appearance of peltatus, but the submerged leaf-segments are capillary 

 and collapsing, and the rather small flowers indicate a heterophyllus — 

 parentage. It should be collected again two or three weeks later." — 

 E. S. Marshall. " My specimen is not a good one, but there appears 

 to be a suggestion of heterophyllus" — G. C. Druce. " The rather fat 

 stem and the undeveloped carpels point to hybridity, in which case no 

 doubt R. peltatus is one parent, but there is not sufficient evidence by 

 which to suggest the other. I think Batrachian hybrids must be 

 made out on the spot." — J. Groves. 



Ranunculus peltatus^ Schrank, var. d. penicillatus^ Dum. 

 Cuxham, Oxford, June 1912. — G. C. Druce. "Not in the least like 

 B. penicillatum, Dumort., which has 'feuilles submergees flasques a 

 segments allongees et se reunissenten pinceau horsdel'eau.' I should 

 not refer Mr Druce's plant to R. peltatus but should like to see fruit 

 before expressing a definite opinion. There is no information as to 

 habitat but I presume it occurs in running water." — J. Groves. "I 

 am in considerable doubt about this plant and will collect it again." — 

 G. 0. Druce. 



Ranunculus Hiltoni, H. & J. Groves. Abundant in a small pool 

 on border of Copthorne Common, Sussex E., v.-c. 14, April 1912. J. 

 Comber. " Doubtless, R. Lenormandi x peltatus." — E. S. Marshall. 

 "Yes; excellent specimens." — J. Groves. 



Ranunculus hederaceus, L., var. omiophyllus, Ten. Floating in 

 about 2 ft. of water, ditch near Mayford, Surrey, v.-c. 17, April 1912. 

 — J. Comber. "A state, rather than a good variety." — E. S. Mar- 

 shall. " The floating state of R. hederoceus which goes by this name. 

 Mr Hiern describes his form homoeophyllus as having the style termi- 

 nal and that of hedercefolius as lateral, but the outline of the carpels 

 and the direction of the styles vary considerably in the same head." — 

 J. Groves. 



Caltha palustris, L., forma. Boggy ground, Penyfae Common, 

 Bridgend, v.-c. 41, May 1912. I do not think it is one of our named 

 varieties, and indeed it may only be a form, though local conditions 

 afibrd no good reason for the reduction in size, etc. — H. J. Riddels- 

 dell. 



Actoia spicata, L. Amongst limestone rocks near Ribblehead, 

 altitude 1000 ft., v.-c. 64, May 25, 1912. In fair abundance.— J. 

 Cryer. 



Fapaver Rha^as, L., forma. [Ref. No. 795.] Banstead, Surrey, 

 July 28, 1912. Probably identical with the Poppy, from the same
