Yorkshire Naturalists’ Union: Annual Report, 1910. 59 
The species has been confirmed by Mr. F. A. Lees. Neottia 
midus-avis Rich. was found in Edlington Wood. 
A change in the local florula is now taking place on 
Thorne Waste. A part of the old peat bog is being “ warped,” 
and where two years ago were to be found A ndromeda polyfolia, 
Drosera rotundifolia, Carex curta and other peat lovers. are 
now Aster Tripolium, Rumex maritimus, Atriplex hastata, Scirpus 
maritimus, and other maritime plants. These will doubtless have 
only a short period allowed them, and will soon be succeeded by 
cultivated crops and their associated casuals. 
The following were elected for 1911 :— 
President—Dr. T. W. Woodhead, Huddersfield. 
Secretaries—H. H. Corbett, 9 Priory Place, Doncaster; J. 
Fraser Robinson, 22 Harley Street, Hull ; 
Representative on Executive—E. Snelgrove, Sheffield. 
Representative on Committee of Suggestions—S. Margerison, 
Leeds. 
Botanical Survey Committee.— Dr. T. W. Woodhead writes :-— 
The ecologists have been particularly active, and the result of 
their work is reflected in nearly every number of ‘“‘ The Naturalist ”’ 
for the current year. Mr. Frank Elgee’s interesting observations 
on Heather Moors of North East Yorkshire were published in 
the January and February numbers, under the title of “‘ The 
Vegetation of Swiddens,”’ and show how areas which have been 
burnt become colonised, often by species which only temporarily 
occupy the ground, these being in turn driven out by one or other 
of the characteristic species of the Heath vegetation. This 
paper called forth some observations by Dr. H. F. Parsons on 
“The Effects of Heath Fires on Vegetation ”’ (“ } Nat.,’ ” March). 
Mr. W. M. Rankin’s contribution on the ‘“ Peat Moors of 
Lonsdale” (“ Nat.,’’ March and April), gives a very suggestive 
account of these moors, in which he distinguishes two Formations * 
(x) The Swamp Moor Formation, and (2) The Heath Moor Forma- 
tion, each with associations of (a ) Lacustrine, and (bd) Estuarine 
and Littoral origin. The paper is illustrated by six photographs. 
Dr. C. E. Moss’s paper on the species and varieties of Quercus, 
is valuable in that it shows the importance and significance of the 
distinctive characters of these forms when considered in connection 
with their distribution (see “‘ Nat.,’’ April). 
Dr. Wm. G. Smith’s excellent notice of Adamovic’s work 
on the vegetation of the Balkan lands, calls attention to the in- 
fluence of tectonic factors, which are of great importance in the 
study of vegetation (see “ Nat.,” July). 
An admirable account of the Woodlands of England has been 
published by Messrs. Moss, Rankin & Tansley, which will be of 
great service to all interested in these constituents of our vegeta- 
tion. ) (For amotice of this'see Nat: for Sept:):
