I. Edge of Strine's Wood, Cromford, Bailey ! The 

 Glyceria which is so common in the lower reaches of Dove 

 Dale is this variety, Purchas, J. B. 



Respecting this species Mr. Purchas writes thus: "There 

 are two forms of G. plicata ; one, which I suppose to be the 

 typical plant of Fries, is glaucous, with broad, blunt leaves, 

 which are folded in vernation ; the other, a much taller plant, 

 quite green, like G. fluitans, and with narrow-pointed, simply- 

 folded leaves, and with a much larger panicle ; both of these, 

 as well as G. pedicillata, were observed by Mr. C. Bailey and 

 myself about the upper reservoirs of the Via Gellia. These 

 forms seem to have received little notice from botanists, but 

 their differences are obvious if a little attention is given to 

 them. Of G. pediciUata the fruit seems invariably abortive, 

 if not infested with ergot, to which it is peculiarly liable. 

 I observe that Mr. Townsend in his original description gives 

 no account of the caryopsis, probably never having seen it."
