Phacelia tanacetifolia

Benth.

Boraginaceae


This species was traditionally placed in the family Hydrophyllaceae. However, research in the early 21st century has recognized its close affinity with the family Boraginaceae and has demoted its rank to a subfamily of the Boraginaceae. We have adopted this treatment here, but some authorities have maintained the family Hydrophyllaceae as distinct and there is some chance that it will be reinstated[
