glochidiate |
|
pubescence |
|
Bearing glochids (glochidia). |
ramal |
|
insertion |
|
Upon or otherwise directly associated with the stem branches. |
barbellulate |
|
architecture |
|
Bearing one or more barbellules (barbellulae). |
pseudoaxillary |
|
position |
|
Only apparently axillary; originally extraaxillary but displaced to the axil by differential growth during development. |
repand |
|
margin |
|
Gently or shallowly sinuate. |
sheath (leaf) |
|
STRUCTURE |
|
The lower (basal or proximal), fundamentally laminar but strongly involute portion of one of the non-petiolate leaves characteristic of most monocotyledons (Liliidae); distinct from the leaf blade, which, when present, is borne distally upon it; analogous, though not necessarily homologous, with a petiole; usually more or less completely enclosing a portion of the stem above the node from which the leaf is borne. |
bifacial |
|
architecture |
|
Having two opposite broad surfaces that differ distinctly in appearance. |
salt-excreting |
|
exudation |
|
Accumulating salt and discharging it directly to the exterior in a concentrated aqueous solution, the salt then crystallizing on the exterior following evaporation of the fluid medium; when salt-excreting glands are indicated in the nominative, usually they are called simply salt glands. |
syncarpous |
|
architecture |
flower, gynoecium |
Having one or more compound pistils. |
polyplicate |
|
architecture |
pollen grain |
Inaperturate with meridional folds, thus appearing longitudinally wrinkled. |
abortive |
|
maturation |
spore, pollen, seed |
Never attaining functional maturity due to defective or arrested development. |
strict |
|
course |
|
Lacking any curve or bend. |
apostemonous |
|
architecture |
flower, androecium |
Having two or more distinct stamens; having the stamens unfused. |
longitudinal 1 |
|
dehiscence |
|
Parallel to the central axis. |
reticulodromous |
|
venation |
|
Having a single median primary vein that branches to either side along the length of the lamina, the secondary veins running thence toward the margin, branching repeatedly, becoming less distinct, and yielding a dense higher-order reticulum near the margin. |
terrestrial |
|
habit |
plant |
Growing upon the ground, usually rooted in it. |
floating 1 |
|
habit |
plant |
Buoyant and growing entirely at or near the surface of water, not rooted in any substrate. |
prop root |
|
STRUCTURE |
|
A relatively stout adventitious root arising from the lower portion of a main stem and extending outward and downward toward the substrate, within which it ultimately becomes anchored, thus buttressing the aboveground portion of the plant. |
calyptriform |
|
solid shape |
|
Hollow, roughly circular in cross-section, broader and open distally, and tapering to a closed apex, like a candle snuffer or elongate hood. |
marginal |
|
insertion |
|
Upon or otherwise directly associated with the margins. |
squarrose |
|
orientation |
lateral structure |
Having the proximal portion appressed and the distal portion deflexed, the latter more or less perpendicular to the surface of the bearing structure. |
aromatic |
|
odor |
|
Having a distinct odor; usually restricted to pleasant odors. |
involucre 1 |
|
STRUCTURE |
|
One or more closely proximate whorls, or a compact spiral, of bracts immediately subtending an inflorescence, the bracts sometimes leaf-like, sometimes petaloid. |
corolla pl. corollae, corollas |
|
STRUCTURE |
|
Collectively, the petals of a flower, whether distinct or connate; the inner or distal envelope of a differentiated perianth, whether the other envelope (calyx) is actually present or is deemed to be absent due to evolutionary reduction. |
