flower from the early Spring till late in Summer. It is neither 

 handsome nor useful ; its flowers are extremely small, occupy- 

 ing all the upper part of the stem and branches, opening first 

 in the lower part, and gradually proceeding upwards, until 

 very soon flowers may be seen coming out at the top of the 

 stem, and the heart-shaped seed vessels opening and scattering 

 the ripe seeds below. The leaves are alternate, those on the 

 stem sessile, with two long projections, where they join the 

 stem. The root leaves winged to their base, and growing 

 round in a circle, close to the ground. Their shape is very 

 various, sometimes not at all divided, at other times deeply 

 cleft, and generally the drier the place where the plants grow 

 the more deeply divided they are. 



SCURVY-GRASS. COCHLEARIA. 



HORSE-RADISH. Cocklearia armoracia. 



Plate 9, fiy. 18. 



The Horse-radish will grow even from a small bit of the root 

 being put or left in the ground, and is cultivated in almost 

 every garden on account of its pungent flavor, and therefore 

 whether a native plant or not, it is now found frequently on 

 dunghills, on river-banks, and about the fields ; being, when 

 in flower, which is in July and August, of the height of three 

 or four feet, with very numerous branches of small white 

 flowers, which produce oblong, roundish, many-seeded pods. 

 The root-leaves are often two feet long, coarse in look, of a 

 dark green, much veined, serrated, and upon long stalks, while 

 the other leaves taper gradually down the stem. Many acres 

 of the Horse-radish are grown in every direction around 

 London for the markets.
