  • COSEWIC Assessment and Status Report on the Nahanni Aster Symphyotrichum nahanniense in Canada (2014)
    Nahanni Aster is a perennial wildflower up to 35 cm tall with white to pale pink flower heads. It typically grows in clumps of about two to ten stems from short, woody rhizomes (horizontal underground stems). The stems are branched to form an open panicle typically with one to three flower heads, but some plants have 15 or more. The number of flower heads appears to vary between sites and may be determined by growing conditions. The stems are gre ...
  • COSEWIC Assessment and Status Report on the Copper Redhorse Moxostoma hubbsi in Canada (2014)
    The copper redhorse (Moxostoma hubbsi) is one of seven species of the genus Moxostoma (family Catostomidae) occurring in Canada. Its discovery has been attributed to Vianney Legendre in 1942 (Legendre 1942), but it appears to have been first described by Pierre Fortin in 1866 as an already known species of the genus Moxostoma.
