I should like to see more and better specimens, but I expect it is forma 

 triloba, unless it be a hybrid with oxyacanthoidesT — G. C. Druce. 



CratcBgus punctata Jacq. Planted ground, Dalton-in-Furness, 

 v.-c. 69b, June 15, 1914. — D. Lumb. " In the absence of fruit it is 

 not possible to name this definitely. In any case, being a cultivated 

 tree, it is of no interest to the members." — A. B. Jackson. "Yes, 

 similar to the plants so named by Dr Thellung."' — G. C. Druce. 



Saxifraga aizoides L. Mountain streamlet above Easedale Tarn, 

 Westmoreland, v.-c. 69, July 19, 1914. — C. Waterfall. 



Saxifraga hypnoides L., agg. [Ref. No. 2902.] Ben Bulben, 

 Sligo, June 1909. — G. C. Druce. "Yes, and under the type, I should 

 say." — E. S. Marshall. 



Saxifraga stellaris L. Swamps on descent of Red Screes towards 

 Scandale Beck, near Ambleside, Westmoreland, v.-c. 69, July 29, 

 1914. — C. Waterfall. 



Saxifraga hirsuta L., var. acutidens E. S. Marshall. [Ref. No. 

 3647.] Roots from cliffs above Lough Doon, Connor Hill, S. Kerry, 

 June 1911; flower garden. West Monkton, May 24, 1914. The 

 Linnean type has crenate leaf -toothing ; in var. acutidens it is serrate. 

 This is the usual Irish form, and varying considerably in the shape of 

 the lamina, and in the amount of hairiness. The leaf-bases are trun- 

 cate or somewhat cuneate ; I believe that a cordate base indicates 

 crossing with S. Geum. — E. S. Marshall. 



Chrysosplenium alter nifoliura L. Wet places. Via Gelia, Derby- 

 shire, v.-c. 57, April 12, 1914. Intermixed with oppositifolium. —

Sedium Forsterianum Sm., type (Watson's a. virescens). [Ref. No. 

 4034.] Root from Culbone Woods, S. Somet-set, v.-c. 5. After several 

 years' cultivation its green foliage is maintained ; and it is less robust 

 than the var. glaucescens, from the coast near Minehead ; garden. 

 West Monkton, June 24, 1914. — E. S. Marshall. 



Callitriche ohtusangula Le Gall. Pools on Upper Chase Road, 

 Malvern, Worcester, v.-c. 37, May 13,1914. — C. Waterfall, "I 

 am unable to pass an opinion on such specimens." — A. Bennett. 

 " Neither habit nor fruit suggest this, to me ; the latter is flat, not 

 obtusely angled. I think it a form of G. stagnalis Scop., but more
