to the occurrence of H. murorum var. fdlucidum on oolitic 
hills above Wotton-under-Edge and Dursley, where type 
vulgatum is also plentiful. And Mr. Hanbury, in his Mono-

flexicaule (not a native) on an old garden wall in Clifton, 
where it still exists.

EEICACE^. 
Pyrola minor was discovered in N. Somerset by Mr. E. 
Baker in 1883. He and I then traced it about 100 yards in 
a wood near Abbotsleigh where the underwood had recently 
been cut. It was not until July 1898, that I saw this plant 
in Gloucestershire. After a steady hunt about Woodmancote 
at Dursley, Mr. D. Fry and I found plenty of it on the lower 
slopes of a wood, occurring here and there for about a mile. 
We did not find P. media. 
Vaccinium Oxycoccus L. {Oxycoccus palustris Pers., SchoUera 
Oxy coccus Eoth.). Formerly known on Burtle and Shapwick 
turf-moors, and stated to have been gathered on Blackdown, 
Mendip, in August 1860. The Cranberry appeared to be 
lost to us until June 1896, when Mr. W. F. Miller sent me a 
specimen gathered by him amongst Sphagnum on the side 
of Blackdown [Journ. Bot., 1896, p. 319).
