gynoecium pl. gynoecia var. gynaecium |
|
STRUCTURE |
|
The pistil(s) of a single flower together with any ontogenetically equivalent or subordinate structures present, taken collectively; the total female (ovule-producing) structural complement of a single flower. It may include one to many pistils, each simple or compound. |
|
gynomonoecious |
|
reproduction |
taxon |
Having all plants with both bisexual flowers and pistillate ones. |
|
gynophore |
= hypogynium; < stalk, stipe (broad sense, not recommended) |
STRUCTURE |
|
The basal portion of an ovary when constricted and stalk-like above the level of perianth insertion, bearing the main body of the pistil at its summit. |
|
gynostegium pl. gynostegia |
< corona |
STRUCTURE |
|
An androecial corona, typically consisting of distinct hood- and/or horn-shaped enations that rise above the anthers; esp. in Asclepiadaceae. |
|
gynostemium pl. gynostemia |
= column, gynandrium |
STRUCTURE |
|
A central floral structure consisting of the partly to wholly fused (connate and adnate) androecium and gynoecium; esp. in Orchidaceae. |
|
habit |
|
CHARACTER |
|
General appearance and/or function, usually including explicit or implicit reference to one or more aspects of habitat or other features of the external environment; a logically imprecise traditional category of terms that overlaps conceptually with architecture, arrangement, duration, insertion, location, orientation, position, shape, and texture. |
|
haft |
|
STRUCTURE |
|
The narrow portion of a structure that is notably constricted. |
|
hair |
= capillus; > glochid, glochidium; < cilium, trichome |
STRUCTURE |
|
A hair-like trichome. |
|
hair-like |
= capillary, capillate |
solid shape |
|
Finely filiform; resembling a hair. |
|
halberd-head-shaped 1 |
= hastate |
base |
laminar structure |
Having two generally triangular lobes, one to either side, oriented more or less perpendicular to the central axis. |
|
halberd-head-shaped 2 |
= hastate |
plane shape |
|
Basically triangular with an acute apex and two large, widely divergent basal lobes, each generally triangular and distally acute; like the stylized outline of the broad lateral face of a halberd head. |
|
half-inferior |
= subinferior |
position |
ovary |
Having its proximal portion enclosed by a floral tube casing, the more distal portions of the perianth and/or androecium thus arising between its base and apex. |
|
half-obterete |
= semiobterete |
solid shape |
|
Inversely half-terete; obterete but flattened on one side. |
|
half-terete |
= semiterete |
solid shape |
|
Terete but flattened on one side. |
|
hamate |
= hooked, uncinate |
apex |
|
Having a recurved terminal portion that resembles a hook. |
|
hanging |
= pendent, pendulous |
orientation |
stalked structure |
Having the stalk strongly recurved from its base, the main body oriented downward. See also nodding (cernuous, nutant). |
|
hapaxanthic |
= monocarpic |
reproduction |
plant |
Normally reproducing sexually only once, then promptly senescent. |
|
haplocheilic |
= simple-lipped |
architecture |
stomate |
Having subsidiary cells not derived from the primary stoma mother cell and thus not immediately related ontogenetically to the guard cells. |
|
haplomorphic |
|
architecture |
flower |
Having the members of each set of basic floral structures numerous and spirally arranged, the flower hemispheric to conoidal overall. |
|
hard |
= indurate(d) |
texture |
|
Yielding only under strong pressure; not deformable without internal structural disruption. See also callose (callous), hard-coated (corticate), hard-stemmed (sclerocaulous). |
|
hard-coated |
= corticate |
texture |
|
Having a hard exterior layer and a distinct, softer interior. |
|
hard-stemmed |
= sclerocaulous |
texture |
plant |
Having hard, relatively dry, but essentially herbaceous main stems that contain a significant proportion of sclerotic tissue or fibers. |
|
hastate 1 |
= halberd-head-shaped |
base |
laminar structure |
Having two generally triangular lobes, one to either side, oriented more or less perpendicular to the central axis. |
|
hastate 2 |
= halberd-head-shaped |
plane shape |
|
Basically triangular with an acute apex and two large, widely divergent basal lobes, each generally triangular and distally acute; like the stylized outline of the broad lateral face of a halberd head. |
|
hastula pl. hastulae, hastulas |
= ligule misapplied |
STRUCTURE |
|
An outgrowth or enation from the petiole apex at its junction with the adaxial surface of a palmate leaf blade; often woody in texture; variously shaped, its adaxial outline usually resembling an inverted V or U, or a semicircle with the opening proximal; esp. in Arecaceae (Palmae). |
