Cult. The hardy shrubby species, such as fine varieties of com- 
mon Wallflower, should be encreased by young cuttings, which 
will soon strike root; if planted under a hand glass. ‘The green- 
house or frame kinds will thrive well in a light rich soil; and 
young cuttings planted in the same kind of soil, will strike most 
freely under a hand glass. The perennial or herbaceous species 
may be increased by dividing the plants at the root, by young 
cuttings planted under a hand glass, or by seeds. The biennial 
and annual species, only require to be sown in the open border ; 
some of the tenderer sorts, or those natives of warmer climates, 
may be sown in a gentle hot bed in the month of March, and 
transplanted into the open borders about the middle or end of 
April. The whole of the species answer well to be planted or 
sown on rock-work, and even the tenderer species will survive 
the winter in such a situation. 
III. NASTU’RTIUM (from nasus, the nose, and tortus, tor- 
mented ; acrid taste of N. officinale, which affects the muscles of 
the nose.). R.Br. in hort. kew. ed. 2. vol. 4. p. 109. D. C. 
syst. 2. p- 187. prod. 1. p. 137. but not of Haller and Moench. 
Lin. Syst. Tetradynamia, Siliqiosa. Silique nearly cylin- 
drical, short or declinate. Stigma somewhat two-lobed. Calyx 
equal at the base, spreading. Seeds small, not margined, dis- 
posed in two irregular series. Herbs usually aquatic, smooth, 
branched, easily rooting. Stems cylindrical. Leaves variable, 
usually pinnately-cut. Racemes many-flowered, without bracteas ; 
pedicels filiform. Flowers white or yellow. Siliques generally 
declinate. This genus differs from Szsymbrium, which it is very 
much like, in the cotyledons being accumbent, not incumbent. 
Sect. I. Carpa’minum (from capéca, kardia, the heart, and 
apaw, damao, to subdue ; stomachie quality of the plant.) D. C. 
syst. 2. p. 188. prod. 1. p. 137. Petals white, larger than the 
calyx. Siliques nearly cylindrical. Glands 4, at the base of the 
stamens. Seeds reticulately-wrinkled. Cotyledons obliquely in- 
cumbent. Perhaps a proper genus. 
1 N. orrictna‘re (B. Br. in hort. kew. ed. 2. vol. 4. p. 110.) 
leaves pinnate ; leaflets ovate , somewhat cordate, repand ; up- 
per leaves pinnatifid, with narrow segments; terminal leaflets 
large. Y. H. W. Native in rivulets throughout the world ; 
plentiful in Britain in cleat spring rivulets and ponds. Sisým- 
brium Nasturtium, Lin. spec. 917. FI. dan. t. 690. Smith. eng. 
bot. t. 855. Curt. fl. lond. 6. t. 44. Woody. med. bot. 1. p.

varieties of this plant but they are of little consequence. 
Water-cress is well known for its agreeable warmth and 
flavour, in the form of a salad, it is esteemed a wholesome sto- 
machic, and is recommended by many physicians as an antiscor-
