Spec. Char., §c. Leaf vyillose, of 
5—7 pairs of leaflets, and the odd 
one ; leaflets elliptical, and toothed 
with large and blunt teeth. The 
petiole smooth at the tip, a little 
margined. (Dec. Prod., li. p.67.) 
A native of sunny rocky spots in 
the south of 
Europe, from 
Portugal _ to 
Tauria. Fruit 
villose. (Zbid.) 
Description, §c. 
The general habit 
of this plant re- 
sembles that of R. 
typhina ; but it is much smaller in all its parts. The leaflets are about 2 in. long, 
and 4 in. wide, of a pale green, serrated, and in general appearance resembling 
the leaves of the common elm. The flowers are in large loose panicles, of a 
whitish green ; and they appear in July, but are seldom followed by seeds in 
England. The seeds are used at Aleppo, ground into powder, as a provocative 
to appetite, as mustard is in Britain. The plant is a native of the south of 
Europe and the north of Africa, and it appears to have been introduced into 
England in 1640. In British gardens, this species is not uncommon. Plants, 
in London, cost Is. 6d. each; at Bollwyller, 1 franc.

Flowers whitish. Panicles more contracted than in the species. 
Description, §c. The leaves and 
general habit of the plant are those 
of R. typhina, but it seldom grows to 
the height of more than 4 ft. or 5 ft. 
The branches are smooth, and the 
leaflets entire with acute points ; 
they are light green on both sides, 
and in autumn change to a fine pur- 
ple. The petiole, as in R. Coriaria, 
is somewhat winged towards its tip, < 
which, with other circumstances, In- 4 
duces us to think that they may both 
be varieties of the same species. 
R. copallina is found in dry fields 
and woods, particularly in sandy 
soil, from New Jersey to Carolina. 
The leaves are used as tobacco by 
the Indians of the Missouri and the 
Mississippi. The species was intro-
