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).
Stypopodium Stypopodium is a genus of thalloid brown alga in the family Dictyotaceae. Members of the genus are found in shallow tropical and subtropical seas around Africa, Pakistan, India, Japan, Indonesia, Australia, Micronesia, the Caribbean, Venezuela and Brazil.
