be followed we must write it Mespilus monogyna, Jacq., var. glab- 

 rata, Sond. In some of the Crataegi I have intentionally dried the 

 leaves and flowers only, since in the Herbarium they are, when attach- 

 ed to the woody branches, so quickly destroyed by insects. — G. C. 

 Druce. 



Cratceyus monogyna^ Jacq., var. glabrata, Sond. Hillside, and 

 frequent, Crynant, v.-c. 41, May 19, 1912. I had never detected this 

 form with glabrous calyx in Glamorgan until this date, but have 

 found an odd plant or two since near Llandaff. Perhaps it is an up- 

 land form 1 — H. J. Riddelsdell. " But my specimen has not a 

 glabrous calyx tube and is not therefore glahrata^ Sonder." — G. C. 

 Druce. 



Cratce.gus monogyna, Jacq., var. laciniata, Wallr. [Ref. No. 2.] 

 Butchers Green, Stanway, Essex N., v.-c. 19, May 21, 1912. — G. C. 

 Brown. " Not very good laciniata, the leaves should have two deep 

 sinuses on either side, and the upper part of each segment should be 

 rather deeply toothed." — G. C. Druce. 



Cratcegus monogyma., Jacq., var. kyrtostyla^ Fingerh. [Ref. No. 1.] 

 Roadside, Stanway, Essex N., v.-c. 19, May 21, 1912. — G. C. Brown. 

 "No; Fingerhutli says of his species, not variety, 'calycibus hir- 

 sutis ' : these are glabrous ; moreover, kyrtostyla is practically 

 synonymous with monogyna except for the bent style, an inconstant 

 character of trifling importance, and in these specimens some of the 

 styles are nearly straight." — G. C. Druce. 



Cratcegus monogyna, Jacq., var. kyrtostyla, Fingerh. Colley Hill, 

 Reigate, May 17, 1912. Beyond being rather more hairy on the 

 foliage, this agrees well with Fingerhuth's description and figure 

 of Crataegus kyrtostyla in Linncea (1829). I think it will be noticed 

 that the style, besides being bent or curved near the summit, is 

 rather longer than that of C. monogyna. Calyx villous. — C. E. 

 Salmon. " Even on these specimens there are many styles which 

 are straight or are only slightly bent. Some good botanists only 

 treat C. kyrtostyla, Fingh., as = C. monogyna, Jacq." — G. C. Druce. 



Cratcegus monogyna, Jacq. ("?), var. splendens, Druce. Hedge, 

 Netherton, Ross, v.-c. 36, Oct. 2, 1911. Fruit much larger than 

 usual. Perhaps the form is to be regarded as an intermediate 

 between type and variety. — H. J. Riddelsdell. Also from cliffs 

 near Redhead, Forfarshire, v.-c. 90, N.C.R., Sept. 8, 1912. [Ref. 

 No. 901.] R. and M. Corstorphine, in excursion with the British 

 Association. " Yes ; Mr. Corstorphine's specimens, which I saw 

 fresh in Forfarshire, are practically correct ; the Netherton specimen
