is scarcely so typical." — G. C. Druce. "Only one Forfarshire 

 specimen sent." — J. Cryer. 



Crataegus monogyna x oxyacanthoides 1 [Ref. No. 4820.] Twin- 

 stead, Essex N., May 1912. Veins recurved, styles 1 and 2, calyx 

 glabrous. — G C, Druce. " Probably right enough ; but mere scraps, 

 of little us(i for herbarium study." — E. S. Marshall. 



Cratcegus monogyna x oxyacanthoides 1 [Ref. No. 4844.] Twin- 

 stead, Essex N., May 1912. Pedicels hairy, veins recurved, styles 2. 

 Probably the hybrid. — G. C. Druce. 



C. monogyna^ Jacq., var. [Ref No. 5233.] Stow Wood, Oxford, 

 Aug. 1912.— G. C. Druce. 



Crataegus Oxyacantha^ L. (C. oxyacanthoides, Thuill.) [Ref. No. 

 748.] Hedge in fields near North Cheam, Surrey, July 11, 1912. 

 A form of this hawthorn with the leaves more cut up than usual. 

 Perhaps Mr Druce can furnish a name. — C. E. Britton. " Not 

 typical oxyncanthoides by any means, since although two styled, the 

 veins of the lower lobes mostly curve outwards, and the leaves are of 

 a dull green. There are no flowers, but I believe it is either a hybrid 

 or more probably a form of monogyna. With regard to the name 

 C. Oxyacantha, L., I may add that the specimens so labelled in Herh. 

 Linn, are all monogyna. The leaf-cutting is unusual, and I should 

 like to see flowering specimens." — G. C. Druce. 



Crataegus oxyacanthoides, Thuill., var. eriocalyx (Freyn), Druce. 

 [Ref. No. 4845.] Twinstead, Essex N., May 1912. Herr Freyn 

 named similar specimens C. Oxyacantha, L., var. eriocalyx. — G. C. 

 Druce. " Not in fruit ; apparently a clerical error for var. eriocalyx, 

 Druce, as the calyx-tube is villous. No good leaf-material. I cannot 

 help thinking that too many slight ' varieties ' are alleged." — E. S. 

 Marshall. "My label is ^ eriocalyx.^ — J. Cryer. 



Saxifraga groenlandica, L. [Ref. No. 351.] Origin, summit of 

 Mt. Brandon; cult., Sedbury, Co. Kerry, May 7, 1912.— S. H. 

 BiCKHAM. "I have growing two very distinct, densely caespitose plants 

 from this station, which appear to be good species ; they have 

 not yet flowered in cultivation, but I believe one of them to be the 

 same as this, which is the S. groenlandica of Engler's Monograph. 

 Unfortunately there is no specimen in Herb. Linn. The Spanish 

 S. groenlandica., Lapeyrouse, non Linn. {8. Tratiana, F. Schultz) is 

 clearly different ; true S. groenlandica, according to Engler, only occurs 

 in the Harz mountains, British Isles, Iceland, Greenland, and Labrador. 

 Dr Moss recently wrote to me that Ostenfeld considered >S'. groenlandica
