CAYUGA FLORA (1926) NOTES: Acid or neutral well-drained soils; rare. May 15-30. Not known to Dudley, but clearly native at the top of the high hill 1.5 miles s. w. of West Danby, where it is abundant. It occurs also in considerable quantity just outside the Cayuga Lake Basin in the n. w. corner of Cayuta Township on the road from Ithaca to Elmira. A single small tree was found in a field, s. side of Fall Creek below Varna. Newf. to Alaska, southw. to Pa., Nebr., and Wash., including the northern Atlantic Coastal Plain. This species is doubtfully distinct from B. alba L., but in recent years has been more commonly so treated.
