|
filament |
|
STRUCTURE |
|
The stalk, when present, of a stamen, clearly differentiated from and bearing at its summit an anther. |
|
cartilaginous |
= cartilage-like |
texture |
|
Firm, dense, tough, somewhat pliable, and resilient, like human cartilage. |
|
scape |
|
STRUCTURE |
|
A leafless, essentially naked, inflorescence-bearing stem (or peduncle) arising directly from a caudex or rhizome, its point of insertion slightly beneath, at, or slightly above the substrate surface. |
|
pale 2 |
= palea, palet |
STRUCTURE |
|
The upper or distal of the (usually) two distinctive bracts immediately subtending the flower in a grass (Poaceae) spikelet. |
|
indument |
|
STRUCTURE / SUBSTANCE |
|
See indumentum. |
|
diffuse-porous |
|
porosity |
|
Homogeneously porous, the vessels not differentially disposed by size or number. |
|
subterranean |
= hypogeal, hypogeous |
location |
|
Within the ground, beneath its surface. |
|
proximal |
> basal |
insertion |
|
Upon or associated with the portion of a structure closest to its developmental origin. |
|
base |
|
CHARACTER |
|
Configuration of the lowermost or proximal portion of a structure, its extent determined somewhat subjectively in relation to the shape of the structure as a whole. The concept of base varies from one descriptive context to another, since the base is not a clearly delimited, morphologically distinct entity. The terms for describing basal condition are not strictly coordinate logically — some are more inclusive than others, and some describe conditions involving what can be regarded as appendages — and precise characterization may require using more than one descriptor. The semantic antecedent of some descriptors is "base," whereas the antecedent of others is the structure as a whole (e.g., leaf ). |
|
ellipsoid(al) |
|
solid shape |
|
Elliptic in any median longitudinal section; elongate, transversely circular, broadest at the middle, and symmetrically convex-attenuate to rounded ends. See also oblong. |
|
mammose |
|
solid shape |
|
Having mammae. |
|
sigmoid 2 |
= S-shaped |
solid shape |
|
Elongate with more or less constant width or diameter and curved more or less regularly first in one direction and then in the opposite direction, like the letter S. |
|
petal |
|
STRUCTURE |
|
One of the one or more constituent members of a corolla; colored and showy in many taxa, inconspicuous in size and/or color in others; may be distinct or else connate with one or more others, and/or may be free or else adnate to one or more other floral structures. |
|
laevigate 1 |
|
relief |
|
Very smooth. |
|
testes-shaped |
= testicular |
solid shape |
|
Bilaterally symmetrical, each side essentially oblate and constrictedly confluent with the other; like the overall shape of a pair of mammalian testes. |
|
bundled 2 (not recommended) |
= fascicled, fasciculate |
arrangement |
|
Disposed in one or more fascicles, the members of each inserted close together and only slightly if at all divergent from one another. |
|
canalicular |
|
position |
|
Upon or otherwise directly associated with the channel of a petiole or petiolule. |
|
navicular |
= boat-shaped, cymbiform |
solid shape |
|
Like the generalized form of a boat hull, the walls relatively thin to moderately thick, the interior essentially empty and open along one side. |
|
whorl |
= cycle, series, verticil |
STRUCTURE |
|
A set of three or more lateral structures that are inserted around an axis at the same level. |
|
one-sided 1 |
= unilateral |
architecture |
|
Having only one side, as compared with presumably equivalent, bilaterally symmetric structures. |
|
half-terete |
= semiterete |
solid shape |
|
Terete but flattened on one side. |
|
costule |
|
STRUCTURE |
|
A longitudinal primary vein in a diminutive laminar structure, such as the blade of a leaflet, pinna or pinnule; a diminutive costa (rib). |
|
spurred |
= calcarate |
base |
|
Having a relatively slender protrusion resembling a spur. |
|
position |
|
CHARACTER |
|
Location or disposition with reference to some dissimilar structure(s) or larger context. The lexicons relating to position and insertion overlap to a great degree, since these two morphological concepts are often inseparable in practice. Also overlaps conceptually with arrangement, habit, orientation, and shape. |
|
awl-shaped 1 |
= subulate |
plane shape |
|
Narrowly triangular or truncate-triangular and broadest at the base; like the outline of the lateral face of an awl. |
