Canistropsis derives its name from the genus Canistrum and the Greek "opsis" meaning resembling. There are only 11 species, all originally found in Brazil. Some of the small bromeliads that previously were in Nidularium have been reclassified as Canistropsis. They were called Nidularium citrinum at one time. Visually, Nidularium petals are tightly fused into an upright tube and in Canistropsis they are spreading and unfused. Also, Canistropsis are all pretty stoloniferous, whereas Nidulariums aren't. These are shade-loving plants, very easy to grow, and multiply readily. Give them the same care you would Vriesea and Guzmania.
