VARIETIES. 



mountainous plants usually have their upper leaves more divided, 

 and their lower ones more entire, as in Pimpinella,...Petroseli? 

 NUM,...ANisuM,...and Coriandrum. 



Varieties may generally be explained and reduced under their 

 proper species with ease, by conferring the variable marks of the 

 variety with the natural plant : but there are some few which are 

 attended with difficulty, and require judgement and experience ; 



as in Some Species of HELLEEORUS*,...GENTlANAt,...FuMARIAt,... 



Valeriana §,...Scorpiurus .and Medicago^J. In respect to 

 the Fumaria in question, it is known to be one species only, by 

 the minuteness of its perianthium, the scale of its bud, the struc- 

 ture of its leaves, the situation of the branch, the place of the 

 bractea, the corolla, siliqua, seeds, and stigma ; but it varies in 

 the division of its bractea, and in the root being more or less 

 hollow : and that the Valerians here spoken of are all of tjie 

 same species, though they differ so greatly in the fruit, and of-
