What type of category does Cassiope and Pediocactus have in common?
Pediocactus Pediocactus (Greek: πεδίον (pedion) means "plain", "flat", "field") is a genus of cacti. The genus comprises between 6 and 11 species, depending upon the authority. Species of this genus are referred to as hedgehog cacti, though that name is also applied to plants from the genera "Echinocereus" and "Echinopsis". Species may also be referred to as pincushion cacti, a common name which is also applied to other genera.
Zamia furfuracea Zamia furfuracea is a cycad native to southeastern Veracruz state in eastern Mexico. Although not a palm tree (Arecaceae), its growth habit is superficially similar to a palm; therefore it is commonly known as cardboard palm or cardboard cycad. Other names include cardboard plant, cardboard sago, Jamaican sago and Mexican cycad (from Mexican Spanish "Cícada Mexicana"). The plant's binomial name comes from the Latin "zamia", for "pine nut", and "furfuracea", meaning "mealy" or "scurfy".
