EPAPPOSE: Having no tuft of bristles, a feature often found on seeds that are scattered by the wind, such as the seeds of a dandelion.
EPICALYX: A calyx-like involucre of bracts below the true calyx, as in the mallow, or of sepals, as in the potentilla.
EPICARP: The outer skin of fruits.
EPICHILIUM: The terminal part of the lip of some orchids. Also epichil or epichile.
EPICOTYLE: The part of a plant embryo or seedling above the cotyledons.
EPICOTYLEDONARY: Pertaining to the epicotyl; situated above the seed leaves (cotyledons).
EPIDERMIS: The outer, protective tissue of a plant. In succulents, this may bear protective features such as thick, fine hair or bloom.
EPIGEAL: 1. A plant that grows above the surface of the soil, as most plants in the garden do. 2. A cotyledon that is forced above the ground in the process of germination, as in beans, morning glories, and others. 3. Cotyledons that appear above ground. Also epigeous, epigean, epigaean, or epigeic.
EPIGENOUS: Growing on the surface of a leaf or other plant organ (i.e. fungi grow on the surface of leaves, such as mildew).
EPIGYNOUS: Referring to the calyx, corolla, and stamens that appear to be growing from the top of a ovary, but are actually fused to it, as in the cranberry.
EPIPETALOUS: Borne on the petals or the corolla of a flower; applied to stamens and to plants whose stamens are attached to the corolla.
EPIPHYTE: A plant that grows on another (such as on a tree) without being parasitic and obtains nutrients from decaying leaves and other debris and moisture from the air without rooting into the soil. These plants do not obtain nutrients directly from the host plant as do parasites and saprophytes. Many Orchids, Bromeliads, Ferns and some Cacti are epiphytes.
EPISEPALOUS: Growing on or fused with a sepal; applied to stamens.
EPISPERM: The hard external covering of a seed.
EPISPORE: The outer coat or membrane of a spore.
EPIXYLOUS: Growing on wood.
EPRUINOSE: Having no bloom or powdery coating upon the surface of the leaf, stem or other plant part; not pruinose.
