Perityle is a genus of flowering plants in the daisy family.
They include small herbs to spreading shrubs and most bear yellow or white daisylike flower heads.
The fruit is generally a flat seed with thickened margins which may or may not have a pappus or scales.
[5] A study including morphological and cytological analyses and a phylogenomic analysis of chloroplast and nuclear genomes was published in 2022, and concluded that Perityle as previously circumscribed was polyphyletic.
The authors revived and/or expanded the genera Galinsogeopsis, Laphamia, and Nesothamnus to establish monophyletic clades.
