EXTKACTS FROM REPORT OF BOTANICAL EXCHANGE CLUB, 1887. 53 



obifcurum, Galium elongatum, Valeriana Mikanii, Arcticiim nemorosum, 

 Veronica Buxhaumii, Atriplex erecta, Potamogeton natans, and Spar- 

 ganium neglectum. — Charles Bailey. 



R. nemoralis Muell. [R. Muenteri Marss.), fide 0. C. Babington. 

 Quakers' Wood, near York. Petals white, stamens and pistils white. 

 August, 1887. Professor Babington says of this, that it is what he 

 should have called a state of his " macrophyllus, glabratus,'' but 

 thinks it is as above. — Geo. Webster. "Group of rhaumifolius, 

 near R. cardiophyllus Lefv. & Muell." — W. 0. Focke. "Is most 

 certainly the old umbrosus of Babington, and carpinifolixis of Bloxam. 

 It is a Bramble I know well, as it occurs about Plymouth in two 

 forms, the larger well represented by Mr. Webster's specimens, 

 being found in many places in the enclosed country ; and a smaller 

 form growing on the downs, or wider and more open places. I 

 suppose these w^ould now be placed by Babington under Maassii or 

 Muenteri. The terminal leaflet of Mr. Webster's plant seems most 

 like that of Muenteri, as described by Babington in Journ. Bot. for 

 last year, p. 333."— T. E. A. Briggs. 



R. melanoxylon Miill. & Wirtg. Branksome, Dorset; rough 

 bushy ground," in good quantity, 29th July, 1887. This is the 

 plant described by Prof. Babington in Journ. Bot. 1887, pp. 21, 22. 

 I have found it this year in several widely- separated localities near 

 East Dorset, and also near Brockenhurst, in the New Forest,_ S. 

 Hants. It will be of interest to several members of the Club if I 

 add that the R. plinthostyhis described by the Professor in the same 

 paper (p. 22) is the beautiful little bramble which I sent for 

 distribution as a small Koehleri form from Minster Valley, E. Corn- 

 wall, in 1885. — W. Moyle Kogers. New records for Vice-counties 

 9 and 11. 



R. chlorothyrsus Focke. Shirley, Derbyshire, September, 1887. 

 Only observed in one lane. I shall be glad to learn whether this is 

 agreed to as the true chlorothyrsus, as it differs from specimens 

 bearing the same name which I have received from the Continent. — 

 W. R. Linton, "i?. chlorothyrsus Focke, or very near to it." — 

 W. 0. Focke. First record for Britain. 



R. gratus Focke. Shirley, Derbyshire, July, 1887. Only a single 

 bush has been observed, occurring in a swampy and open part of 

 Shirley Wood, among bushes of Pi. carpinifolius W. & N. and 

 R.fissus Lindl.— W. R. Linton. Mousehold Heath, Norfolk, 22nd 

 August and 30th September, 1887.— E. F. Linton. So named by 

 Dr. Focke. New county record. 



R. Maassii Focke = R. umbrosus (Bab. Man.). Ansley, War- 

 wickshire, 20th August, 1887. As this is one of the commonest 

 British brambles, I have only sent a limited supply, assuming that 

 it is only required as a voucher for correctness in nomenclature. — 

 J. E. Bagnall. This plant, Mr. Baker thinks, should be called 

 R. polyanthemos Lindeb. It is undoubtedly the umbrosus Bab., 

 carpinifolius Blox., and R. Maassii Lond. Cat., but differs totally 

 from specimens named R. Maassii for Mr. Baker by Dr. Focke, 

 which is the R. cordifolius of English authors. — G. N. 



R. Maassii Focke. St. Paul's Cray Common, Kent , 1887.—
