 R. ULMiroLiirs x caesius, a hybrid, occurs near Bagley Wood along the 

 Abingdon Road, and on the Eynsham Road. Various names had been 

 suggested for the plant till, on the occasion of Dr. Focke's visit in 1894, 

 he told me he considered it to be a hybrid of the two species (both of 

 which occur there) ; the plant is very frequently barren or only a few 

 drupes are found ; the flowers are often tinted with pink.
