[swcoloradowildflowers.com] Description, Etymology: It is easily overlooked because of its overall "just green" look. A careful examination will show it to be as fascinating as other Phacelias with their protruding stamens and their often coiled, scorpion-like tails. All parts of the plant are very hairy. Plant height ranges from five to thirty inches. The genus Phacelia ("Greek for "bundle", referring to the clustered flowers) was named by Christophe Jussieu. "Heterophylla" is Greek for "different leaves", referring to the varying shapes and sizes of the plant's leaves. Phacelia heterophylla was first collected June 9, 1806 by Meriwether Lewis on the Lewis and Clark Expedition in Idaho and was named and described by Frederick Pursh in his Flora Americana in 1814.
