REPORT FOR 1913.

smaller R. heterophyllus, the larger from the fat weak stem, and 

 undeveloped carpels, probably a hybrid, R. heterophyllus x peltatus 1 " 

 — J. Groves. 



Ranunculus peltatus Schrank, var. truncatus x ^. [Ref. No. 380.] 

 Birkdault, Haverthwaite, N. Lanes., v.-c. 69 b, July 25, 1913. Habitat 

 a few miles from the sea; not 20 feet above sea level, on the edge of Burn 

 Barren Moss where peat bog meets upland of slate rocks. Growing in 

 scarcely moving water a few inclies deep, on peaty mud — a shallow 

 drain connected by others with a tidal river in which R. truncatus is 

 abundant. A few plants of this latter species were growling with the 

 assumed hybrid. This fact, together with their further resemblance 

 in many particulars, makes it possible that truncatus is one of the 

 parents ; but I am entirely at a loss to suggest the other. Quite 

 different from anything previously described, so far as I can ascertain. 

 It may be a new hybrid, but the remarkable uniformity in the shape 

 of the floating leaves makes me hesitate to accept this view. Only 

 two sheets out of twenty-four contain a floating leaf slightly differing 

 in shape from the normal. — W. H. Pearsall. " Near to elongatus 

 W. P. Hiern." — F. A. Lees and A. Bennett. " Probably a hybrid 

 with R. peltatus as one of the parents." — J. Groves and J. A. Wheldon. 

 "Probably R. peltatus, var. truncatus x Lenormandir — E. S. 

 Marshall. 



Ranunculus peltatus Schrank, var. penicillatus (Hiern) % [Ref. 

 No. 3909.] Pond below Cheddar Gorge, v.-c. 6, N. Somerset ; in 

 excellent flower and fruit. Petals large, often truncate at the apex. 

 Carpels with long, spreading, mostly deciduous hairs. Leaves dark 

 green, collapsing into a " pencil point " ; no floating ones, however 

 still the water may be. In the Flora of Somerset this (under the 

 name of R. pseudo-Jiuitans Bab.) is referred to as having " rigid " 

 segments to the leaves ; but in no instance did I find this to be so. 

 Probably it may vary, according to the season. — E. S. Marshall. 

 " Not I think a form of R. peltatus. In 1891 my brother collected a 

 Batrachium at Cheddar, which seemed best referred to Hiern's form 

 32 sphaerospermus, and probably the present plant is an autumn state 

 of this in which the leaves have somewhat lengthened out." — J. 

 Groves. "This appears to be a robust form of the Oxon (4912) 

 plant. The true penicillatus should have floating leaves." — G. C. 

 Druce. 



Ranunculus peltatus Schrank, var. truncatus (Hiern). Biggar road- 

 side, Walney I., v.-c. 69, May 22, 1913. Flowers with eleven, twelve, 

 and thirteen petals were abundant. — D. Lumb. "Yes, towards var. 

 truncatus. The carpels of this and of Mr Lumb's plant from Breast 

 Mill Beck are glabrous which is most unusual with R. peltatus,''
