7 Picea australis Small, Southern Spruce, characterized by J. K. Small (Flora Southeastern States, 30, 

 1903), appears to be closely related to Picea rubra, and may prove to be a distinct species. I have not seen 

 the tree nor specimens of it. Picea alba Chapman (Flora Southern States), not of Link, so far as now 

 known, occurs on the high slopes and summits of mountains in Virginia and North Carolina.
