Are Ptychosperma and Leontopodium genera?
Ptychosperma 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).
Ptychococcus Ptychococcus is a monoecious genus of flowering plant in the palm family from New Guinea and the Solomon Islands. They are closely related to "Ptychosperma", only differentiated by the seed shape and endocarp type. The name is a combination of the Greek for "fold" and the Latin for "berry".
