# Cryptanthus

Cryptanthus is a genus of flowering plants in the family Bromeliaceae, subfamily Bromelioideae. The genus name is from the Greek cryptos (hidden) and anthos (flower). The genus formerly had two recognized subgenera: the type subgenus and subgenus Hoplocryptanthus Mez which has been raised to the separate genus Hoplocryptanthus. All species of this genus are endemic to Brazil. The common name for any Cryptanthus is "Earth star".

## Former species

A major revision of Cryptanthus in 2017 based on both morphological and molecular characters elevated a former subgenus to the genus Hoplocryptanthus and created two new genera, Forzzaea and Rokautskyia, transferring many former Cryptanthus species to these three genera.
