   Packera species were for a considerable time placed in the Senecio genus.  The Flora of North America and The Synthesis accept William Weber's 1981 genus name, Packera, but Intermountain Flora and A Utah Flora still accept Senecio as the name of this genus. 

   John Packer was a Canadian botanist.  (More biographical information about Packer.)

Common in Canyon Country in mid-spring, Packera multilobata produces small but numerous bright yellow flower heads atop many, deeply cut, lobed leaves.  Packera multilobata brightens shady Cottonwood groves, Pinyon/Juniper forests, and open, sandy, arid areas.

"Multilobata", Latin, means "many lobed" and refers to the numerous leaf indentations (which commonly have a blue cast to them). The upper side of the leaves shown below is arachnoid (cobweb-like) hairy; the underside is glabrous. Typically the entire plant is glabrous with some hairiness in the leaf axils.

John Fremont collected the first specimens of this plant for science in the 1840s in California and John Torrey and Asa Gray named the plant Senecio multilobatus in 1849.  In 1981 Weber and Löve removed a number of species from the Senecio genus and placed them in a new genus, Packera.
