In groves in the south of England, but rare. 



In a wood to the west of Tring, Hertfordshire, certainly wild, first 

 noticed, I believe, by the late Mr. Dickson. In Charlton forest, 

 Sussex. Mr. Borrcr. 



Perennial. June — September. 



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

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

 considerably deflexed, hairs of all the Jlower-slallcs, 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, 

 wl)ich Linnceus confounded, by analogous marks. The powers 

 of F. elatior are generally, but not always, imperfectly dioecious j 

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

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

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

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

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

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



F, sterilis of Linnaeus and Fl. Brit, is removed to the next genus.

Cal. inferior, of 1 leaf, flattish, permanent; limb in 10 deep 

 segments, 5 alternate ones external, and narrowest. Pet. 

 5, roundish, or heart-shaped, spreading, opposite to the 

 external segments of the calyx, and attached by their 

 short claws to its rim. Filam. about 20, from the rim of 

 the calyx, awl-shaped, erect, shorter than the corolla. 

 Antli. roundish, incumbent, of 2 cells. Germ, superior, 

 numerous, roundish, small, collected into a round head. 

 Styles thread-shaped, 1 to each germen, lateral, ascending, 

 permanent. Stigmas bluntish, downy. Seeds numerous, 

 naked, roundish, generally more or less wrinkled, cover- 

 ing the surface of a small, dry, globular, permanent, un- 

 altered receptacle, to which each is laterally attached, 

 below the insertion of its style. 



Mostly perennial ; rarely shrubby. Leaves alternate ; pin- 

 nate, digitate, or ternate ; for the most part deeply ser-
