BOT 360F - Families of Vascular Plants

BROMELIACEAE: Tillandsioideae
Tillandsia spp.

Tillandsia comprises about 380 species of epiphytes. Most grow as rosette plants, but T. usneoides has pendent stems that hang from tree branches or overhead wires. The basal portions of these stems are attached to the substrate and eventually die leaving behind a strand of sclerencyma. Nutrients and water are absorbed on all of the scale-covered surfaces of the plant directly from water dripping over it.
