floating 1 |
|
habit |
plant |
Buoyant and growing entirely at or near the surface of water, not rooted in any substrate. |
vegetative |
< apomictic, asexual |
reproduction |
plant |
Producing new plants asexually by proliferation or fragmentation of sterile tissue, without formation of embryos (or seeds). The logical antecedent of this term is "reproduction," not the taxon in point or "plants," and syntax should be governed accordingly. Whenever this mode of reproduction is noted, the relevant propagative structures should be identified. |
herb |
|
nominative |
plant |
Annual, biennial, or perennial with no woody (lignified) tissue in any part of the shoot; when persisting over more than one growing season, the parts of the shoot dying back seasonally. |
sarmentose |
= runnering, stoloniferous |
architecture |
plant |
Producing stolons (runners), by means of which it propagates vegetatively. |
herbaceous 1 |
|
habit |
plant |
Having no significant degree of secondary growth in any part of the shoot, which thus does not develop woody (lignified) tissue. |
imbricate(d) 2 |
= overlapping |
arrangement |
planate structures |
Overlapping one another laterally and/or longitudinally. |
overlapping 2 |
= imbricate(d) |
arrangement |
planate structures |
Overlapping one another laterally and/or longitudinally. |
valvate 2 |
|
arrangement |
planate structures |
Not overlapping, adjacent members laterally contiguous at their margins. |
oblique 2 |
|
orientation |
planate lateral structure |
Lying in a plane not coincident with the one defined by its longitudinal axis and that of the bearing structure. |
continuous 2 |
= solid |
architecture |
pith |
Uninterrupted by cavities and essentially homogeneous in texture at axis maturity. |
chambered |
|
architecture |
pith |
Interrupted by cavities that are more or less regularly spaced along the axis and that result from disintegration of tissue prior to axis maturity. |
solid |
= continuous |
architecture |
pith |
Uninterrupted by cavities and essentially homogeneous in texture at axis maturity. |
diaphragmed |
|
architecture |
pith |
Uninterrupted by cavities but heterogeneous in texture at axis maturity, with sectors of spongy tissue separated by relatively thin transverse plates of denser tissue that occur at the nodes or are otherwise regularly spaced along the axis. |
cyathiform |
|
solid shape |
perianth, calyx, corolla, pappus |
Having a cupulate tube and an indistinct, erect limb. See also cotyliform, urceolate (urn-shaped). |
perigynous |
|
insertion |
perianth, calyx, corolla, androecium |
Having its proximal portion adnate to part of the length of the gynoecium, or fused in a separate floral cup that extends part of the length of the gynoecium, the free distal portion thus arising at a level between the base and apex of the gynoecium. See also epigynous, hypogynous. |
epigynous |
|
insertion |
perianth, calyx, corolla, androecium |
Having its proximal portion adnate to the full length of the gynoecium, the free portion thus arising from the apex of the gynoecium. See also hypogynous, perigynous. |
hypogynous |
|
insertion |
perianth, calyx, corolla, androecium |
Entirely free from the gynoecium or any floral cup, arising from a level proximal or lateral to the base of the gynoecium. See also epigynous, perigynous. |
actinomorphic |
= regular |
architecture |
perianth, calyx, corolla |
Radially symmetric; divisible into two essentially equal portions along any median longitudinal plane. |
two-lipped |
= bilabiate; < labiate, lipped |
architecture |
perianth, calyx, corolla |
Strongly zygomorphic with connate and/or coherent members whose distal portions form two unequal, opposing, lip-like structures, one adaxial, one abaxial. See also gaping (personate, ringent). |
urceolate |
= urn-shaped |
solid shape |
perianth, calyx, corolla |
Having a truncate-ellipsoid tube and a distinct, erect limb, the whole somewhat constricted between tube and limb. See also cotyliform, cyathiform. |
urn-shaped |
= urceolate |
solid shape |
perianth, calyx, corolla |
Having a truncate-ellipsoid tube and a distinct, erect limb, the whole somewhat constricted between tube and limb. See also cotyliform, cyathiform. |
irregular 1 |
|
architecture |
perianth, calyx, corolla |
Imperfectly actinomorphic, the constituents disposed symmetrically but unequal in size and/or shape. See also peloric. |
lipped |
= labiate; > bilabiate, one-lipped, two-lipped, unilabiate |
architecture |
perianth, calyx, corolla |
Strongly zygomorphic with connate and/or coherent members some or all of whose distal portions form one or two lip-like structures. |
infundibular |
= funnelform, funnel-shaped |
solid shape |
perianth, calyx, corolla |
Having a narrowly obconic tube and a spreading limb, the transition between them smooth. |
labiate |
= lipped; > bilabiate, one-lipped, two-lipped, unilabiate |
architecture |
perianth, calyx, corolla |
Strongly zygomorphic with connate and/or coherent members some or all of whose distal portions form one or two lip-like structures. |
