Description en: Genus of over 400 species of epiphytic, terrestrial, or rock-dwelling, evergreen perennials (bromeliads) from scrub and woodland in S. USA, the West Indies, and Central and South America. The entire, often scaly leaves are strap-shaped to narrowly triangular to linear, some-times tapering to fine threads; they are mainly borne in rosettes, with a few along the slender stems, and sometimes have prominent sheaths. Most species have tubular to funnel-shaped flowers, each with 3 sepals and 3 petals, often with spreading terminal lobes; they are borne among usually colourful floral bracts, generally opening in daytime in spring or autumn. The flowers may be solitary but are usually in 2 or more opposite rows, forming small, dense racemes or spikes, which are sometimes grouped into compound inflorescences; the flowers are borne mainly at the ends of scapes that have sometimes dense or colourful bracts. Where temperatures fall below 7°C (45°F), grow in a temperate greenhouse or conservatory, or as houseplants. In warmer areas, grow the epiphytic species on a tree; the rock-dwelling and terrestrial species may also be grown in a rock garden, on bark or tree branches placed on the ground, or beneath trees or shrubs.
