Tillandsioideae is a subfamily of plants in the bromeliad family Bromeliaceae. This subfamily contains the greatest number of species (about 1,400). Most are epiphytic or lithophytic, growing in trees or on rocks where they absorb water and nutrients from the air. Spanish moss of the genus Tillandsia is a well-known species.
Brocchinia reducta, like many other bromeliads, forms a water-storing cup with its tightly overlapping, bright yellow and green leaves, creating a cylinder when growing outdoors called a rosette. [7] The leaves surrounding the cup of B. reducta are coated with a very loose yet thick wax coat. [ 5 ]
Tillandsia caput-medusae is a species of flowering plant in the bromeliad family, Bromeliaceae, subfamily Tillandsioideae. Common names include octopus plant and medusa's head. An epiphyte native to Central America and Mexico, T. caput-medusae is a commonly cultivated bromeliad species. The thick, channeled, tapering and twisting leaves are up ...
Some of the species, like the majority of Bromeliaceae, grow as funnel bromeliads, with a compressed stem axis. The leaves are then close together in rosettes, and cover the lower areas of the leaves, forming a funnel for collecting water. [2] These leaf rosettes, a common physical characteristic in Tillandsia species, collect nutrients and water.
Bromeliads with leaf vases can capture water and nutrients in the absence of a well-developed root system. [11] Many bromeliads also use crassulacean acid metabolism (CAM) photosynthesis to create sugars. This adaptation allows bromeliads in hot or dry climates to open their stomata at night rather than during the day, which reduces water loss ...
Bromelioideae is a subfamily of the bromeliads (Bromeliaceae). This subfamily is the most diverse in the family, represented by the greatest number of genera with about 40. [ 1 ] Most of the plants in this group are epiphytes , though some have evolved in, or will adapt to, terrestrial conditions.
Soaking the seeds of Bromelia laciniosa in acetone for 60 minutes is an effective treatment that increases vigor and germination. [6] The roots of Bromelia laciniosa are thin to facilitate water absorption and reach over a meter deep and 8 inches in diameter; because of this, bromeliads generally have efficient nitrogen uptake. [3]
Tillandsia recurvata derives mainly physical support and not nutrition from its host; it photosynthesizes its own food, absorbing water that collects on its leaves. [4] It obtains nitrogen from bacteria, and other minerals largely from blown dust. [ 5 ]
