associated the Catsworth plant to a group which occurs in Rhenish 

 Bavaria, and which he has named provisionally R. tomentella, Lem., 

 var. anonyma. From Dr Dingier I have received a fine series of var. 

 anomyma. There are very considerable differences amongst the different 

 specimens, especially as to the form of the leaves, but in spite of these 

 differences I am disposed to agree with him in considering them as 

 one group. One or two of his forms approach pretty closely the 

 British forms above mentioned, and perhaps until the whole group 

 has been further studied in both countries, and the results compared, 

 we may call ours also in the meantime R. Borreri, Woods, var. anonyma.^' 

 — W. Barclay. "This seems to be an extreme form of the plant 

 referred to under R. Beatricis, Burn, and Geml., on p. 21 of my List of 

 British Roses. I believe Prof. Dingier suggested some other name for 

 it, but I am writing away from my herbarium and notes, so have only 

 my memory to guide me. These specimens have many of their leaflets 

 as glandular beneath as in the Micranthae, with which the Scahratae 

 form a connecting link, but the aciculate flowering branches are 

 unusual for either sub-group, though similar ones are occasionally found 

 in otherwise very different specimens. I can give no definite name to 

 Mr Bi'itton's plant." — A. H. W.-Dod. " Near the Coombe plant ; 

 fruits not so round, but they appear scarcely separable." — E. S. 

 Marshall. " No flowers. I think both these come under my Rosa 

 Rothschildii (see Report 1912, pp. 157-159), notwithstanding their 

 more spherical fruit, and slightly more hairy mid-rib." — G. C. Druce. 



Rosa involuta, Sm. forma = Rosa pimpifielli/olia x tomentosa. 

 June 24, Aug. 1, Oct. 1, 1912. In each sheet I enclose a specimen 

 grown in a garden for fifteen years and one in the wild state about 

 50 ft. higher up. The wild one seldom blooms, being in a shady spot, 

 and it is gradually dwindling and dying out. The flower is larger 

 and solitary, not a cluster, as it is under cultivation, where the plant 

 becomes a large and beautiful bush. — I. M. Hayward. "I have 

 seen a number of specimens of Miss Hay ward's rose, received from 

 hei'self, and consider it as the hybrid R. pimpinellifolia x tomentosa 

 ( omissa group). The omissa group is the prevailing form of tomentosa 

 in Selkirk. The leaves of the Selkirk hybrid are much less hairy 

 than in most Scottish forms of the same rose." — W. Barclay. 

 " Yes, a form of this hybrid with thinly hairy leaflets, which, for 

 those who prefer a segregate name, may be placed under R. Sabini, 

 Woods." — A. H. W.-DoD. " Upon the whole, I am disposed to think 

 this R. mollis x spinosissima, though the pedicels are rather long for 

 that hybrid." — E. S. Marshall. 



Rosa mollis x spinosissima ( R. Sahini, Woods). Near Roley 

 Bridge, Westmorland, Aug. 7, 1912. Though I have labelled these 

 specimens as above, I do not mean it to be inferred that I think
