ORDER XXXVII.— BRASSICACE^, Lindl. Nat. Syst. p. 58. 



THE CABBAGE TRIBE. 



Herbs, annual, biennial, or perennial, very seldom under- shrubs. Ex- 

 clusive of species that are uncertain, or common to several different 

 countries, it appears that about 100 are found in the southern hemisphere, 

 and about 800 in the northern, and of these 9 1 in the new and the rest in 

 the old world. 



This calculation will, however, require considerable modification, esj)e- 

 cially in the Asiatic and N. American numbers, {Lindl.) and we shall, 

 perhaps, not err much, if we take the amount of species of the whole or- 

 der to be upwards of 1200. The Indian forms according to our materials, 

 are 48 : 7 of Nasturtium ; 2 of Turritis ; 2 of Arabis ; 8 of Cardamine ; 2 of 

 Pteroneuron ; 1 of Farsetia ; 6 of Draba ; 1 of Cochlearia ? 1 of Thlaspi ; 

 1 of Capsella ; 1 of Hesperis ; 1 of Sisymbrium ; 1 of Alliariu ; 1 of Le- 

 pidium ; {Roxb.) 1 of Tauscheria ; 9 of Sinapis ; 1 of Eruca ; and 1 of 

 Crambe. Fourteen of these are common to several parts of the world ; 1 6 

 have been found in the Himalayas ; 5 on the Neelgherries ; 2 in Cochin- 

 China ; 4 in Java ; 8 in Kunawar ; and 1 1 in the plains, chiefly of Bengal. 



Acrimony and bitterness form the grand characteristics of this useful 

 order, to which we owe most of our antiscorbutic herbs, and a number of our 

 Kitchen-vegetables. The principle of acridity seems to be a volatile oil, 

 that soon evaporate, and, therefore, is greatly diminished by drying. It 

 abounds in the Horse-radish, Common Cress, Radish, (especially the black 

 Spanish Radish,) &c. which renders it necessary that these should be eaten 

 fresh. In others the acrimony is mitigated by an abundance of mucilage,
