Question: Are Tweedia and Nematanthus both a genus of flowering plants?
Sentence (from "Austrobaileyales"): The order belongs to the group of basal angiosperms, the ANA grade, which diverged earlier from the remaining flowering plants, and, as such, it is the extant group after the Amborellales and Nymphaeales, that is sister to all remaining extant angiosperms outside of the ANA grade.
Relevant evidence: No
