Arnica angustifolia ssp. angustifolia Vahl
26 photos.
This is the "narrowleaf arnica".  Hulten lists two subspecies (angustifolia and attenuata) of Arnica
alpina as being present in this area.  Attenuata is distinguished by having multiple flowers. Both subspecies
have been reclassified as Arnica angustifolia, ssp angustifolia.   The photos below show plants with leaves that are
narrow and also plants with broader leaves.  The broad-leaved plants have multiple blossoms as do some
of the narrow-leaved plants so I assume they are plants which were formerly classified as A.alpina ssp attenuata
and are therefore A. angustifolia.  ITIS indicates that a species A. alpina (TSN 36556) is present in Alaska.
The Global Biodiversity Information Facility has information showing that Arnica alpina (L.) Olin is present
in this area, however these specimens may be A. angustifolia.  FNA does not list A. alpina.
