casing |
|
STRUCTURE |
|
The portion (if any) of a floral tube that is adnate to the gynoecium. See also collar, neck. |
|
diplostemonous |
|
architecture |
flower, androecium |
Having the stamens dicyclic, the proximal whorl with members directly above the sepals, the distal whorl with members directly above the petals. See also obdiplostemonous. |
|
amphibious |
|
habit |
plant |
Able to live in either aquatic or terrestrial habitats; e.g., adapted to periodic inundation on floodplains. |
|
antisepalous |
|
position |
equivalent floral structures |
Each inserted directly above or below a sepal. In place of this term, the phrase "opposite the sepals" is often used, but that contradicts the sense of opposite as otherwise employed (arrangement of lateral structures along an axis) and should be avoided. |
|
…ciliate |
|
architecture |
|
Bearing the number of cilia indicated by the prefix. |
|
antrorse |
|
orientation |
|
Directed forward or upward, toward the distal end of the context of reference, parallel or at an acute angle to the bearing structure. |
|
ciliate |
|
margin |
|
Having fine, hair-like trichomes (cilia) oriented in the general plane of the structure. |
|
supramedial |
|
position |
|
Just above the middle of the structure in point. |
|
…merous |
|
architecture |
compound or compound-complex structure |
Having the number of equivalent component parts indicated by the prefix (e.g., petals in a corolla), or having different component sets of equivalent parts of that number in each set (e.g., calyx and corolla in a perianth); as in monomerous, oligomerous, polymerous, tetramerous, trimerous. |
|
caespitose |
|
habit |
|
See cespitose. |
|
inflated |
|
solid shape |
|
Relatively thin-walled with an essentially empty interior largely enclosed by the walls, which are convex overall and appear taut, as though from internal pressure. See also swollen (turgid, tumid), which is not clearly distinct in its application. |
|
anisopetalous |
|
architecture |
flower, perianth, corolla |
Having petals unequal in size and/or shape. |
|
areolate |
|
relief |
|
Having numerous, small, irregularly disposed, transversely angular, shallow depressions or low protrusions overall. |
|
false |
|
derivation |
indusium |
Constituting a marginal fold of the lamina as a whole and not a distinct enation from the epidermis. |
|
prophyllar |
|
insertion |
|
Upon or otherwise directly associated with the prophylls (bracteoles, bractlets). |
|
motile |
|
habit |
|
Able to translocate by intrinsic means, as by flagellar propulsion. |
|
trilete |
|
architecture |
spore |
Having a triradiate tetrad scar. |
|
free-central |
|
placentation |
|
Upon the free axial column of a compound, unilocular ovary. |
|
porous |
|
porosity |
|
Having vessels present. |
|
rachis 2 var. rhachis |
|
STRUCTURE |
|
A main or first-order axis of an inflorescence. |
|
nucellus pl. nucelli |
|
STRUCTURE |
|
The distinct, genetically diploid tissue layer immediately surrounding the embryo sac of an ovule; often considered equivalent to a megasporangium wall. |
|
ribbed 2 |
|
solid shape |
|
Having two or more prominent, elongate, relatively narrow, essentially parallel protrusions that extend over all or most of its length or circumference. |
|
valvate 4 |
|
dehiscence |
fruit |
With longitudinal segments of the wall (valves) separating partly or wholly from one another, spreading outward from the base or apex, and sometimes falling away. |
|
elastic |
|
texture |
|
Resiliently deformable with no loss of structural integrity. |
|
obvolute 1 |
|
arrangement |
cotyledons |
Having each cotyledon folded inward longitudinally, the two facing one another with their edges overlapping alternately (each enveloping one side or the other). |
