281. Betula papyrifera, Marshall. Paper Birch; Canoe Birch. 
Frequent; along Lake Michigan and our larger rivers. 
Wanting in the western part of our area. 
282. Betula lutea, Michx. f. Yellow Birch. 
Occasional; along streams and on the bluffs border¬ 
ing Lake Michigan.

at Cedar Bend of Root River, Racine, are several puz¬

Rare; known only from the tamarack, Wind Lake,

characteristic glandular atoms of B. glandulosa.
