Are Ptychosperma and Leontopodium genera?
Leontopodium Leontopodium is a genus of plants in the Asteraceae family (which also includes daisies and sunflowers). The genus is native to Europe and Asia. The fuzzy and somewhat stocky "petals" (technically, bracts) could be thought of as somewhat resembling lions' paws —hence the genus name combining "léōn" (lion) and "pódion" (foot).
Leonaspis Leonaspis is a widespread genus of odontopleurid trilobite that lived from the Late Ordovician to the late Middle Devonian. Fossils of various species have been found on all continents except Antarctica.
