SHORT NOTES. 



Alchemilla acutidens Buser in Britain. — During the Inter- 

 national Phy to-Geographical Excursion in August of 1911, Dr. 

 Ostenfeld pointed out this plant on Ben Lawers, first on a rock by 

 the Carrie burn, at about 1200 ft., and also in several other places 

 on the hill up to 3500 ft., and also on rocks above Lochan a Chat. 

 It is kept as a distinct species by H. Lindberg {Die novel Alchimilla- 

 vulgaris Forinen, p. Ill, t. 16, 1909), but is closely related to 

 Alchemilla alpestris, with which, indeed, it has been sometimes 

 confounded in Britain. My specimens from Nant Francon, Car- 

 narvonshire, collected in 1899, are, according to Dr. Ostenfeld, 

 not alpestris but acutidens, and to this also belong Mr. McTaggart's 

 Linlithgow specimens, distributed through the Botanical Exchange 

 Club in 1910 ; specimens collected by the Eev. E. S. Marshall at 

 Inchory, Banff, in 1905, are said by Dr. Moss to be the same form. 

 My specimens of A. alpestris from Middlesex are correctly named. 

 Lindberg thus describes the two plants ( opi. cit. p. 42) : — 



A. acutidens Buser. — " Caules usque ad ramulum floriferum 

 secundum vel raro tertium et petioli + pilosi, folia subtus nervis 

 per totam longitudinem + pilosis. Inflorescentia lata, multiflora, 

 densa, subcorymbosa, stipulia profunde incisa, folia viridia, orbicu- 

 laria vel reniformia, 9- vel rarius incomplete 11-loba, supra glabra 

 vel rarius in plicis pauci-pilosa, lobi dentibus conformibus, utrim- 

 que (7) 8-9 (10), acutis vel acutiusculis, dens apicalis vicinis asqui- 

 longus et conformis, raro paullo brevier, flores subvirides, sepala 

 et episepala angustioria et acutioria." 



A. alpestris Schmidt. — " Caules tantum in internodio primo 

 ± dense et in internodio secundo + parce pilosi, fere numquam 

 usque ad ramulum floriferum infimum pilosi, petioli + parce 

 pilosi vel subglabri, omnino glabri, folia magna, reniformia, dilute 

 viridia, 9- vel raro incomplete 11-loba, supra glaberrima (tantum 

 in dentibus breviter pilosiuscula) vel rarissime in plicis paucis 

 munita, subtus tantum secus apices nervorum adpresse pilosa, 

 lobi dentibus utrimque (6) 7-9 (10), dentes inaequales, dens apicahs 

 parvus, vicinis multo minor, inflorescentia vulgo satis angusta, 

 flores vulgo flavo-virentes." — G. C. Deuce. 



Equisetum hyemale Linn, in Hants. — Specimens of Equi- 

 setum hyemale L. were sent me in February by Mr. J. F. Eayner, 

 who, in company wdth Miss Mabel Moore, found a large quantity 

 of it, apparently quite native, in a peninsula of damp clay ground 

 formed by the winding of Tanner's Brook, in Lord's Wood, four 

 miles from Southampton. The spot, Mr. Eayner tells me, is in 

 district vii (2), not far from the boundary of vi (2), of the Flora 

 of Hants. In the southern counties it is only known for Somer- 

 set N. (one locality), for Surrey, and for Kent E., one locahty, 

 recorded in Phytol. v. 45 (1853), by W. Borrer, on specimens from 

 the Eev. G. E. Smith, a locahty w^hich the authors of the Flora of 

 Kent were not able to trace. Mr. Eayner in answer to a question 

 rephed, " I never heard of any plant being introduced in this 

 wood, and I think we may safely dismiss the idea" of its intro- 

 duction. — E. F. Linton.
