Tillandsioideae is a subfamily of plants in the bromeliad family Bromeliaceae. This group contains the fewest genera (9) but the greatest number of species (1,277). Most are epiphytic or lithophytic, growing in trees or on rocks where they absorb water and nutrients from the air. Spanish moss of the Tillandsia genus is a well-known variety. Bromeliads in the genera Guzmania and Vriesea are the more commonly cultivated members of this subfamily.

Description

Nearly all bromeliads have specialized cell groups called trichomes which form scales on the foliage. The trichomes occurring on Tillandsioideae may cover the plants so completely that they appear grey or white, like Spanish moss. In addition to absorbing nutrients, the trichomes may serve to insulate the plant from freezing weather.

Plants in this group have smooth or entire leaf margins, unusual color and markings, with many producing fragrant flowers. All their leaves are spineless (unarmed) and their fruit is a dry capsule containing winged seeds which are usually dispersed by breezes. Feathery seed plumes help them to adhere to a suitable epiphytic surface for germination. This subfamily is probably the most derived with special adaptations for survival in very dry conditions, with many described as xerophytes.
