excurrent |
|
architecture |
axis, laminar vein |
Branching laterally such that the initial axis retains its prominence over the length of the structure, the succesive orders of branches relatively smaller. See also deliquescent. |
weeping |
|
architecture |
plant |
Having elongate, flexible, pendent branches. |
heteropolar |
|
architecture |
pollen grain, spore |
Having morphologically evident polarity, the proximal and distal halves dissimilar. |
tree |
|
nominative |
plant |
Perennial, woody, more or less erect, relatively tall, with one or more distinct aboveground portions each with a single, relatively stout, columnar, main stem (trunk or bole) that bears branches. See also bush, frutex, shrub, subshrub, suffrutex, undershrub, woody clump. |
anatropous |
|
orientation |
ovule |
Having the funiculus distally recurved and the (straight) ovule lying beside and parallel to the proximal portion of the funiculus, to which it may be adnate or adherent, the micropyle facing the ovary wall (placenta). |
hypogynous |
|
insertion |
perianth, calyx, corolla, androecium |
Entirely free from the gynoecium or any floral cup, arising from a level proximal or lateral to the base of the gynoecium. See also epigynous, perigynous. |
parietal |
|
placentation |
|
Upon the inner wall surface of a unilocular ovary, thus peripheral within the locule. |
raceme |
|
nominative |
inflorescence |
An elongate, unbranched main axis bearing pedicellate flowers inserted singly along it. |
absent |
|
presence |
|
Not occurring within the context in point. |
bifacial |
|
architecture |
|
Having two opposite broad surfaces that differ distinctly in appearance. |
epigynous |
|
insertion |
perianth, calyx, corolla, androecium |
Having its proximal portion adnate to the full length of the gynoecium, the free portion thus arising from the apex of the gynoecium. See also hypogynous, perigynous. |
subequal |
|
size |
equivalent structures |
Nearly uniform in extent. See also equal, unequal. |
monadal |
|
arrangement |
pollen |
Shed singly, or essentially so, only loosely and irregularly, if at all, coherent, each original tetrad having separated fully. |
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. |
geminicolpate |
|
architecture |
pollen grain |
Having four or more surficial grooves (colpi) disposed in pairs. |
diaphragmed |
|
architecture |
pith |
Uninterrupted by cavities but heterogeneous in texture at axis maturity, with sectors of spongy tissue separated by relatively thin transverse plates of denser tissue that occur at the nodes or are otherwise regularly spaced along the axis. |
umbellet |
|
nominative |
inflorescence |
A single set of pedicellate flowers in a compound umbel. |
suffused |
|
coloration |
|
Having two or more hues, shades, and/or intensities intermingled, the contrasting components distinguishable only submacroscopically. |
rounded |
|
base |
|
Convex overall and more or less regularly curved. |
utricle |
|
nominative |
fruit |
Dry, indehiscent, one-seeded and with the pericarp thin and free from the seed; derived from a single, superior, simple ovary. |
crassate |
|
architecture |
|
Relatively thick for the type of structure or in the taxonomic context. |
involucre 2 |
|
STRUCTURE |
|
One or more closely proximate whorls, or a compact spiral, of bracts (phyllaries) surrounding (proximal to) the compound receptacle (torus) and florets of a capitulum (head); in Asteraceae (Compositae). |
petiolar |
|
insertion |
|
Upon or otherwise directly associated with the petioles. |
contractile |
|
architecture |
structure |
Diminishing in length, or acquiring the potential energy for a sudden decrease, due to the generation of internal tension during tissue development. |
opposite 1 |
|
arrangement |
|
Disposed in pairs along the axis, the members of each pair inserted at the same level across from one another. |
