Centrantluxs Calcitrapa is at your service, if you think it worth insert- 

 ing among your Varieties. It is now fifty, if not sixty, years since I 

 first saw this plant on a wall at Elthara, where it was well known to 

 the London botanists, who, I believe, always thought it had es- 

 caped from Sherard's garden, and it was therefore considered a natu- 

 ralized plant, not to be admitted into a British Flora. We also used, 

 at the same time, to find it on the wall of a garden at Enfield, in Mid- 

 dlesex, which had formerly been that of Dr. Uvedale, the friend of 

 Plukenet, in which was then a celebrated cedar of Lebanon. Not 

 having been that way lately, I do not know the present state of the 

 place. — Edwd. Forster ; Woodford, June 6, 1843. 



329. Note o?i Myosotis sylvatica. I find Myosotis sylvatica grow- 

 ing abundantly in several ash plantations in this neighbourhood. It 

 flowers throughout the month of May and the early part of June, and 

 during this period makes a very splendid appearance. T have recent- 

 ly observed a beautiful variety with pure white flowers, which I think 

 is not common ; a specimen of it I now enclose, — Thomas Bentall ; 

 Hahtead, Essex, June 7, 1843. 



330. Note on Equisetum Jluviatile, Sm. It is highly desirable that 

 the controversy respecting Equisetum fluviatile should be settled as 

 early as possible, and surely there can be no great difliculty in the 

 matter. About Manchester it is one of our very common plants, grow- 

 ing in woods, pastures, meadows, and moist gravelly banks, but I ne- 

 ver yet met with it growing in water. The nearest approach to the 

 latter habitat is in the wood below Arden Hall, Cheshire, where it 

 flourishes in a sicamp, to the height of six or seven feet. Now the 

 branched state of E. limosum, which is not unlike fluviatile in gene- 

 ral appearance, completely fills up many of the ponds in this neigh- 

 bourhood, and I am therefore induced to think it possible that the two 

 plants may sometimes have been confounded, and that thus the ques- 

 tion as to the true habitat of E. fluviatile has originated. At Reddish, 

 yesterday, I noticed a cow in one of the limosum ponds, eating ofi' 

 the tops of this species ; but whether from a liking to the Equisetum, 

 or to the Glyceria fluitans which was growing with it, I am unable to 

 say. — Joseph Sidehotham ; Manchester, June 9, 1843. 



331. Note on Fragaria elatior. I am almost inclined to believe 

 that the authors of the various works on the British Flora, must have 

 written their descriptions of Fragaria vesca and elatior, without hav- 

 ing seen specimens of the latter. According to Sir W. J. Hooker, 

 the hairs of the pedicels are closely pressed in F. vesca, but widely 

 spreading in elatior ; this is the only character given by which we are
