34() 8YNGENESIA— POLYGAM1A-.12QU. Lactuca. 



Respect for Ray and Gerarde may lead us to suppose our f3 differs 

 in some degree from the plant in its ordinary state, with which 

 Ray says it is found, though rarely. Its scent is reported to be 

 milder. Gerarde cites the above synonyms of Tragus and Dale- 

 champ for this variety ; but neither their figures, nor Petiver's 

 f. 1 , indicate any thing but the most common appearance of the 

 leaves, which are liable, on the same plant, to be wavy or 

 slightly lobed 5 a difference which cannot be attended with any 

 change of quality. Ray, and Dillenius who merely copies him, 

 mention this variety as if it belonged to L. Scaiiola ; but Gerarde 

 certainly takes it for L. virosa. C. Bauhin confounds some of 

 its synonyms with the following.
