A NEW WEST YORKSHIRE PLANT 

 (PYROLA ROTUNDIFOLIA).

By favour of Air. Trevor Basil Woodd I am glad to be able to place 

 on record an observation of that gentleman's, which makes a genuine 

 addition to our list of West Riding plants. In my ' Flora ' I 

 considered it justifiable to express grave doubts whether true Pyrola 

 rot undif alia L. occurred in W. York at all, seeing that every previous 

 record made under that name had turned out, upon investigation of 

 herbarium specimens or plants growing in the assigned stations, to 

 be either Pyrola media or P. mmor — species either confused with or 

 classed under ' rotimdifolia' by early botanists. Now, however, 

 Mr. Woodd has kindly sent me green flowering examples of a Pyrola 

 which grows ' on the damp slopes of the wood at Outershaw (in 

 Langstrothdale), sloping down to the Wharfe, 1,200 ft. above the sea.' 

 This is a new station, not one of those previously recorded for either 

 P. media or P. minor ; and by its much decurved pink styles, with a 

 raised ring at the tip bounding the base of the stigmatic cone, its 

 small round leaves, and longish fine-pedicelled flowers, the petals of 

 which open out more than in P. minor, the species is undoubtedly 

 true Pyrola rotundifolia. The altitude at which it grows is fully 

 300 ft. greater than any known hitherto for the round-leaved section 

 in Yorkshire, but in the highlands of Scotland, according to Hooker, 

 Mr. Woodd's plant is found as high as 2,000 ft.
