seeds have been gathered 
from an acre. 
Brassica nigra, Koch. (Sinapis nigra, L.)—The 
Black Mustard. Europe, North Africa, Middle Asia. 
An annual. The seeds, simply crushed and then sift- 
ed, constitute the mustard of commerce. For med- 
icinal purposes the seeds of this species are preferable 
for sinapism and other purposes. In rich soil this 
plant is very prolific; and in our forest-valleys it is
