SECTION III. 



Of the different Gi^asses, and other Plants, which are natural to 

 J)ry, Sandy, and Elevated Soils. 



The former class of grasses was distinguished by their superior 

 size, the greater succulency of every part of their structure, and 

 by their broad green leaves — all indicating the fertile nature and 

 sheltered situation of the soil that produces them ; and the fol- 

 lowing grasses are distinguished from these, by their dwarfish 

 size, and the wiry appearance of every part of their structure, 

 which sufficiently denote the poverty of their natural soil.

 the head of grasses natural to wet soils), tufted-leaved bent

 flat-stalked meadow-grass {Poa compressa), upright flat-stalked 

 meadow-grass {Poa compressa, var. erecta), meadow-barley* {Hor- 

 deum pratense), bird's-foot clover {Lotus corniculatus), larger bird's- 

 foot clover* {Lotus major), trefoil, or nonsuch {Medicago lupulina) ; 

 to which may be added, Hedysarum onohrychis (sainfoin). The 

 following, belonging to this class of grasses, have already been 

 brought under observation: — Soft brome-grass (Bromus mollis), 



* Frequent on dry banks where the subsoil is a wet clay.
