Ruhus le7itiginosus, Lees. [Ref. No. 343.] Rocky ground at Capel 

 Curig, among low bushes on the ascent to Moel Siabod, v.-c. 49, 

 July 11, 1912. On specimens submitted to Rev. Moyle Rogers, he 

 wrote : ' Good R. letdiginosus, Lees, practically identical with Lees' 

 small specimen of it from Aber Valley, now in my herbarium. I 

 should not be surprised if it is identical with Lees' type specimen 

 now in the Herh. Bah. at Cambridge, collected by him on the rocky 

 ground at Capel Curig among low bushes on the ascent to Moel 

 Siabod, Aug. 1849.'— S. H. Bickham. " Correct."— W. M. Rogers.

Potentilla mixta, Nolte (P. reptans x procumhens). Peat moor, 

 Ashcot Road, North Somerset, Aug. 6, 1912. — J. W. White. "Looks
