| Forked | Same as furcate. | |
| Fornicate | Arched. Same as recurved. |  |

| Fractiflex | Zigzagged; referring to a structure that is bent alternately in opposite directions much more sharply than is implied by the term flexuous. | |
| Free | Same as distinct. | |
| Frondose | Leafy; used to describe inflorescences bearing numerous, leaflike bracts, a condition especially common in the Rubiaceae. | |
| Fugacious | Falling off early. Same as caducous. |  |
| Fulvous | Dull yellowish brown. | |
| Furcate | Forked, separating into two divisions. | |
| Furfuraceous | Scurfy or flaky. | |
| Fusiform | A solid shape narrowed toward both ends from a swollen middle. | |
| Galea (plural =galeae) (galeate) | A helmet-or hood-shaped, as the upper lip of some bilabiate corollas (possessing galeae). | |
| Geniculate | Abruptly bent like a flexed knee. |  |
| Gibbous | Pouched or swollen on one side. |  |
| Glabrate | Becoming glabrous. | |
| Glabrescent | Becoming glabrous or nearly glabrous. | |
| Glabrous | Smooth, devoid of trichomes (hairs). | |
| Gland | A secretory structure such as a floral or extrafloral nectary; a glandlike body whether it is secretory or not; e.g., the body connecting, via translators, the two pollinia of Apocynaceae subfamily Asclepiadoideae. |  |
| Glaucous | Covered with a whitish substance that can be rubbed off. | |
| Globose | Referring to a spherical solid shape. |  |
| Glomerate | Referring to a structure, such as an inflorescence, composed of very densely clustered units; e.g., flowers. | |
| Granular | Referring to a surface covered my minute, grain-like bodies. | |
| Granulate (granulose) | Appearing as if covered by very small grains; minutely or finely mealy. | |
| Hair | See trichome which is used more correctly for plants. | |
| Hastate | In the shape of an arrowhead but with the basal lobes spreading at more or less right angles to the long axis. |  |
| Hetero- | A prefix meaning different or other. | |
| Heteroblastic | Referring to a plant with juvenile forms that are morphologically distinct from adult forms; often used to describe leaves changing from compound to simple as the plant passes from juvenile to adult. | |
| Heteromorphic | Referring to structures or organs within a species or individual that differ in form or size; e.g., the simple juvenile and pinnately compound leaves of Syagrus inajai (Arecaceae). Compare with dimorphic and monomorphic. |  |
