Both Anisacanthus and Holodiscus are what level of classification?
Anisacanthus Anisacanthus is a genus of flowering plants in the bear's breeches family, Acanthaceae. The generic name is derived from the Greek words ανισος ("anisos"), meaning "unequal," and ακανθος ("acanthos"), meaning "thorn." Members of the genus are native to tropical and subtropical regions of the Americas. They are commonly known as desert honeysuckles, though this term is shared with the genus "Ancistranthus", and is something of a misnomer as true honeysuckles (genus "Lonicera") belong to the family Caprifoliaceae. "Anisacanthus" species are sometimes cultivated for use in xeriscaping.
Ankylopollexia Ankylopollexia is an extinct clade of dinosaurs within the order Ornithischia that lived from the Late Jurassic to the Late Cretaceous. It is considered a more derived clade of iguanodontians and contains the subgroup Styracosterna and Hadrosauriformes. The name stems from the Greek word, “ankylos”, meaning stiff, fused, and the Latin word, “pollex”, meaning thumb. Originally described in 1986 by Sereno, this most likely synapomorphic feature of a conical thumb spine defines the clade. Many ankylopollexians have not yet been placed in the phylogeny because of the lack of data on the specimens or simply just not analyzed yet. One of the most famous and most derived members of the Ankylopollexia clade is the "Iguanodon".
