STRUCTURE |
|
A stem segment that functions as a leaf; often more or less compressed. |
|
craspedodromous, simple- |
|
venation |
|
Having a midvein that branches to either side along the length of the lamina, the secondary veins and their branches all running toward and terminating at the margin. |
|
presence |
|
CHARACTER |
|
Occurrence within the context in point. |
|
discal |
|
position |
|
Upon or otherwise directly associated with the floral disc. |
|
reproduction |
|
CHARACTER |
|
Type, morphology, disposition, function and/or dissemination of reproductive structures. |
|
secondary root |
|
STRUCTURE |
|
Any root branch that originates directly or indirectly from a primary root. |
|
fossula pl. fossulae |
= colpus, furrow, groove, sulcus, vallecula |
FEATURE |
|
An elongate depression that is relatively shallow and narrow. |
|
hastula pl. hastulae, hastulas |
= ligule misapplied |
STRUCTURE |
|
An outgrowth or enation from the petiole apex at its junction with the adaxial surface of a palmate leaf blade; often woody in texture; variously shaped, its adaxial outline usually resembling an inverted V or U, or a semicircle with the opening proximal; esp. in Arecaceae (Palmae). |
|
subcircular |
= subround; suborbicular misapplied, subrotund misapplied |
plane shape |
|
Compressed circular or very broadly elliptic, only slightly longer than wide. |
|
infructescence 2 (not recommended) |
= coenocarp, multiple fruit, syncarp; > fig, syconium |
STRUCTURE |
|
A compound fruit derived from the connate or coherent ovaries and accessory tissue(s), if any, of two or more adjacent flowers. |
|
thorn |
= spine |
STRUCTURE |
|
Any sharp, stiff, simple or branched, woody appendage having vascular tissues confluent with those of the bearing structure. "Spine" is often preferred when the appendage is homologous with a leaf or stipule, and "thorn" when it is homologous with a branch. See also prickle. |
|
ligneous |
= woody |
texture |
|
Of or resembling xylem (wood). |
|
acrodromous |
|
venation |
|
Having two or more primary and/or strongly developed secondary veins that diverge at or above the laminar base and are thence convergently arcuate toward the apex, reaching it or not. |
|
arcuate 1 |
|
course |
|
Curving more or less regularly in one direction. |
|
lunate |
= crescent-shaped |
plane shape |
|
Arcuate, broadest at the middle, and attenuate to acute ends; like the stylized outline of a first-quarter moon. |
|
bract 1 (broad sense) |
> bracteole, bractlet, phyllary, prophyll(um); >< scale |
STRUCTURE |
|
Any lateral structure ontogenetically and anatomically analogous with, and therefore presumably homologous with, but relatively smaller than, a leaf, especially when subtending an inflorescence, other reproductive structure, or portion thereof; putatively, an evolutionarily reduced leaf. |
|
nine-… |
= ennea… |
prefix |
|
Indicating presence of or constitution by nine entities of the type denoted by the term's stem; as in nine-carpelled, nine-loculed, nine-tepaled. |
|
bract 2 (strict sense) |
|
STRUCTURE |
|
Any primary or first-order lateral structure ontogenetically and anatomically analogous with, and therefore presumably homologous with, but relatively smaller than, a leaf, especially when subtending an inflorescence, other reproductive structure, or portion thereof; putatively, an evolutionarily reduced leaf. |
|
corm |
|
STRUCTURE |
|
A short, thickened, solid, usually subterranean, sometimes fleshy stem base containing stored carbohydrates and serving as a perennating organ. |
|
plumule |
= epicotyl |
STRUCTURE |
|
A distinguishable nascent shoot developed in the embryo in some taxa, consisting of a shoot axis with unexpanded internodes and one or more leaf primordia, being that portion of the embryo above the level of cotyledon insertion; the primordial shoot, when developed by the embryo within a seed; the first bud of a spermatophyte, when developed by an embryo within the seed. In other taxa the shoot is represented in the embryo only by a quiescent apical meristem at the summit of the embryonic axis. |
|
diamond-shaped |
= rhomboid |
solid shape |
|
Transversely square, broadest and longitudinally angular at the middle, regularly attenuate to angular ends, all faces essentially plane; like the stylized shape of a diamond. |
|
epicarp |
= exocarp |
STRUCTURE |
|
The outermost tissue layer of a pericarp. |
|
scalariform |
= ladder-like |
arrangement |
|
Disposed in vertical sequence with long axes horizontal and parallel. |
|
flexuous var. flexuose |
= zig-zag |
course |
|
Having alternating angular bends to either side, more or less straight between the bends. |
|
small-toothed |
= denticulate |
margin |
|
Finely toothed (dentate). See also sawtoothed (serrate), scalloped (crenate), small-scalloped (crenulate), small-sawtoothed (serrulate). |
