Flower or leaf with continuous margin, without teeth or divisions.
Epiphyte
Plant that grows supported upon another, without being parasitic. Epiphytes use the host plant only as support, without directly taking nourishment. Several bromeliads, for example, are epiphytes.
Eremurus
Also known as foxtail lilies or desert candles
Escarp or embankment
Sloped and plane surface like those in the sides of roads, obtained by excavating terrain, or in a dumpsite.
Evergreen
Plants that keep their leaves all year long. (Also see Deciduous.)
Tubercle: Thick and fleshy stem or root that acts as a storage organ. Some plants with tuberous roots can lose their leaves and stem in autumn, as the tubercle stores nourishment for new growth during the next spring. Example. Begonia tuberosa. Sometimes tubercles are produced in stalks. The tubercle is a globular structure provided with a reserve of nutrients; the potato is a typical tubercle, but not all tubercles are subterranean. (Compare Bulb, Corm, and Rhizome).
