Which genus has more species, Cyananthus or Polypodium?
Polypodium Polypodium is a genus of 75–100 species of true ferns, widely distributed throughout the world, with the highest species diversity in the tropics. The name is derived from Ancient Greek "poly" (πολύ) "many" + "podion" (πόδιον) "little foot", on account of the foot-like appearance of the rhizome and its branches. They are commonly called polypody or rockcap fern, but for many species unique vernacular names exist.
Paphinia Paphinia, abbreviated in horticultural trade Pna, is a genus of orchids, composed of an estimated 16 species from Central America, northern South America and Trinidad. These species are medium-sized epiphytes with small ovoid pseudobulbs and 2 or more leaves. The generic name comes from the Greek "Paphia", the name of Aphrodite of Cyprus. Most authorities consider the genus rare.
