carpels inflated at the end ; style straight. All these characters 

 favour R. Drouetii.'' — E. S. Marshall. "Characteristic. The 

 collapsing or non-collapsing of the leaves depends upon the mineral 

 contents of the water." — J. A. Wheldon. " Yes ; trichophyllus'' — 

 J. Groves. 



Ranunculus trichophyllus, Chaix, forma terrestris. On mud by 

 the stream near Brockenhurst, S. Hants, June 1912. — G. C. 

 Druce, " Another terrestrial state. There is only one decent 

 peduncle in these specimens and that is long and weak, unlike that of 

 normal trichophyllus." — J. Groves. 



Ranunculus heterophyllus, 'Wohav, forma terrestris. [Ref . No. 4809.] 

 Near Cheltenham, Gloster W., June 1912. Growing on mud, the 

 type was in the pond. — G. C. Druce. " Possibly, but why 

 collect these wretched terrestrial states and not the normal aquatic 

 plant r' — J. Groves. 



Ranunculus heterophyllus, Weber. [Ref. No. 7612.] Twinstead, 

 Essex N., May 1912.— G. C. Druce. " Yes."— J. Groves. 



Ranunculus heterophyllus, Weber, /orma. Pond, Peldon, Essex N., 

 v.-c. 19, May 14, 1912. [Ref. No. 12.] Growing intermixed in 

 same pond with Ref. No. 11. — G. C. Brown. "Yes." — J. A. Wheldon. 

 "Yes ; a form with glabrous carpels." — J. Groves. 



Ranunculus heterophyllus, Weber, forma or var. Pool in field, 

 near Little, Stanney, The Wirral, Cheshire, v.-c. 58, May 11, 1912. — 

 C. Waterfall. " Yes ; typical, but gathered early." — E. S. Marshall. 

 " This is Batrachium diversifolium, Hiern = R. Godronii, Gren." — J. A. 

 Wheldon. " Yes ; I should say a weak form of R. heterophyllus. 

 One would like to know if it were crowded together, which might 

 account for its tenuity." — J. Groves. 



Ranunculus peltatus, Schrank. [Ref. No. 6602.] Twinstead, 

 Essex N., May 1912.— G. C. Druce. " Yes ; but too young : no fruit." 

 — J. Groves. 



Ra7iu7iculus peltatus, Schrank. [Ref. No. 10.] Shallow pond, 

 Langham, Essex N., v.-c. 19, May 5, 1912.— G. C. Brown. " Yes."— 

 J. Groves. 



Ranunculus peltatus, Schrank. x % [Ref. No. 13.] Pond, Weeley, 

 Essex N., V. c. 19, May 16, 1912. I think there is little doubt of its 

 hybrid origin, though I believe no other species occurs in the pond. 

 — G. C. Brown. "Very likely R. heterophyllus x peltatus; general
