discoid 1 |
= disciform |
solid shape |
|
Relatively thin with two round, plane or convex, opposite broad faces and a rounded circumferential edge; like a disc. See also lenticular (biconvex, lens-shaped), meniscoid, placentiform (placenta-shaped), trochlear (pulley-wheel-shaped). |
inflorescence 1 |
|
architecture |
|
Mode or progressive pattern of bearing flowers; most appropriately described using adjectival terms. |
sulcate |
= colpate, fossulate, furrowed, grooved, valleculate |
architecture |
|
Having one or more elongate, relatively narrow and shallow depressions (sulci). |
buckler-shaped |
= scutate, scutiform |
solid shape |
|
Relatively thin with opposite broad oblong faces, planate to shallowly concave-convex, sometimes thickened about the periphery such that each face has a marginal rim; like an oblong shield. See also platter-shaped (scutellate, scutelliform), which is not clearly distinct in its application. |
reniform 2 |
= kidney-shaped |
solid shape |
|
Thickly elongate and arcuate, circular or compressed-circular in transverse section, each end bluntly rounded; like the generalized shape of a human kidney. |
commissure |
|
FEATURE |
|
Precisely, the joint or common boundary between the facing surfaces of two coherent or mutually appressed structures such as mericarps or stigmas, but traditionally (though imprecisely) applied to such a facing surface itself. |
unilateral 3 |
= one-sided |
insertion |
|
Upon or arising from one side only of the bearing structure. |
nectariferous |
|
exudation |
|
Producing and secreting nectar; when glands are nectariferous, they are usually indicated nominatively as nectaries. |
galea pl. galeae, galeas |
|
STRUCTURE |
|
A galeate (galeiform, helmet-shaped) sepal or petal in a zygomorphic calyx or corolla, differing markedly in shape from and sometimes partially enclosing the other sepals or petals. |
petiolule |
< stalk |
STRUCTURE |
|
The stalk, when present, of a leaflet, analogous to the petiole of a leaf. |
carinate |
= keeled |
solid shape |
|
Having an elongate median longitudinal ridge that is basically triangular in transverse section, resembling the keel of a boat; esp. a leaf blade or sheath, glume, lemma, palea, sepal or petal. |
theca pl. thecae |
= pollen sac |
STRUCTURE |
|
Any of the one, two or four ontogenetically distinct, pollen-producing sectors (microsporangia) of an anther. In some taxa the walls between pairs of adjacent thecae break down as an anther approaches maturity, the mature anther thus ultimately containing half as many locules as thecae. |
sausage-shaped |
= botuliform |
solid shape |
|
Arcuately cylindric with rounded ends. |
opposite 2 |
|
arrangement |
|
Having the members of each whorl inserted directly above and/or below those of the next adjacent whorl(s). See also antipetalous, antisepalous. |
squamule 2 |
= squamella; < scale |
STRUCTURE |
|
A small, dry bract borne on the compound receptacle (torus) of a capitulum (head); in Asteraceae (Compositae). |
primary root |
> taproot |
STRUCTURE |
|
The one, central root directly basal to a shoot, developing directly from the embryonic radicle; the first-formed root of a plant, being the only one truly central in nature (i.e., belonging to the original central axis of the plant). All other roots of a plant develop subsequently and are lateral in nature. The primary root may be permanently dominant, developing into a taproot; otherwise it may be transitory or become functionally subordinate, with secondary and/or adventitious roots becoming dominant. |
boat-shaped |
= cymbiform, navicular |
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. |
close |
= approximate |
arrangement |
|
Disposed relatively near to one another. |
lorate |
= liguliform, strap-shaped |
solid shape |
|
Elongate and relatively thin with the opposite faces more or less plane and moderately narrow, their edges more or less straight and parallel over most of their length; resembling a strap. |
fovea pl. foveae |
= pit, scrobis |
FEATURE |
|
A small, rounded depression. |
setaceous |
= bristle-shaped, setiform |
solid shape |
|
Elongate, slender, terete, straight, terminating in a fine point, and apparently stiff; like a bristle. |
knee 1 |
|
STRUCTURE |
|
An abrupt bend in an axial or other elongate structure. |
coroniform |
= crown-shaped |
solid shape |
|
Shortly and broadly tubular overall, circumferentially continuous at the base, distally so or not; like a monarch's crown. |
mucilaginous 1 |
= mucous; < glutinous |
coating |
|
Of a slimy substance, or becoming so upon wetting. |
viscid 1 |
< glutinous |
coating |
|
Of a sticky substance. |
