Thevetia and Nomocharis, have which mutual detail characteristic?
Thevetia Thevetia is a genus of flowering plants in the dogbane family, Apocynaceae, first described for modern science as a genus in 1758. It is native to Mexico, Central America, South America, and Cuba. The taxonomy of the genus is controversial, with some authors including "Cascabela" within "Thevetia", while others accept the two genera as separate.
Polygonia Polygonia (from Greek πολύς - "polys", "many" and γωνία - "gōnia", "angle") is a genus of butterflies with a conspicuous white mark on the underside of each hindwing, hence the common name comma. They also have conspicuous angular notches on the outer edges of their forewings, hence the other common name anglewing butterflies. The related genus "Nymphalis" also includes some anglewing species; "Polygonia" is sometimes classified as a subgenus of "Nymphalis".
