TO BOTANY. 173 



it is observed, that watery soils are apt to produce a 

 division in the lower leaves of the plant, and even 

 to render capillary such as are produced under the 

 water; as in some species of Ranunculus and Sisyrn- 

 brium*; and also in Cicuta, Sium, Phellandriutn, 

 Oenanthc, &c. And on the contrary, that mon- 

 taneous plants usually have their upper leaves more 

 divided, their lower ones more entire^ as in Pini- 

 pinella, Petroseiinum, 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 judgment and experi- 

 ence, as in some species of Helleborus'f GehtianaJ,
