Abstract

Bromeliaceae and Orchidaceae are well represented in the New World tropics where both families have generated numerous xeric species including some that are well adapted to exploit the driest, most nutrient-deficient portions ofthe epiphytic biotope. Two very common epiphytes which grow in a variety of forest communities, including some relatively infertile ones in southwestern Florida, are the butterfly orchid Encyclia tampensis (Lindl.) Small and the bromeliad Tillandsia circinnata Schlecht. Although these two epiphytes are ecologically equivalent in that they share the same hosts in many of the same forest communities, E. tampensis depends, as do all epiphytic orchids, on its modified root system for moisture and salt absorption. Tillandsia circinnata, like other specialized epiphytic members of subfamily Tillandsioideae, produces a much reduced root system which is specialized for holdfast. Moisture and mineral nutrients enter the plant through the trichomed shoot surface.
