question: Are Ptychosperma and Leontopodium genera?
answer: yes
context: Title: Leontopodium
  Passage: 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).
  Title: Ptychosperma
  Passage: Ptychosperma is a genus of flowering plant in the Arecaceae family.  Most are native to Australia and/or New Guinea, with a few in the Solomon Islands and in Maluku Province of eastern Indonesia.  Some have been cultivated abroad as house or garden plants, and reportedly naturalized in certain regions (Caribbean, Polynesia, Fiji, Florida).
