inflorescence 2 |
|
STRUCTURE |
|
The basic architectural unit of the flower-producing portion of a plant; comprising one or more flowers, their associated supporting axes (peduncles, main axes, branches and pedicels), if any, and the appendages thereto (bracts, bractlets or bracteoles or prophylls, involucres, involucels, and glumes), if any; delimited by the insertion or gradation of a single peduncle, peduncle cluster, pedicel, pedicel cluster, or sessile flower, as the case may be, directly upon or into some proximal vegetative structure not of one of these types; depending upon the type(s) of flowers included, may be bisexual (all flowers bisexual), staminate (all flowers staminate), pistillate (all flowers pistillate), sterile (all flowers sterile), or mixed (two or more types of flowers present); most appropriately described using nominative terms. |
|
…sulcate |
= …colpate, …fossulate, …furrowed, …grooved, …valleculate |
architecture |
|
Having the number of sulci indicated by the prefix; esp. pollen grains; as in monosulcate, polysulcate, 3-sulcate. |

margin |
|
Gently or shallowly sinuate. |
|
beaklet 2 |
= rostellum |
STRUCTURE |
|
A sterile excrescent stigma lobe protruding between the anther and the functional stigma lobes of a column; sometimes forming one or more viscidia at pollinium maturity; esp. in Orchidaceae. |
|
unilateral 3 |
= one-sided |
position |
|
Upon or arising from one side only of the bearing structure. |
|
nectary |
< gland |
STRUCTURE |
|
A multicellular, anatomically distinct structure that produces and exudes nectar. |
|
galeate |
= galeiform, helmet-shaped |
solid shape |
|
Convex overall with a more or less smoothly curved apex, relatively thin-walled and essentially hollow with the interior open to one side below the distal portion; resembling a helmet. See also cucullate (cuculliform, hood-shaped), which overlaps conceptually. |
|
single-veined |
= hyphodromous, one-veined |
venation |
|
Having one median, primary vein and no other venation externally evident. |
|
circumscissile |
|
dehiscence |
|
Splitting transversely through the exterior wall about its entire circumference, the resulting upper cap-like portion falling away. |
|
lanate |
< woolly |
pubescence |
|
Bearing relatively long, moderately stout, intertwined, somewhat matted, capillate trichomes. See also lanulose. |
|
anticlinal |
|
orientation |
|
Perpendicular to some given plane of reference; applied especially to the plane of cell division when it is oriented at right angles to the generalized plane of the structural surface. |
|
fasciculate 2 |
= bundled (not recommended), fascicled |
arrangement |
|
Disposed in one or more fascicles, the members of each inserted close together and only slightly if at all divergent from one another. |
|
sawtooth |
|
STRUCTURE |
|
One of a series of regularly spaced, angular, marginal convexities oriented at an acute angle to the generalized perimeter of a laminar structure. See also sawtoothlet, scallop (crena), scalloplet (crenule), tooth, toothlet. |
