384 FOREST CULTURE AND 
Rhus typhina, L.— The Staghorn Sumach. North 
America, extending to Canada. This species will 
grow to a tree of 30 feet high. Its wood is of an or- 
ange tinge. Through incisions into the bark a kind 
of copal is obtained. The leaves can be used like or- 
dinary sumach. This bush can be reared on inferior 
land. 
Ribes aureum, Pursh.—Arkansas, Missouri, Ore- 
gon. This favorite bush of our shrubberies would 
likely on our forest-streams produce its pleasant ber- 
ries, which turn from yellow to brown or black. Al- 
lied to this is R. tenuiflorum, Lindl., of California and 
the nearest States, with fruits of the size of red cur- 
rants, of agreeable flavor, and either dark purple or 
yellow color. 
Ribes divaricatum, Douglas.—California and Ore- 
gon. One of the gooseberries of those countries. 
Berries smooth, black, about one third of an inch in 
diameter, pleasant to the taste. Culture might im- 
. prove this and many of the other species. R. Nut- 
talli (R. villosum, Nutt., not of Gay, nor of Wallich) 
is an allied plant, also from California. 
Ribes Floridum, l’Heritier.—The Black Currant of 
North America. The berries resemble in odor and 
taste those of R. nigrum. Allied to this is R. Hud- 
sonianum, Rich., from the colder parts of North 
America. 
Ribes Griffithi, J. Hook. and T. Thoms.—Himalaya 
at a height of 10,000 to 13,000 feet. Allied to R. 
rubrum, bearing similar but larger berries of somewhat 
austere taste. The naturalization of this currant-bush 
on our highest alps may prove of advantage. R. la- 
ciniatum, H. and T., is likewise a Himalayan species
