symbiotic |
|
nutrition |
plant |
Partially dependent for essential nourishment upon other living organisms that derive some reciprocal benefit from the relationship. |
superaxillary |
|
position |
|
Internodal but close to and directly above the axil(s). |
drooping |
|
orientation |
|
Erect to salient (patent, porrect, spreading) proximally and curving downward distally. |
nutlet |
|
nominative |
fruit |
A small, relatively hard-coated mericarp; esp. in Lamiaceae (Labiatae), Verbenaceae. |
thermocleistogamous |
|
reproduction |
flower |
Normally chasmogamous but facultatively cleistogamous during periods of lower-than-normal temperature. |
opposite 1 |
|
arrangement |
|
Disposed in pairs along the axis, the members of each pair inserted at the same level across from one another. |
barb 1 |
|
STRUCTURE |
|
Any relatively short, stiff, sharp, acutely inserted or bent, antrorse or retrorse, terminal or lateral appendage. |
faceted |
|
solid shape |
|
Having numerous, relatively small, flat or shallowly curved portions of the external surface that are bounded by more or less distinct angular discontinuities in that surface. |
fluted |
|
solid shape |
|
Having rounded to angular longitudinal grooves. |
flanged |
|
solid shape |
|
Having a relatively broad circumferential rim or ridge that protrudes laterally. |
prophyllar |
|
position |
|
Upon or otherwise directly associated with the prophylls (bracteoles, bractlets). |
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. |
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. |
allagostemonous |
|
architecture |
flower, androecium |
Having the stamens inserted alternately upon petals and the receptacle. |
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. |
