Geum aleppicum Jacquin
(Yellow Avens)
Family: Rosaceae
Status: Native
Synonyms:

Geum strictum Aiton var. decurrens (Rydberg) Kearney & Peebles (nom. illegit.)
Geum aleppicum has flowers with jointed styles, with the upper part less than half the length of the lower segment. It is found in moist wooded areas at middle elevation. It looks very similar to Geum macrophyllum var. perincisum. There are some differences in leaf shape, but the best field character is the presence of hairs obvious with a hand lens on the distal style segment on Geum aleppicum and missing on the style of Geum macrophyllum var. perincisum.
