NOTES ON THE PLANTS GATHERED IN 1881. 
EDITED BY 
F. ARNOLD LEES, M.R.C.S., L.R.C.P., F.L.S. 
Thalictrum flavum , L., vars. Seavy Carr and Potteric Carr, 
Doncaster, W. Yorks., July, 1881. — F. A. Lees. “The Seavy Carr 
specimen is probably var. spharocarpum from the great breadth of 
the leaflets, but uncertain from the achenes being converted into 
galls, as so often occurs in Thalictra. Dr. J. A. Power sent 
Perthshire specimens of Thalictrum flexuosu??i l affected in this 
way, to the chief authority on Galls, Mr. E. A. Tetch, Brick House, 
Maldon, Essex, who said they were produced by a Dipterous fly 
belonging to the genus Cecidomya ; but the species could not be 
determined as the galls were empty. They should be sent before 
they are pierced by the exit of the fly. The peculiar appearance of 
the Potteric Carr specimen is doubtless caused by some injury to the 
main stem.” — J. T. Boswell. 
Ra 7 iunculus penicillatus , Fr., Ditch by Colne, Rickmansworth, 
Herts, June, 1881. — E. de Crespigny. 
Ranunculus diversifolius a. radians , Hiern. Pools near Coles- 
hill, Warwick, 21st June, 1881. — J. E. Bagnall. “A name quite 
unintelligible to me. This is not radians, Rev., neither I think of 
Hiern. It is a common form of heterophyllus P — C. C. Babington. 
Ranunculus trichophyllus , Chaix., and R. radians , Revel. Pond 
at Floors, Roxburgh, June and July, 1879. To shew that these are 
the same plant at different ages, see B. E. C. Reps., 1875-6-9. — A. 
Brotherston. “ I have no doubt trichophyllus, radians , and Godronii, 
of British authors, are merely states of one plant and interchangeable. 
Grisebach, in the posthumous fragment, “ Flora Europea,” refers 
Ranunculus Godronii to Ranunculus ololeucos , Lloyd, which as well 
as Ranunculus Petiveri, K. ; and Ranunculus confusus, Godr., he in- 
cludes under Ranunciilus triphyllos , Wallr.” — J. T. Boswell. 
Ranunculus triphyllos, Wallr. Ditches near Coventry, Warwick, 
July, 1881. — J. E. Bagnall. “No. A form of heterophyllus. What 
is 4 Lon. Cat.’ I do not know.” — C. C. Babington. “ I cannot 
distinguish from ordinary heterophyllus, as I understand it.” — J. G. 
Baker. “This is Ranunculus heterophyllus, Fries, E. B., ed. III., 
with glabrous or sub-glabrous achenes.” — J. T. Boswell.
