There are varieties with white flowers and with wrinkled leaves. 

 The fourth species seldom rise more than nine, commonly from 

 four to six inches high, in its native situation, and when transplanted 

 into gardens, from nine to ten, but rarely above sixteen. At the 

 top of each stalk is one large blue flower, somewhat like that of 

 the Italian Starwort. It flowers in June, and is a native of the 

 Alps, &c. 



There are varieties with white rays and with blue rays. 

 The fifth species has many stems, five feet high, brown, termi- 

 nated by large purple violet flowers, growing in a loose panicle, and 

 expanding in August. The peduncles are so short as scarcely to 

 appear among the flowers. It is a native of New England. 



The sixth has many stems, three and even four feet high, stiff", 

 reddish, hairy, and branching pyramid ically. The branches have 

 small lanceolate leaves, growing alternate, hairy and rough to the 

 touch, the size of those of common Hyssop, and each terminated by 

 one large blue flower, coming out at the end of October. It is a 

 native of Virginia. 



The seventh sort has several strong stems, upwards of two feet 

 high, of a purple colour; but the flowers are on single peduncles, 

 forming a corymb at top, and of a pale blue colour: they appear 

 about the end of September. It is a native of North America; va- 

 ries in height from eight to three feet, having the stems either dark 

 purple or reddish green. 



There is a variety, in which the flowers are purple inclining to 

 red, and surrounded by a few narrow leaves. This is from Phila- 

 delphia, and flowers in November. 



The eighth species has the leaves broad and heart-shaped at 

 bottom ; the stems between two and three feet high, with small side 

 branches, upon which the flowers come out in loose spikes; they are 

 of a pale blue colour, inclining to white. It flowers in August. It 

 is a native of North America. 



The ninth has the leaves lanceolate, gradually narrowing to the 

 end: peduncles with very small subulate scales: the stems strong ? 

 from two to three feet high, putting out many side branches near half
