Epiphyte: an organism that is attached to another organism without parasitizing it
Rhizome: a fleshy, horizontal, underground stem
Sori: clusters of sporangia, found especially among the algae and lower vascular plants
Succulent: a plant having thick, fleshy leaves or stems; succulence is usually an adaptation to water or salt stress.
Gymnosperm: plant that has seeds unprotected by an ovary or fruit. Gymnosperms include the conifers, cycads, and ginkgo.
Crassulacean Acid Metabolism (CAM) Photosynthesis: A type of photosynthesis in which CO2 is fixed at night into four-carbon acids; during the day, the stomata close and the carbon is fixed via the Calvin Cycle; CAM helps plants conserve water and is often characteristic of plants that reside in a dry environment.
Vegitative Propagation: A method of plant propagation not through pollination or via seeds or spores but by way of separating new plant individuals that emerge from vegetative parts, such as specialized stems, leaves and roots and allow them to take root and grow. (Biology-online.org)
