Juncus filiformis still grows plentifully in a meadow between the 

 town and the lake at Keswick. Asarum europaeum is found in small 

 quantities in Troutbeck. Meum athamanticum, scarce near Keswick ; 

 Hieracium aurantiacum, vale of Newlands ; Euphorbia Cyparissias, 

 in Ulpha ; Meconopsis cambrica and Spiraea salicifolia between 

 Hawkshead and the Ferry ; Lobelia Dortraanna grows in most of the 

 lakes ; Atropa Belladonna at Furness Abbey apd Arnside Tower, 

 Also Pyrola secunda, Listera Nidus-avis and Oxyria reniformis, near 

 Keswick. 



Specimens of all the plants above enumerated were shown to me, 

 from their respective localities, except Cypripedium. 



Before concluding, I may just say, that Galium Vaillantii has reap- 

 peared in this neighbourhood, and in several situations where it was 

 not noticed last year, so that I cannot doubt that it will be found in 

 other places, having been mistaken for G. Aparine, from which I 

 believe it is now generally allowed to be distinct. The differences 

 between the two plants, as pointed out in a former communication, 

 are clear, and proved to be permanent by cultivation, which only 

 renders them more striking. I shall be glad to supply any botanical 

 friends with a specimen of this interesting addition to our British 

 Flora, as far as my stock will allow, and doubt not that another sea- 

 son any deficiency can be made up. I hope, too, that throughout 

 the country botanists will search for it, and quite expect they will be 

 rewarded by the discovery of it in many other places.

Remarks on Mr. Watson's Report of an Experiment which bears on 

 the specific identity of the Cowslip and Primrose, (Phytol. ii. 

 217). By Edward S. Wilson, Esq. 



As no one else seems inclined to take up the subject of Mr. Wat- 

 son's experiment, I venture to suggest an explanation, which, though 

 merely hypothetical, may possibly prove to be the true one. 



It appears to me that the whole question may be resolved into these 

 two : — 



1. — Does the vegetable hybrid possess the power of reproduction ? 



2. — If so, was the plant of which the seeds were sown by Mr. 

 Watson, a hybrid ?
