other counties, is always yellow, grows in De- 

 vonshire, and in Wales, with cream-coloured, 

 white, or red blossoms. Linnaeus observed of 

 this plant, that in (Eland, where the soil is a 

 red calcareous clay, the flowers are red ; but 

 that on the white chalky soil of Gothland, they 

 are white. 



From every hedge we may now gather the 

 flower called treacle mustard, {Erysimum alli- 

 aria.) It grows to the height of two or three 

 feet, has small white flowers of the shape 

 termed by botanists, cruciferous, and forming 

 a cross, like those of the wallflower. The 

 leaves are as large as those of the nettle ; and, 

 when broken, yield a most powerful odour of 

 garlic, which renders the plant very off'ensive 

 in a nosegay, and which even scent the dried 

 specimens in an herbarium. It was formerly 

 cultivated in kitchen gardens, as a salad plant. 



A large number of yellow cruciferous flowers^ 

 as the wild cabbage, or coleseed, (Brassica 

 napus,) the common turnip, (Brassica raj)a,) 

 and the various kinds of mustard, now show 

 themselves among the young spires of the green 

 corn-field ; and in neglected fields, threaten de- 

 struction to the blade. The charlock, or wild 

 mustard, {Sinapis arvensis,) is, too, common on 

 the cultured land, and gives much trouble to 

 the farmer. Its seeds are pungent and acrid ; 

 and are often mixed with those of the species 

 cultivated especially for mustard. It is called 

 in the diff'erent counties, charlock, garlock, or 

 chadlockj and in Yorkshire is commonly known
