Barnadesioideae is a subfamily of flowering plants in the aster family, Asteraceae. It comprises a single tribe, the Barnadesieae. The subfamily is endemic to South America. Molecular evidence suggests it is a basal clade within the family,[1][2] and it is monophyletic.[3]

The subfamily includes species of annual and perennial herbs, shrubs, and trees up to 30 meters tall. Most are likely pollinated by hummingbirds.[3]

Phylogeny

Genetic analysis has included increasing numbers of taxa and involved a growing number of genes. The relationships of the genus Schlechtendalia could so far not be resolved. The following tree reflects the current scientific insights and Schlechtendalia can be found in two possible positions.[3]

gollark: Which forums?

gollark: I am using a one file one, I don't think it's recent though.

gollark: Currently I believe my stuff is using some random outdated build from ages ago, and not benefiting from new improvements to verification speed.

gollark: Some sort of convenient standalone ECC library for potatOS and stuff would be neat too.

gollark: In what way? Because both use OpenGL?
