|
cyathiform |
|
solid shape |
perianth, calyx, corolla, pappus |
Having a cupulate tube and an indistinct, erect limb. See also cotyliform, urceolate (urn-shaped). |
|
aestivation |
|
CHARACTER |
|
Disposition of perianth (undifferentiated), calyx, or corolla members in the bud. |
|
matted |
|
habit |
plants |
Growing in extensive, low, dense aggregations, sometimes with the stems of different plants intertwined. |
|
nectariferous |
|
exudation |
|
Producing and secreting nectar; when glands are nectariferous, they are usually indicated nominatively as nectaries. |
|
didynamous |
|
architecture |
flower, androecium |
Diadelphous with two stamens in each set. See also tetradynamous. |
|
symmetric(al) 1 |
|
architecture |
|
Divisible into essentially equal halves along one or more lines or planes. |
|
berry |
|
nominative |
fruit |
Indehiscent, few- to many-seeded, and derived from a single, simple or compound ovary; fleshy throughout except for the seeds. See also hesperidium, pepo. |
|
obtrulloid |
|
solid shape |
|
Inversely trulloid. |
|
calyculate 1 |
|
architecture |
capitulum (head) |
With the involucre subtended by a calyculus; in Asteraceae (Compositae). |
|
nutrition |
|
CHARACTER |
|
Mode of acquiring nutrients. |
|
bud-scale scar |
|
FEATURE |
|
A scar on a stem due to abscission of a bud scale. The scar(s) encircle(s) the axis to which the bud was terminal, each single scar having an outline like that of a transverse section through the base of the bud scale that was inserted there. Sets of bud scale scars (one set per bud) usually delimit seasonal stem growth increments in temperate zone taxa. |
|
tendril |
|
STRUCTURE |
|
A slender stem branch, modified leaf, or portion of a leaf that twines about a supporting structure. |
|
epichilium |
|
STRUCTURE |
|
The distal portion of a labellum (lip) that has distinct proximal, distal, and sometimes also central parts; in Orchidaceae. See also hypochilium, mesochilium. |
|
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. |
|
trulloid |
|
solid shape |
|
Elongate, basically square in transverse section, broadest below the middle, regularly attenuate to angular ends, all faces essentially plane. See also obtrulloid. |
|
carinal |
|
aestivation |
|
Having the petals of the keel (carina) enclosing the others. |
|
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. |
|
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. |
