THE FLORA OF WENSLEYDALE: 

 ADDITIONS AND CORRECTIONS. 



JOHN PERCIVAL, B.A. 



I FIND that there are several omissions from my paper on Wensley- 

 dale plants in The Naturalist for Alay ; and I take the opportunity of 

 making an obvious correction. 



[Ceterach officinarum Willd. ' Wall in Mr. Willan's [wood] yard 

 at Appersett, Moore' (Baker's North Yorkshire). Gone. Sought 

 for without success by Wheldon about i860, and by Lees 

 1884-6. The old wall still nourishes Aspleniuni triclioinanes 

 and A. ruta-imiraria (F. A. Lees)]. 



Nephrodium dilatatum var. alpina Moore. In peat-holes on 

 Dod Fell summit, at 2,100 ft. (A. Crosfield and F. A. Lees). 



Ophioglossum vulgatum L. 



Botrychium lunaria Sw. Common in the pastures throughout 

 the dale. 



Lycopodium selago L. 



Lycopodium clavatum L. Grit-heathery summit of Wether 

 Fell; and Lovely Seat (F. A. Lees). 



Selaginella selaginoides Gray. 

 Equisetum arvense L., and E. maximum Lam. 

 Equisetum sylvaticum L., and E. palustre L. 

 Equisetum limosum L. In Locker Tarn, Carperby. 

 Nitella opaca Ag. In the Yore near Bear Park, Carperby; and 

 in Bishopdale Beck near Thoralby. 



Chara foetida Br. 



Chara hispida L. In Locker Tarn, Carperby. 



Chara aspera AMlld. In pool near Yore Mills; and in the Yore 



near the Aysgarth ford. 

 Chara fragilis Desv. In the Yore at Hawes. 

 Chara contraria A. Br. In pool near Yore at Aysgarth Waterfalls. 



Erratum. — In former list (p. 141), the Var. flavescens Moore, 

 of Sesleria caerulea, is misreferred to the i)recedmg species 

 (Phleum). 



June 1888.
