parison with Lindley’s type, preserved at Cambridge, 
leaves us in no doubt that Koehne’s name must be 
reduced. <A. florida grows freely at Kew, and flowers 
regularly and profusely every year. It is a charming 
shrub, easily accommodated and thriving well in loamy 
soil, useful for situations where A alnifolia and A. cana- 
densis might be too large. It produces good seeds 
freely under cultivation and by them is readily pro- 
pagated. A. florida appears to be one of the most widely 
spread of North American Amelanchiers. It is found 
in wooded districts of British Columbia, Oregon and 
Washington, extending southwards to Nevada and east- 
wards as far as Michigan.
