A gay little plant, forming one more addition to the large 

 genus Lupinus. The flowers are rich bright lilac, enlivened 

 by a yellow spot on the white centre of the vexillum. In 

 number the leaflets vary from 5 to 9. The seeds, by which 

 Lupines may be distinguished more accurately than by the 

 ordinary marks employed by Botanists, are oblong, smooth, 

 and mottled with grey of different tints. Fig. 3, represents 

 one of them ; 2, is a ripe pod ; and 1, is the ovary and style. 



It is a half hardy biennial, growing from one to two feet 

 high, and flowering a great part of the summer and autumn. 

 Like other Lupines it requires a strong rich soil, and although 

 a half shrubby biennial, is best treated as an annual. 



The seeds should be sown about the beginning of March, 

 in pans filled with a loamy soil, and when large enough should 

 be potted, placing three plants in a small pot ; afterwards, 

 when the danger of the late spring frosts is over, they may be 

 planted out in the open border. The seeds may also be sown 

 in the open border about the middle of April, but then the 



January, 1844. b
