Family Hydrophyllaceae

The waterleaf family, containing 17 genera and about 250 species. Usually annual herbs, occasionally shrubs. The placement of this family in order Solanales is a bit controversial; some scientists merge the Hydrophyllaceae with family Boraginaceae under order Boraginales.

Hydrophyllaceae's seventeen genera can be organized into subfamilies and tribes, listed below. However, since I could find no associations besides the obvious ones, I did not try to inject the subfamily and tribe names into the list of genera.

Subfamily Hydroleoideae (sometimes put in its own family, Hydrolaceae)

  • Tribe Hydroleeae
  • Tribe Wigandieae
Subfamily Hydrophylloideae
  • Tribe Hydrophylleae
  • Tribe Romanzoffieae (Phacelieae)
Subfamily Namoideae
  • Tribe Nameae
