| Name | Structure/ Category | Description |
|---|---|---|
| Edged | [Leaf lower surface, Leaf upper surface] {color variegation} | One color is surrounded by a very narrow rim of another. |
| Ellipsoid | [Buds] {shape} , [Seed cones] {shape before opening, shape when open} | Widest near the middle, with convex sides tapering equally toward rounded ends, and rounded in cross section; elliptic or oval-shaped in outline. |
| Ellipsoid-cylindric | [Buds] {shape} , [Seed cones] {shape before opening, shape when open} | Intermediate in shape between ellipsoid and cylindric. |
| Elliptic | [Leaflets, Leaves, Petals, Phyllaries, Sepals] {shape} | Widest near the middle, with convex sides tapering equally toward both ends |
| Emarginate | [Leaf apices, Leaflet apices, Petal apices, Phyllary apices, Sepal apices] {shape} | With a notch at the apex. |
| Endemic | restricted to or native to a particular area or region INDIGENOUS -- used of kinds of organisms | |
| Ensiform | [Leaflets, Leaves] {shape} | Long and moderately slender, flat in cross section, gradually tapering to a pointed apex; sword-shaped; as an Iris leaf. |
| Entire | [Leaf margins, Leaflet margins, Petal margins, Phyllary margins, Sepal margins] {form} | With relatively smooth margins that lack teeth, spines or other projections (the margins may be lobed); with a continuous margin. |
| Epidermal | of, relating to, or arising from the epidermis [which is] a layer of primary tissue in higher plants that is commonly one cell thick, often cutinized on its outer surface, and continuous in young plants except over the stomata, that provides protecti on to underlying parts against mechanical injury and desiccation, and that is largely replaced (as by periderm or exodermis) in older plants except on leaves and herbaceous stems | |
| Epidermis | The outermost layer of cells of leaves, young stems and roots. |
