| Name | Structure/ Category | Description |
|---|---|---|
| Ovate | [Leaflets, Leaves, Petals, Phyllaries, Sepals] {shape} | Egg-shaped in outline, with the broader end near the base. |
| Ovoid | [Buds] {shape} , [Seed cones] {shape before opening, shape when open} | Rounded in cross section, broadest near a bluntly rounded base and convexly tapering to a narrower rounded tip; egg-shaped. |
| Ovoid-acuminate | [Buds] {shape} | Egg-shaped but with the narrow end concavely tapering to a point. |
| Ovoid-conic | [Buds] {shape} , [Seed cones] {shape before opening, shape when open} | Intermediate in shape between ovoid and conic. |
| Ovoid-cylindric | [Buds] {shape} , [Seed cones] {shape before opening, shape when open} | Intermediate in shape between ovoid and cylindric. |
| Ovoid-ellipsoid | [Buds] {shape} | Intermediate in shape between ovoid and ellipsoid. |
| Ovule | The structure in flowering plants and gymnosperms which when fertilized develops into a seed. | |
| Painted | [Leaf lower surface, Leaf upper surface] {color variegation} | Colors disposed in streaks of unequal intensity. |
| Palea | This is a thin inner scale that encloses the developing seed in a spikelet of grass. The palea resembles a fertile lemma (the outer scale), but it is usually smaller and more difficult to observe. Not all species of grass have a palea as a structure in their flowers. | |
| Palmate | (1) With three or more leaflets, lobes or other structures arising from a common point and diverging from one another; arranged or structured in a hand-like pattern. |
