Pryus sambucifolia. Elderleaf Mountain Ash. 



Leaves odd-pinnate; leaflets 7 to 15 oblong-ovate, mostly 

 obtuse. Flowers appear in July in small dense pubescent 

 cymes. The fruit is globose, bright s'carlet and sometimes 

 nearly a half inch in diameter. It is produced in dense red- 

 branched clusters and remains on the tree into the winter. A 

 small tree that is often mistaken for Pyrus americana, from 

 which it is best distinguished by its smaller cymes, its larger 

 and later flowers and its more obtuse and broader leaflets. 



Jhstribution. It is found growing from southern Green-

 northern shores of the Great Lakes to Little Slave Lake
