Alchemilla acutidens Bus., var. alpestriformis 0. E. S. Origin 

 near Lochan-na-Ohat, Ben Lawers, 1913. Hort. Reigate, Surrey, 

 Aug. 1914. See Journ. Bot. 1914, p. 287. It was noticeable how 

 much smaller these plants kept compared with A. alpestris grown 

 alongside in the garden. — C. E. Salmon. 



Bosa sempervirens L., b. Melvini (Towndrow). Edge of pond, 

 Leigh Linton, Worcester, v.-c. 37; May 7, 1914. — Coll. R. F. 

 Towndrow ; comm. C. Waterfall. " So very much off R. 

 sempervirens, as I have seen it in N. France, that I incline to think 

 it specifically distinct. Not known elsewhere, I believe." — E. S. 

 Marshall. 



Rosa canina L., agg. [Ref. No. 4951.] Han well, Oxon, Aug. 

 1910. — G. 0. Druce. Comes between (1) andegavensis Bast, and 

 (p) verticillacantha Merat ; that is, some leaflets have most or all of 

 the teeth simple, whilst others have them more or less compound. 

 According to Keller and Christ, R. hirtella Rip. is a somewhat similar 

 form, but with oval fruit and sepals glandular on back." — W. Barclay. 



Rosa dumetorum Thuill., var. platyphylla Rau. [Ref. No. 3.] 

 Hedge, Grey Abbey, Co. Down, Sept. 3, 1914. Leaves irregular 

 in size ; some very large, very dark green above. Approaching 

 biserrate towards top of leaf. Fruit single; some very large 

 and turbinate. — C. H. Waddell. " This is a form of R. 

 dumetorum Thuill. The (g) platyphylla Rau., so far as I can 

 make out, differs from (d) urbica chiefly by having leaflets 

 broader in proportion to their length. The present specimen 

 does not show this difference. It had best be set down as a glaucous 

 form of (d) urbica, with globose instead of ovoid fruit." — W. Barclay. 

 " I do not think this can be R. platyphylla Rau., which, according to 

 descriptions, is a plant with much broader leaflets — orbicular or very 

 broadly oval — and fruit tending to a more ovoid form. I should call 

 this R. sphaerocarpa Pug." — C. E. Britton. 



Rosa glauca Yill. [Ref. No. 1]. Grey Abbey, Co. Down, Septem- 

 ber 3, 1914. — C. H. Waddell. "Not materially different from No. 

 2. Serration rather moi-e compound. Both are glaucous forms, and 

 might therefore, according to Baker, come under var. glaucophylln, 

 Winch." — W. Barclay. "Fruit subglobose; sepals deciduous, patent 

 or loosely reflexed ; leaflets slightly compound-serrate. It can hardly 

 be any form of R. glauca. Is it not a ' canina ' (aggregate), of the 8. 

 sphaerica Gren., or R. globularis Franchet aflinity T — E. S. Marshall. 



Rosa glauca Vill. [Ref. No. 2]. Grey Abbey, Co. Down, Septem- 

 ber 3, 1914. — C. H. Waddell. "This is not a form of R. glauca but 

 R. ca7iina L. (g) dumalis Bechst." — W. Barclay.
