23. LEGUMINOSiE. 



Range of mean annual temperature 51 — 40. 



Native. Sylvestral. Very frequent in the agrarian re- 

 gion ; becoming scarce above 400 or 500 yards. Being 

 omitted from the Flora of Shetland, the county census is 

 accordingly brought one step under the highest number ; 

 those isles being reckoned as one county.

Native. Rupestral, &c. Although recorded from few 

 localities only, the situations of grovrth are so variously 

 described that it is uncertain which of the series of terms 

 will best express the usual haunts of this species. Having 

 myself seen it only on the cliffs of the coast, and finding 

 the like situations indicated for it by some other botanists, 

 the term ' rupestral ' is adopted, although not very charac- 

 teristic. It is said to grow in the counties of Devon, 

 Somerset, Dorset, Hants, Sussex (now extinct?), Kent, 

 Essex, Gloucester, Worcester, Glamorgan, Denbigh, Flint 

 and York; the two latter resting on old authority, the 

 confirmation of which would be desirable.
