Abnormal Form o/Listera cordata. 57 



have in this paper shown that it is developed in L. 

 cordata. 



Dr Masters, in his Vegetable Teratology, makes no 

 mention of having observed polyphylly in any species of 

 the genus Listera. 



The specimens of L. cordata wliich I have referred 

 to were sent to me by my freind Mr S. A. Stewart of 

 Belfast, and they were gathered by him in a peat-bog near 

 Donaghadee, co. Down. 



On certain Additional Localities for Cornish Plants. By

 Curator of the University Herbarium, Cambridge. 



(Read 10th May 1883). 



The only recent printed information to be obtained re- 

 garding the plants of Cornwall, is that which is recorded 

 in the Flora of Devon and Cornivall, published during the 

 years 1865-71 by J. W. N. Keys of the Plymouth Insti- 

 tution and Devon and Cornwall Natural History Society, 

 Since the appearance of this work Mr J. G. Baker has 

 contributed to the Journal of Botany a very valuable list 

 of the plants observed by himself, Messrs T. Archer Briggs, 

 and A. W. Bennett, in the Lizard Peninsula, and one of 

 the latter gentlemen has dealt with those of the extreme 

 south-eastern corner in his Flora of Plymouth. The E,ev. 

 C. A. Johns also, in his charming book, entitled A Week 

 at the Lizard, has given an account of those species which 

 Mr Curmack of Helston and he himself had observed. It 

 is much to be regretted, however, that no complete jflora 

 of this most interesting county at present exists, and it is 

 to be sincerely hoped that before long this desideratum 

 will be supplied at the hands of local botanists. Under 

 these circumstances, I ofifer the following list as a small 

 contribution towards a more complete knowledge of the 

 plants of this county. The i)lants mentioned from the 

 Lizard district are supplementary to those of Mr Baker's 

 list,* which I found of great value. My visit was made
