Heliotropiaceae
From Wikipedia, the free encyclopedia
Heliotropiaceae are a cosmopolitan family of flowering plants with approximately 450 species worldwide, though it is concentrated especially in the tropics and subtropics.[1]
The following are the four genera in the family:
- Heliotropium (incl. Tournefortia L.)
- Euploca Nutt.
- Ixorhea Fenzl
- Myriopus Small
Ixorhea is sister to Euploca and Myriopus.[2] Together they form a clade sister to Heliotropium, which comprises four major clades: Heliotropium sect. Heliothamnus I.M.Johnst., Old World Heliotropium, Heliotropium sect. Cochranea (Miers) Post & Kuntze, and the Tournefortia-clade, the latter comprising Tournefortia sect. Tournefortia and all remaining New World species of Heliotropium.[3][4]
