|
elongate |
|
plane shape |
|
Longer in one dimension than in any other. |
|
parietal |
|
placentation |
|
Upon the inner wall surface of a unilocular ovary, thus peripheral within the locule. |
|
gelatinous |
|
texture |
|
Jelly-like; soft, moist, continuously cohesive, texturally homogeneous, somewhat resilient, and easily cut. |
|
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. |
|
radiant 1 |
|
architecture |
capitulum (head) |
Bearing one or more peripheral series of florets that are bisexual, pistillate, or neuter and that have relatively large actinomorphic corollas, and one or more central series of usually bisexual florets that have relatively small actinomorphic corollas; in Asteraceae (Compositae). |
|
revolute 2 |
|
vernation |
|
Each rolled abaxially inward from the lateral margins. |
|
heteropolar |
|
architecture |
pollen grain, spore |
Having morphologically evident polarity, the proximal and distal halves dissimilar. |
|
reclining |
|
habit |
axis |
Inserted above substrate level and recurved, the distal portion procumbent. |
|
anisopetalous |
|
architecture |
flower, perianth, corolla |
Having petals unequal in size and/or shape. |
|
rosette |
|
STRUCTURE |
|
A set of leaves that are strongly congested and disposed in radial symmetry about the main stem at or very near its base, seeming to arise at the same level and often overlapping laterally; esp. the overwintering leaves of perennial herbs. |
|
sectile |
|
architecture |
pollinium |
Having partially separated sectors, as though cut. |
|
involucre 1 |
|
STRUCTURE |
|
One or more closely proximate whorls, or a compact spiral, of bracts immediately subtending an inflorescence, the bracts sometimes leaf-like, sometimes petaloid. |
|
lemma pl. lemmata, lemmas |
|
STRUCTURE |
|
The proximal bract of the (usually) two that immediately subtend the flower in a grass (Poaceae) floret; the other is the palea. |
|
infructescence 1 |
|
STRUCTURE |
|
A mature (fruiting) inflorescence (static sense). |
|
spongy |
|
texture |
|
Soft, light, discontinuous but cohesive, and somewhat resilient. |
|
septicidal |
|
dehiscence |
fruit |
Splitting longitudinally into or through the suture(s) in the outer wall and, if present, through the septum(-a) between locules, the latter thus opened indirectly to the outside. |
|
coleorhiza |
|
STRUCTURE |
|
A sheath-like structure enclosing the radicle (embryonic root) in an embryo; esp. in Poaceae (Gramineae). |
|
costal |
|
insertion |
|
Upon or otherwise directly associated with the costa(e) of a laminar structure. |
|
spicate |
|
architecture |
inflorescence |
Comprising one or more spikes. |
|
costal |
|
position |
|
Upon or otherwise directly associated with the costa(e) of a laminar structure. |
|
lineolate 1 |
|
coloration |
|
Finely lineate, the lines short and often irregularly oriented. |
|
antipetalous |
|
position |
equivalent floral structures |
Each inserted directly above or below a petal. In place of this term, the phrase "opposite the petals" is often used, but that contradicts the sense of opposite as otherwise employed (arrangement of lateral structures along an axis) and should be avoided. |
|
microphyllous |
|
architecture |
plant |
Bearing microphylls. |
|
cyathium pl. cyathia |
|
nominative |
inflorescence |
Resembling a single flower, the unbranched axis very short with a terminal pistillate flower and several lateral staminate flowers, the whole subtended and to some degree enclosed by a cupulate envelope of bracts, the flowers diminutive and presumed to be evolutionarily reduced; characteristic of Euphorbia. |
|
maturation |
|
CHARACTER |
|
Timing of the attainment of functional maturity, sometimes relative to other structures, sometimes as to constituent structures relative to each other. |
