Dear Michael,

No, it was proposed some years ago on the basis of petal venation.
But the more convincing evidence comes from pollen morphology, leaf
anatomy, and geography.

Yes. I have accepted it since 1995, when Cameron & al. showed (by
genetic comparison) it to be closer to the pair Ancistrocladaceae/
Dioncophyllaceae than to Droseraceae. There is not even morphological
support for its inclusion in Droseraceae (v.s.).

_Byblis liniflora_ s.lat.

Kind regards
Jan
