Spec. Char., fyc. Leaf villose, 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., ii. p. 67.) 

 A native of sunny rocky spots in 

 the south of 

 Europe, from 

 Portugal to 

 Tauria. Fruit 

 villose. (Ibid.) 



Description ,$ c. 

 The general habit 

 of this plant re- 

 sembles that of Ii. 



typhina ; but it is much smaller in all its parts. The leaflets are about 2 in. long, 

 and | 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.

Spec. Char., §c. Leaf glabrous above, a little pilose beneath, of 5 — 7 pairs

Variety. 



m R. c. 2 leucdntha Jac. Hort. Schon., t. 342. — Root not stoloniferous. 

 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. 6'oriaria, 

 is somewhat winged towards its tip, 

 which, with other circumstances, in- £ 

 duces us to think that they may both 

 be varieties of the same species. 

 R. copallina is found in dry fields 

 anil 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-
