| Term | Synonyms | Category | Limitation | Definition |
|---|---|---|---|---|
| floating 2 | location | At or upon the surface of water. | ||
| floccose | < tufted | pubescence | Bearing tufts of soft, fine, capillate trichomes that rub off easily. | |
| …floral | = …flowered | architecture | inflorescence | Having the number of flowers indicated by the prefix; as in bifloral, multifloral, oligofloral, unifloral. |
| floral | insertion | Upon, within, or associated with the flowers. | ||
| floral | position | Upon, within, or associated with the flowers. | ||
| floral cup 1 (broad sense) | = floral tube, hypanthium (broad sense) | STRUCTURE | A complex structure comprising fused portions of the perianth and/or androecium of a flower, sometimes also including receptacular tissue; surrounding and wholly, partly, or not at all adnate to the gynoecium; subdivided morphologically into casing, collar and/or neck; sometimes bearing free distal portions of the constituent structures. | |
| floral cup 2 (strict sense) | = hypanthium (strict sense) | STRUCTURE | A marginal protrusion from or enlargement of the receptacle (torus) of a flower, encircling and wholly, partly or not at all adnate to the gynoecium, bearing the perianth and androecium. | |
| floral tube | = floral cup (broad sense), hypanthium (broad sense) | STRUCTURE | A complex structure comprising fused portions of the perianth and/or androecium of a flower, sometimes also including receptacular tissue; surrounding and wholly, partly, or not at all adnate to the gynoecium; subdivided morphologically into casing, collar and/or neck; sometimes bearing free distal portions of the constituent structures. | |
| floret | STRUCTURE | A very small, structurally specialized flower, especially when occurring in capitulum (head; Asteraceae), or in a spikelet (Poaceae), where it includes the immediately subtending bracts (lemma and palea). | ||
| floricane | STRUCTURE | A biennial or perennial stem after it has begun flowering, when that does not occur until at least its second season of growth; applied especially to the stems of brambles (Rubus spp.). | ||
| floriferous | = flower-bearing | architecture | plant, structure | Bearing flowers. |
| flower | STRUCTURE | A functionally integrated, complex structure comprising sets of sporophytic and/or associated sterile structures disposed in standard sequence along a common axis; consisting of one or more constituent members each of, in ascending (proximal to distal) order of insertion, perianth (tepals, or else sepals and/or petals), androecium (stamens, staminodes and/or other associated structures), and/or gynoecium (pistils and/or other associated structures), the foregoing all borne laterally from the distal portion (receptacle) of the axis; depending upon the combination of structures present, may be bisexual, staminate only, pistillate only, or sterile; characteristic of and unique to the Magnoliophyta (Angiospermae). When a fertile androecium and gynoecium are both present a flower is termed perfect. When perfect and also with calyx and corolla both present, a flower is termed complete. Both terms are somewhat archaic and of limited descriptive value. | ||
| flower-bearing | = floriferous | architecture | plant, structure | Bearing flowers. |
| …flowered | = …floral | architecture | inflorescence | Having the number of flowers indicated by the prefix; as in few-flowered, single-flowered, three-flowered. |
| flush | prominence | Even with the surrounding surface, neither higher nor lower than its general level. | ||
| fluted | solid shape | Having rounded to angular longitudinal grooves. | ||
| foliaceous | = leaf-like | architecture | structure | Resembling a leaf in shape, texture and color. |
| foliar | insertion | Upon or otherwise directly associated with the leaves. | ||
| foliar | position | Upon or otherwise directly associated with the leaves. | ||
| …foliate | = …leaved | architecture | plant, stem | Having (only) the number of leaves indicated by the prefix; as in hexafoliate, trifoliate. |
| foliate | = leaf-bearing | architecture | plant, stem | Bearing leaves. |
| …foliolate | = …leafleted | architecture | foliaceous structure | Compound with one order of the number of leaflets indicated by the prefix, arranged either pinnately or palmately; as in bifoliolate, pentafoliolate, trifoliolate. See also conjugate, one-leafleted (single-leafleted, unifoliolate), unijugate. |
| foliose 1 | architecture | stem | Bearing many leaves. | |
| foliose 2 | architecture | thallus | Having leaf-like lobes; in Hepaticae. | |
| follicetum pl. folliceta | STRUCTURE | An aggregate of follicles produced from a single flower with multiple simple pistils. |
