STRUCTURE |
|
The lower (proximal) or sometimes solitary small bract inserted at the base of a grass (Poaceae) spikelet, the second glume, when present, inserted immediately above (distal to) it. |
fissure |
|
FEATURE |
|
A relatively narrow, split or crack in the outer tissue(s) of a structure. |

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. |
