Are Frailea and Cyathodes both types of plant?
Frailea Frailea is a genus of globular to short cylindrical cacti native to Brazil. These species are cleistogamous. They were first classified in the genus "Echinocactus".
Cyathea amboinensis Cyathea amboinensis is a species of tree fern native to the Maluku Islands and possibly central and southern Sulawesi, where it grows in swamp and forest at low elevations. This species has an erect trunk, usually 2-4 m tall. Fronds are 1-2 m long and bi- or tripinnate. The stipe is warty near the base and covered with scattered scales that are dark, glossy, and have fragile edges. Sori occur near the midvein of fertile pinnules and are covered by small, dark indusia which resemble small scales.
