|
fan-shaped |
= flabellate, flabelliform |
solid shape |
|
Strongly compressed, broadest near the apex and attenuate to a narrow base, plaited longitudinally, the alternating folds radiating from the base, the whole basically triangular in broad aspect; like a partially expanded folding fan. |
|
septate 1 |

architecture |
|
Having one or more septa. |
|
furrowed |
= colpate, fossulate, grooved, sulcate, valleculate |
architecture |
|
Having one or more elongate, relatively narrow and shallow depressions (furrows). |
|
spur 1 |
|
STRUCTURE |
|
A hollow protrusion from a calyx or corolla, often nectariferous. |
|
irregular 2 |
|
course |
|
Deviating asymmetrically from a straight line. |
|
translucent |
< hyaline, pellucid |
coloration |
|
Transmitting light uniformly and diffusely. See also transparent. |
|
verrucose |

relief |
|
Covered with small, relatively broad, irregularly shaped, obtuse protrusions. |
|
asymmetric(al) 1 |
|
plane shape |
|
Not divisible into essentially equal halves along any line or plane. |
|
mealy 1 |
= farinaceous; < crumbling, fatiscent |
texture |
|
Of or bearing minute, relatively stout trichomes that are collectively meal- or flour-like and easily detached. |
|
oblate |
|
solid shape |
|
Symmetrically elongate and broader than long perpendicular to the developmental or polar axis. |
|
cladode |
= cladophyll, phylloclade |
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). |
|
acropetal |
|
development |
|
Proceeding toward the apex, thus more advanced basally or proximally than apically or distally within a given frame of reference. |
|
arcuate 2 |
|
plane shape |
|
Elongate and more or less regularly curved from one end to the other, one side convex, the opposite concave. |
