 Sussex, Mr. Borrer.

Larger than the foregoing, and rather more hairy in every part. 

 The essential difference consists in the long, wide-spreading, or 

 considerably deflexed, hairs of all the Jiower-slalks, as well as 

 footstalks. This is liable to no variation or uncertainty, when 

 properly observed. Ehrhart first used it for specific discrimina- 

 tion, and has distinguished all the real species of Strawberry, 

 which Linnteus confounded, by analogous marks. The flowers 

 of F. elatior are generally, but not always, imperfectly dicecious ; 

 those on one plant having the stamens most efiectual, whilst an- 

 other bears the most complete pistils. A garden variety, noticed 

 in Rees's Cijrlopcedia, is supposed always to bear perfect flowers ; 

 but this is not generally the case with tlie cultivated plant. The 

 fruit is the true Hautboy, known by its larger size, dark hue, 

 and peculiar musky flavour. 1 have never seen it wild. 



F. sterilis of Linmeus'and FL Brit, is removed to the next genus.
