4 HOBKIRK: DISAPPEARANCE OF PLANTS IN YORKSHIRE. 
remark that ‘the partial or complete extirpation of ferns forms a con- 
siderable portion of the lists of the Committee’s correspondents, the 
tourist in part, but in a greater degree the “collecting dealer,” being 
held responsible. The Committee also particularly regrets to have 
to draw attention to the rapidly approaching extermination of 
Cypripedium caiceolus and hopes that strenuous efforts will be made to 
protect it in its few remaining stations.’ This being a Yorkshire 
plant—or at any rate a recorded one—is well worthy of our attention. 
The British Association Committee further remark that its ‘ various 
correspondents are practically unanimous in expressing a wish that in 
some way the law of trespass or of wilful damage should be brought 
to bear upon the ‘collecting dealer’ without the systematic ravages 
of whom they believe that any approach to extermination avould in 
most cases be impossible.’
