The subject of our illustration, Amelanchier oligocarpa, is 
a denizen of cold swamps and mountain bogs from Labrador 
southward to the shores of Lake Superior and the northern 
portion of New York State. In habit it is the most low- 
growing species of its genus, and coming as it does from a 
more northerly habitat than any other, it 1s exceedingly 
hardy. Yet it has always been one of the rarest of shrubs 
in our collections, some form of A. canadensis, Torr. & Gray, 
being as a rule supplied under the name, a circumstance 
which may perhaps have helped to account for its occasional 
treatment asa variety of A. canadensis. In spite of this, 
A, oligocarpa is singularly unlike A. canadensis, and is well — 
and easily distinguished by the few-flowered inflorescences 
with one to three, very rarely four blossoms. The species 
thrives best in a good loamy soil. The plant from which
