Geum triflorum
Geum triflorum
Geum triflorum. Synonym: Erythrocoma triflora. (Prairie Smoke, Old-Man's-Whiskers)
Rosaceae (Rose Family)

Montane, subalpine. Meadows. Summer.
Lizard Head Trail, June 19, 2004.

There is no mistaking this plant. Finely cut parsley-like leaves are surmounted by almost leafless red flower stems from which droop pink flowers that seem to be a cross between a flower, an insect, and a science fiction character. (See Artemisia scopulorum for another alien-looking plant.)  Geum triflorum seeds are borne on feathery plumes (the mature styles), as shown in the last photograph below.

Linnaeus named the Geum genus in 1753. "Geum" is a classical Latin name for some now unknown species in the Rose Family. Geum triflorum was named and described by Pursh in 1814 from a plant collected, probably in 1811 by John Bradbury in present day South Dakota (on an Astor Expedition that also included Thomas Nuttall). However, Meriwether Lewis collected this plant in Idaho on June 12, 1806 and it, too, was described by Pursh in 1814. Pursh named it Geum ciliatum. Click to read why Lewis' collection is not considered the type.

In 1906 Edward Greene renamed the species, "Erythrocoma" (Greek for "red mane"), but most botanists now accept the name Geum triflorum.
