300 On the Woburn Perennial Kale. 



to four inches apart, to be afterwards transplanted when 

 well rooted, to where they are intended to remain. The 

 cuttings should be inserted into the ground three parts of 

 their length. A soil intermediate as to moisture and dryness 

 suits them best. Like most of the Brassicae, this Kale re- 

 quires a rich soil, particularly for the first season ; it thrives 

 however on clays, as well as on sandy soils, but the weight 

 of produce on such, is proportionably less. 



From defective structure in the essential parts of its 

 blossoms, this Perennial Kale perfects little seed ; but as it 

 propagates so freely by cuttings, the want of seed is scarcely 

 felt in its culture ; and indeed as it is subject to sport much 

 when raised from seed, it seems essential to the preserva- 

 tion of the particular variety, that it should be increased by 

 cuttings. 



Having obtained about two ounces of the seed from 

 plants, grown in a situation remote from any other cabbage, 

 and even from any cruciferous plant, it was sown. The 

 plants raised from it have exhibited ten distinct varieties, 

 they are now three years old ; of these, there is only one 

 that perfectly agrees in all points with the parent stock ; 

 the rest are different in the colour and form of the leaves. 

 Specimens of the leaves of these have been prepared, and 

 sent for the inspection of the Horticultural Society. The 

 plant which is farthest removed from the original, has the 

 leaves smooth, fleshy, nearly entire, and in colour and sub- 

 stance precisely resembling the young leaves, or those emitted 

 by the stems, of the Early York and Imperial Cabbages ; from 

 this, through nine others, the, colour, form, incisions, and
