thence to the N. Devon border at Coryton ys 
Bridestowe. Not observed by me in the county until 1910, eon 
two or three years nie I suggested the name for a plant collected 
by Mr. G. B. Savery between Yellowford and fection Speke (°). 
Its exact position and rank in our list is provisional pane 
seems as nearly allied to &. pubescen s and FB. macrostemon a 
Godront, and in Dr. Focke’s Mittelerop. Rubi (1902) t "the 
name appears as a seucenes of rost
