| Term | Synonyms | Category | Limitation | Definition |
|---|---|---|---|---|
| fissured | relief | bark | Split or cracked vertically, diagonally, and/or horizontally in a regular or irregular pattern, the fissures not encircling the stem individually. | |
| fistulose | solid shape | Basically tubular with closed ends. | ||
| five-… | = penta… | prefix | Indicating presence of or constitution by five entities of the type denoted by the term's stem; as in five-grooved, five-stamened, five-tepaled. | |
| fixation | CHARACTER | Mode of attachment to a supporting structure. | ||
| fixed | fixation | Attached to the bearing structure in a manner allowing no significant rotation or declination in relation to it. | ||
| flabellate | = fan-shaped, flabelliform | solid shape | Strongly compressed, broadest near the apex and attenuate to a narrow base, plaited longitudinally, the alternating folds radiating from the base, the whole basically triangular in broad aspect; like a partially expanded folding fan. | |
| flabelliform | = fan-shaped, flabellate | solid shape | Strongly compressed, broadest near the apex and attenuate to a narrow base, plaited longitudinally, the alternating folds radiating from the base, the whole basically triangular in broad aspect; like a partially expanded folding fan. | |
| flabelliramous | = polytomous | architecture | axis | Branching by division of the apical meristem to produce more than three equal derivatives. |
| flaccid | texture | Limp, sometimes appearing withered or shrunken. See also tumid (swollen, turgid). | ||
| flagelliform | = whip-like | solid shape | Very slender, terete, generally straight, and apparently supple. | |
| flagellum pl. flagella | STRUCTURE | A very slender whip-like structure that extends from the main body of an antherozoid and, by active undulation, propels the cell through a liquid medium. | ||
| flange | STRUCTURE | A relatively broad, circumferential rim or ridge that protrudes laterally. | ||
| flanged | plane shape | Having a relatively broad circumferential rim or ridge that protrudes laterally. | ||
| flanged | solid shape | Having a relatively broad circumferential rim or ridge that protrudes laterally. | ||
| flask-shaped | = ampulliform, lageniform | solid shape | Generally circular in cross-section, broadest at or below the middle, approximately globose below that and constricted above to a relatively narrow neck; like a flask. | |
| flattened | > complanate, compressed, depressed, obcompressed | solid shape | Convex overall but with one or more sides or ends distinctly deviating toward plane, as though pressed or squeezed there. | |
| fleeting | = fugacious | duration | structure | Wilting or withering very shortly after emergence, soon becoming inconspicuous and falling away or disintegrating. |
| flesh | STRUCTURE | Tissue that is fairly firm and dense, juicy or at least moist, and easily cut. | ||
| fleshy | = carnose, sarcous | texture | Fairly firm and dense, juicy or at least moist, and easily cut. | |
| fleshy-stemmed | = sarcocaulous | texture | plant | Having main stems that are fleshy (carnose, sarcous). |
| flexed | = bent | solid shape | Having an abrupt bend at some point along its length. See also declinate (inclinate), geniculate (kneed), inflexed, reflexed. | |
| flexible | = pliable, pliant, supple | texture | Able to bend over its length and/or breadth without structural disruption. | |
| flexuose | course | See flexuous. | ||
| flexuous var. flexuose | = zig-zag | course | Having alternating angular bends to either side, more or less straight between the bends. | |
| floating 1 | habit | plant | Buoyant and growing entirely at or near the surface of water, not rooted in any substrate. |
