21. 6 — 9. — S'^ems 



3 feet high. 



If any leaves grow under water, they are deeply pinna 

 tifid, otherwise only deeply serrate. Pedicels usually deflexed. Style 

 as long as the oblong germen. A. natans {Nasturtium DC.) is closely 

 allied ; so also is A, Americana (Nasturtium natans Torr. and Gr.), 

 but it has the white petals and peltate stigma of the next. 



2. A. ^rusticdna Baumg. (common H.) ; ra< 

 on lono- fdot-stalks crenate, cauline ones elongato-lanceolate 

 serrate'^or entire, root long cylindrical, petals (white) twice as 

 lon^^" as the calyx, pouch 2 — 3 times shorter than the pedicel, 

 stifona peltate. Cochlearia Armoracia X.; E. B. t. 2323. 



Said to be wild near Swansea ; also in some parts of the north of 

 En"-land,'and in Scotland, but too often the outcast of gardens. %. 



5. Eoots long, running deep into the ground, well known at our 



tables, and esteemed for their pungent flavour. Leaves much veined. 

 Fruit seldom perfect.

a and y on the sea-coast, in a stony or muddy soil, frequent ; P on 

 the Highland mountains. or %. 5_8.— The common variety 

 exhibits, on the shores of the Frith of Clyde, all the variations noticed 

 in the shape of the pouch, which is, moreover, often as large and 

 veiny as in the figure of C. Anglica, in E. B. t. 5.52. The true 

 radical leaves of our var. y are perhaps always reniform ; but having 

 decayed, or been broken off, the lower cauline ones are mistaken for 

 them. 



2. C. 



. A'nglica L. (English S.) ; pouch elliptical (large) 

 veiny, radical leaves petiolate ovate or oblong entire mostly 

 acute or tapering at the base sometimes subcordate, cauline 

 leaves mostly sessile oblong sinuate or with a few coarse teeth. 

 E. B. t. 552. 



Margins of large rivers, at a distance from the open sea, perhaps 

 not uncommon. Thames between London and Woolwich; Avon 

 above Bristol; Mersey near Warrington. Cree near Newton Ste-
