Abruptly enlarged distally to a relatively short, terminal portion that is basically round in transverse section. |
|
ligule 4 |
|
STRUCTURE |
|
The distal, relatively flat portion of the zygomorphic corolla of a ligulate floret, terminating in 5 teeth or lobes; in Asteraceae (Compositae). |
|
valleculate |
= colpate, fossulate, furrowed, grooved, sulcate |
architecture |
|
Having one or more relatively narrow and shallow longitudinal depressions; esp. fruits of Apiaceae (Umbelliferae). |
|
macrosporangium pl. macrosporangia (not recommended) |
= megasporangium |
STRUCTURE |
|
A sporangium that produces megaspores. |
|
bracteole 2 |
= bractlet, prophyll(um); < bract |
STRUCTURE |
|
A second- or higher-order bract within, and subtending some portion of, an aggregate branching structure, especially when subtending a flower. |
|
nodiform |
= gongylodate, gongyloid, knob-shaped, knot-shaped |
solid shape |
|
Approximately globose, the surface convoluted or not, like a knob or knot; usually applied only to structures or components that are relatively small. |
|
chalaza pl. chalazae, chalazas |
|
STRUCTURE |
|
The basal (proximal) portion of an ovule, adjacent to its junction with the funiculus. |
|
parallelodromous |
|
venation |
|
Having two or more primary veins that run more or less parallel to one another over most of the laminar length and converge near the apex. |
|
corniform |
= horn-shaped |
solid shape |
|
Straight or curved and slenderly conic or conoidal, like an animal horn. |
|
pollen sac |
= theca |
STRUCTURE |
|
Any of the one, two or four ontogenetically distinct, pollen-producing sectors (microsporangia) of an anther. In some taxa the walls between pairs of adjacent thecae break down as an anther approaches maturity, the mature anther thus ultimately containing half as many locules as thecae. |
|
raphe |
|
STRUCTURE |
|
That portion of the funicle adnate to the integument of an anatropous ovule; represented by a longitudinal ridge or other discontinuity in the surface and/or color of the testa on one side of the mature seed. |
|
epigeal |
= epigeous |
location |
|
Upon or very near the surface of the ground; esp. of cotyledons following seed germination. |
|
scalloped |
= crenate |
margin |
|
Having regularly alternating, rounded convexities and concavities oriented more or less perpendicular to the generalized perimeter. See also sawtoothed (serrate), small-sawtoothed (serrulate), small-scalloped (crenulate), small-toothed (denticulate), toothed (dentate). |
|
floral |
|
insertion |
|
Upon, within, or associated with the flowers. |
|
soft |
|
texture |
|
Yielding under slight pressure. |
|
stomatiferous |
= stomate-bearing |
architecture |
|
Having stomates present in the epidermis. |
|
floral |
|
position |
|
Upon, within, or associated with the flowers. |
|
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. |
|
stomium pl. stomia |
= stomatal pore |
FEATURE |
|
The opening in the wall of a sporangium, between the lip cells, through which the spores exit; in Psilotophyta, Lycopodiophyta, Equisetophyta, Polypodiophyta. |
|
leaf-opposed |
|
insertion |
|
Nodal and directly opposite the leaf. |
|
muscariform |
= broom-shaped, penicillate |
solid shape |
|
Having a proximal axis that bears a distal cluster of elongate slender branches or appendages, these variously ascending to erect; like a broom. |
