| Term | Synonyms | Category | Limitation | Definition |
|---|---|---|---|---|
| exudation | CHARACTER | Discharged substance, as to type. | ||
| eyespotted | = ocellate | coloration | Having a more or less circular area that differes in hue and/or intensity from the remainder of the structure; esp. a corolla with such an area at its center. | |
| face | FEATURE | A relatively large, flat or shallowly curved portion of the external surface of a three-dimensional structure, bounded by more or less distinct topological discontinuities. | ||
| …faced | solid shape | Having relatively large, flat or shallowly curved portions of the external surface that are bounded by more or less distinct angular discontinuities in that surface, of the number indicated by the prefix; as in three-faced. | ||
| faceted | solid shape | Having numerous, relatively small, flat or shallowly curved portions of the external surface that are bounded by more or less distinct angular discontinuities in that surface. | ||
| falcate 1 | = sickle-shaped | plane shape | Elongate and laterally arcuate with the lateral edges more or less concentric, the degree of curvature decreasing distally or not; like the outline of the face of a sickle blade. | |
| falcate 2 | = sickle-shaped | solid shape | Elongate, strongly compressed, and arcuate in the plane of compression, the two faces more or less plane and parallel, the degree of curvature decreasing distally or not; like a sickle blade. | |
| false | derivation | indusium | Constituting a marginal fold of the lamina as a whole and not a distinct enation from the epidermis. | |
| fan-shaped | = flabellate, 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. | |
| farinaceous 1 | = mealy; < crumbling, fatiscent | texture | Of minute, relatively stout trichomes that are collectively meal- or flour-like and easily detached. See also farinose. | |
| farinaceous 2 | < mealy | pubescence | Loose, dry, and disintegrating in finely granular pieces like meal or flour. | |
| farina pl. farinae, farinas | SUBSTANCE | A dry, meal- or flour-like covering. | ||
| farinose | < mealy | pubescence | Bearing minute, relatively stout trichomes, collectively meal- or flour-like (farinaceous) and easily detached. See also farinaceous. | |
| fasciate(d) | fusion | equivalent structures | Abnormally proliferated in size and/or number and more or less connate, the result often monstrous. | |
| fascicle | = bundle (not recommended) | nominative | inflorescence | A cluster of pedicellate flowers that are inserted very close together and little if at all divergent from one another, the whole sessile or subsessile. |
| fascicled 1 | = bundled (not recommended), fasciculate | architecture | inflorescence | Comprising one or more fascicles. |
| fascicled 2 | = bundled (not recommended), fasciculate | arrangement | Disposed in one or more fascicles, the members of each inserted close together and only slightly if at all divergent from one another. | |
| fasciculate 1 | = bundled (not recommended), fascicled | architecture | inflorescence | Comprising one or more fascicles. |
| fasciculate 2 | = bundled (not recommended), fascicled | arrangement | Disposed in one or more fascicles, the members of each inserted close together and only slightly if at all divergent from one another. | |
| fastigiate | arrangement | branches | Closely parallel to one another and to the axis of origin over most of their lengths. | |
| fatiscent | = crumbling; > farinaceous, mealy | texture | Easily disintegrating in relatively small pieces, either spontaneously or under pressure. | |
| feather-shaped | = plumose | solid shape | Having a slender central axis bearing two opposite ranks of numerous, closely proximate, ascending, very slender branches or appendages; resembling the generalized form of a feather. | |
| felted | > panniform, pannose | pubescence | Of or bearing closely intertwined, capillate trichomes that form a dense, felt-like mat. | |
| female | = feminine | reproduction | Of the sex that produces megaspores and ova. | |
| female cone | = macrostrobilus (not recommended), megastrobilus | STRUCTURE | A cone (strobilus) whose fertile organs are all megasporophylls. |
