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. |
|
papillose |
= papillate |
relief |
|
Having small, conoidal protrusions overall; appearing pimply. |
|
corky |
= suberous |
texture |
|
Firm, relatively light, discontinuous but strongly cohesive, and resilient. |
|
plumose |
= feather-shaped |
solid shape |
|
Having a slender central axis bearing two opposite ranks of numerous, closely proximate, ascending, very slender branches or appendages; resembling the generalized form of a feather. |
|
epicalyx pl. epicalyces |
= calyculus |
STRUCTURE |
|
A whorl of bracts immediately subtending (beneath or outside) a calyx. |
|
scabrous 2 |
= rough, scabrate, scabrid, scabridous |
relief |
|
Having small, stout, stiff, more or less acute protrusions. |
|
flexuose |
|
course |
|
See flexuous. |
|
small-scalloped |
= crenulate |
margin |
|
Finely scalloped (crenate). See also sawtoothed (serrate), small-sawtoothed (serrulate), small-toothed (denticulate), toothed (dentate). |
|
gummy |
|
texture |
|
Highly viscous and sticky, liquid or more or less deformably solid, sometimes more or less elastic. |
|
stoma 2 (strict sense) pl. stomata |
= stomatal pore |
FEATURE |
|
The aperture between and regulated by the two guard cells of a stomate (stomatal apparatus). |
|
tartareous |
= tartar-like |
relief |
|
Rough and crumbling spontaneously, becoming erose. |
|
xylem |
= wood |
STRUCTURE |
|
The water-conducting and usually main supporting tissue of a plant or portion thereof, characterized by the presence of tracheary elements (tracheids and sometimes vessel elements); the lignified tissue of a plant or component structure, composed almost entirely of secondary tissue, i.e., that derived by secondary or lateral growth from a cambium in structures a season or more old. See also sapwood, heartwood. |
|
multi… |
= many-…, pluri…, poly… |
prefix |
|
Indicating presence of or constitution by a relatively large number of entities of the type denoted by the term's stem; as in multicarpellate, multicellular, multifacial, multiseriate. See also oligo… (few-…). |
