corolla pl. corollae, corollas |
|
STRUCTURE |
|
Collectively, the petals of a flower, whether distinct or connate; the inner or distal envelope of a differentiated perianth, whether the other envelope (calyx) is actually present or is deemed to be absent due to evolutionary reduction. |
neuter |
|
architecture |
flower, floret |
Lacking both stamens and pistils. |
cymulose |
|
architecture |
inflorescence |
Comprising one or more cymules. |
syncarpous |
|
architecture |
flower, gynoecium |
Having one or more compound pistils. |
andropetalous 2 |
|
derivation |
flower, perianth, corolla |
Having some or all petals derived from stamens. |
suprabasal |
|
insertion |
|
Just above the base of the structure in point. |
diplecolobal |
|
arrangement |
cotyledons |
Incumbent but with the cotyledons folded together twice or more, the folds transverse. |
dyad |
|
STRUCTURE |
|
A pair of coherent pollen grains shed as a unit. |
panicle |
|
nominative |
inflorescence |
A compound (branched) raceme, the elongate main axis either determinate or indeterminate, its lateral branches racemose. |
umbellet |
|
nominative |
inflorescence |
A single set of pedicellate flowers in a compound umbel. |
terrestrial |
|
habit |
plant |
Growing upon the ground, usually rooted in it. |
basipetal |
|
development |
|
Proceeding toward the base, thus more advanced apically or distally than basally or proximally within a given frame of reference. |
epiphyllous |
|
insertion |
|
Upon the leaves, or partially adnate thereto and apparently arising therefrom. |
acroramous |
|
architecture |
axis |
Branching at or near the apex. |
branchlet |
|
STRUCTURE |
|
A branch of the highest or ultimate order. |
pollen |
|
STRUCTURE |
|
Collectively, the spores or grains produced within the thecae of anthers, each containing a very small microgametophyte (or its evolutionary homologue); serving as disseminules from which microgametes are released after transport to a receptive micropylar pollen droplet (in Pinophyta) or stigma (in Magnoliophyta) by a variety of vectors, notably wind, water, insects, bats, and birds. |
wiry |
|
architecture |
axis |
Relatively very narrow and elongate, tough, and resiliently flexible. |
floating 1 |
|
habit |
plant |
Buoyant and growing entirely at or near the surface of water, not rooted in any substrate. |
pseudobulb |
|
STRUCTURE |
|
An enlarged internode of an aboveground stem, storing water and photosynthate, resembling a bulb; esp. in Orchidaceae. |
wall (fruit, ovary, pollen, spore) |
|
STRUCTURE |
|
The exterior layer of tissue(s) enclosing anatomically distinct interior tissues and sometimes fluid and/or one or more cavities. |
caducous |
|
duration |
structure |
Deciduous upon or immediately after emergence, with little or no evident senescence beforehand. |
canalicular |
|
insertion |
|
Upon or otherwise directly associated with the channel of a petiole or petiolule. |
coating |
|
CHARACTER |
|
Exudate that covers the surface proper. See also indumentum (vesture), pubescence. |
insertion |
|
CHARACTER |
|
Mode or locus of attachment of a structure to some dissimilar bearing structure. The lexicons relating to insertion and position overlap to a great degree, since these two morphological concepts are often inseparable in practice. Also overlaps conceptually with arrangement, habit, orientation, and shape. |
saprophytic |
|
nutrition |
plant |
Heterotrophic and obtaining essential nourishment directly from the decomposing remains of other organisms. |
