Of Fir and Canistrum, which is of the botanical family Bromeliaceae?
Fir Firs (Abies) are a genus of 48–56 species of evergreen coniferous trees in the family Pinaceae. They are found through much of North and Central America, Europe, Asia, and North Africa, occurring in mountains over most of the range. Firs are most closely related to the genus "Cedrus" (cedar). Douglas firs are not true firs, being of the genus "Pseudotsuga".
Berberis canadensis Berberis canadensis, commonly known as the American barberry or Allegheny barberry, is a member of the family Berberidaceae. "Berberis canadensis" is the only simple-leaved "Berberis" indigenous to the United States. The epithet "canadensis" literally means "Canadian" but was often used by 18th-Century botanists to refer to any plants growing in northeastern North America
