Hackelia floribunda (Hackel's Stickseed)
Boraginaceae (Forget-Me-Not Family)

Montane. Openings. Summer.
Priest Lake, July 14, 2008.

Hackelia floribunda and Hackelia micrantha are very similar.  The plants shown have some characteristics of H. micrantha (strongly perennial and numerous stems) but fit botanical keys best for H. floribunda.  Weber and Kartesz also indicate that there are no confirmed specimens of H. micrantha within a hundred miles of the plants shown at left. The nutlets are essential in separating the two species, but I have not been able to collect these.

The plant was first named Echinospermum floribundum by Johann Lehmann in 1830 from a specimen collected by Thomas Drummond in Canada in the 1820s.  The plant was renamed Hackelia floribunda by Ivan Johnson in 1923. Joseph Hackel was a Czech botanist.

Seeds are quite prickly and seed stems are "secund", i.e., they curve around the main stem to all face in the same direction.
