canina. It is connected with Rosa canina L. by Rosa obtusifolia Desv., 
which may be regarded as a uniserrate form with white flowers. 
Mr. Baker gathered it in many parts of England, from the Isle of 
Wight northward to Northumberland. According to Crepin and 
Christ, it extends to Persia, where it has been found by Dr. Hauss- 
knecht at a height of 8,000 feet above sea-level. It is common in 
France and Switzerland.
