An epiphytic species endemic to Ecuador, described by Harry Luther in 1991 and named after Jerry Raack, a prominent U.S. bromeliad collector who discovered it in 1990. The plant has an open rosette shape with soft green leaves that are discolorous, purplish on the underside, often with a waxy powder on the surface. Under high light intensity and cool temperatures, the upper leaf surface develops a deep maroon coloration. The inflorescence is nearly white, contrasting sharply against the dark wine-red foliage at bloom time. The flowers do not open and are likely pollinated by hummingbirds.
A large terrestrial species with impressive heart-shaped leaves that can reach over 90 cm in length. Leaves have a velvety texture with prominent white to pale green venation against a dark green background. New leaves emerge with a coppery-red coloration. The petioles are thick and can reach 60 cm or more.
A saxicolous bromeliad endemic to the campos rupestres (rocky grasslands) of Minas Gerais state, Brazil. Originally described as Cryptanthus regius by Elton Leme in 2007. The specific epithet regius (Latin for "royal" or "regal") refers to its distinctive appearance. This species occurs on rocky outcrops in montane environments of the Espinhaço Range. Some taxonomic treatments place this species in the genus Hoplocryptanthus.
