|
adventitious |
|
derivation |
|
Arising more or less unpredictably from an organ, tissue, or site that is an unusual, abnormal, or atypical origin for structures of its type. |
|
involucral |
|
derivation |
aril |
Produced from or a modification of a persistent involucre investing the seed. |
|
centrifugal |
|
development |
|
Proceeding away from the center, thus more advanced centrally than peripherally within a given frame of reference. |
|
centripetal |
|
development |
|
Proceeding toward the center, thus more advanced peripherally than centrally within a given frame of reference. |
|
determinate |
|
development |
|
Having the terminal (central, apical, or distal) portion differentiating first and the lateral (peripheral, basal, or proximal) portions later, development thus proceeding sequentially downward or outward, growth of the whole thereby organizationally limited. |
|
acropetal |
|
development |
|
Proceeding toward the apex, thus more advanced basally or proximally than apically or distally within a given frame of reference. |
|
epinastic |
|
development |
laminar structure |
Having the adaxial surface differentiating and growing faster than the abaxial surface, thus, until maturity, development of the former more advanced than that of the latter at any given time and the structure as a whole revolute or recurved. |
|
indeterminate |
|
development |
|
Having the lateral (peripheral, basal, or proximal) portions differentiating first and the terminal (central, apical, or distal) portion later, development thus proceeding sequentially upward or inward. |
|
basipetal |
|
development |
|
Proceeding toward the base, thus more advanced apically or distally than basally or proximally within a given frame of reference. |
|
hyponastic |
|
development |
laminar structure |
Having the abaxial surface differentiating and growing faster than the adaxial surface, thus, until maturity, development of the former more advanced than the latter at any given time and the structure as a whole involute or incurved. |
|
marcescent |
|
duration |
structure |
Persistent in a distinctly withered condition. |
|
fleeting |
= fugacious |
duration |
structure |
Wilting or withering very shortly after emergence, soon becoming inconspicuous and falling away or disintegrating. |
|
ephemeral |
|
duration |
plant |
Annual with a very short life span; germinating, growing, reproducing, and dying within a brief period of favorable conditions, the entire cycle being completed within a few weeks. |
|
persistent |
|
duration |
structure |
Remaining attached and conspicuous until the bearing structure reaches maturity. |
|
pliestesial |
|
duration |
plant |
Perennial and monocarpic, living several to many years before reproducing sexually, dying promptly thereafter. |
|
deciduous 1 |
|
duration |
structure |
Separating and falling away from the bearing axis, organ or plant prior to senescence of the latter, usually by developing an anatomically distinct, transverse, basal zone of cells (abcission layer), where separation occurs. See also seasonally deciduous. |
|
accrescent |
|
duration |
structure |
Increasing further in size after the bearing structure has become functionally mature; esp. a calyx after anthesis. |
|
biennial 1 |
|
duration |
plant, stem |
Normally living two years; germinating or forming and growing vegetatively during one cycle of seasons, then reproducing sexually and dying during the following one. |
|
perennate |
|
duration |
structure |
Persisting in a functional state through the entire growing season. |
|
perennial 1 |
|
duration |
plant |
Normally living more than two years, with no definite limit to its life span. |
|
caducous |
|
duration |
structure |
Deciduous upon or immediately after emergence, with little or no evident senescence beforehand. |
|
annual 1 |
|
duration |
plant, stem |
Normally living one year or less; growing, reproducing, and dying within one cycle of seasons. |
|
fugacious |
= fleeting |
duration |
structure |
Wilting or withering very shortly after emergence, soon becoming inconspicuous and falling away or disintegrating. |
|
partial |
|
extent |
|
Not reaching fully from the ovary wall or pericarp to the center of the ovary or fruit and/or from the apex to the base of its interior, thus not completely separating adjacent locules, which are recognized and delimited by extrapolating from the incomplete septal boundary(ies), the ovary or fruit nonetheless effectively unilocular. |
|
full |
|
extent |
|
Reaching from the ovary wall or pericarp to the center of the ovary or fruit and from the apex to the base of its interior, thus separating adjacent locules completely. |
