Ranunculus heterophyllus Weber. [Ref. No. 106.] Quarry pool, 

 near Auldbar, Forfar, Aug. 1913. Floating leaves not typical, almost 

 all tripartite. — R. and M. Corstorphine. "Yes." — J. Groves. "A 

 curious plant which suggests trichophyllus. The flowers are small, 

 can it be a form of R. radians Revel ^ " — G. C. Druce. 



Ranunculus % [Ref. No. 105.] Quarry pool, near Aberlemno, 



Forfar, Aug. 1913. In 1910 this buttercup was sent to Messrs 

 Groves who said "The long tapering peduncles will not do for R. 

 heterophyllus. We think it is a hybrid." There are no other butter- 

 cups near it. The plant is the same as when we last gathered it three 

 years ago, except that the floating leaves are not so sharply or so 

 deeply cut. — R. and M. Corstorphine. "I think a form of R. 

 Baudotii, from the size of the flowers, double curve of the peduncles 

 and the practically glabrous carpels." — J. Groves. 



Ra7iunculus 1 [Ref. No. 112.] Ditch near Guthrie, Forfar, 



Aug. 1913. The ditch was so dry that the submerged leaves were 

 out of the water. The fruit was very scarce. —R. and M. 

 Corstorphine. " Was trichophyllus or typical heterophyllus in the 

 same locality ? It suggests the hybrid between these two." — G. C. 

 Druce. "I think a hybrid with R. heterophyllus as one of the parents. 

 There is no developed fruit. The curiously drawn-out appearance is 

 probably due to growing under unusual conditions." — J. Groves. 



Ranunculus heterophyllus y^QhevI Biggar roadside, Walney I., 

 v.-c. 69, May 22, 1913. Growing with R. truncatus, var. peltatus. — 

 D. LuMB. " Apparently two plants here, the one having short 

 peduncles and the fruit undeveloped, the other with long peduncles 

 and glabrous carpels : the first would be R. heterophyllus or a hybrid, 

 the second, I take it, the same as the following plant, from the same 

 locality, sent as R. peltatus^ var. truncatus V — J. Groves. 



Ranunculus triphyllus Hiern. Mouzell, Dalton, v.-c. 69, May 28, 

 1913. — D. LuMB. "Should probably be referred to f. 12 triphyllus 

 Hiern, although some of the carpels are quite bristly. Mr Hiern 

 should not be cited as the authority for the specific name, as he 

 named it as a form based on R. triphyllos Wallroth." — J. Groves. 



Ranunculus peltatus Schrank. Breast Mill Beck, Dalton, v.-c. 69, 

 May 29, 1913. — D. Lumb. "Yes." — J. Groves. "Yes, approaching 

 truncatus^ — G. C. Druce. 



Ranunculus peltatus Schrank? Raikes Moor, Dalton, v.-c. 69. 

 Floating leaves markedly less circular in outline than are those of the 

 Breast Mill Beck plant. — D. Lumb. " Apparently two plants, the
