Spear-leaf Agoseris, Spear-leaved Agoseris, Spear-leaf Goat-chicory: Agoseris retrorsa (Synonyms: Macrorhynchus angustifolius, Macrorhynchus retrorsus)

The photo at upper left shows the involucral bracts of spearleaf agoseris. This is about as open as the flower head gets when the plant is in bloom. It's not the most showy of wildflowers. The photo at upper right shows a close-up of the achene (seed) of spear-leaf agoseris as seen along the Willard Springs Trail in Conboy Lake NWR..........July 2, 2007. Note that where the top of the achene attaches to the barb, the achene is squared off, a diagnostic feature of this species. The photo shows a basal leaf of this species. Note the numerous long hairs towards the lower half of the leaf as well as the deeply divided leaf with the lobes pointing outwards or slightly downwards towards the base of the leaf. All 3 photos show spear-leaf agoseris as seen at a DNR rock quarry at about 4100' abreast the ridgetop between the Dairy Creek and Cougar Creek drainages on the southeast corner of Mt. Adams.........May 29, 2005.
