stilt-rooted |
|
architecture |
plant |
Bearing and partly supported by stilt roots. |
staminal |
|
insertion |
|
Upon or otherwise directly associated with the stamens. |
appressed |
|
orientation |
lateral structure |
Angled at or near the base and closely flattened against the surface of the bearing structure, thus more or less parallel to it. |
strobiloid |
|
architecture |
flower |
Characterized by a general lack of adnation among the different sets of basic floral structures, any significant degree of fusion limited to connation within sets, thus with ovary(ies) superior and lacking a floral tube. |
imperfect |
|
architecture |
flower |
Having either stamens or pistils absent or non-functional, thus unisexual. |
presence |
|
CHARACTER |
|
Occurrence within the context in point. |
subtending |
|
insertion |
|
Arising from the axis just below and very near to the base of some other specified lateral structure. This term is meaningless if the structure that is subtended is not indicated. |
ray floret |
|
STRUCTURE |
|
A floret that has a zygomorphic corolla, is pistillate (either fertile or sterile) or neuter, and is borne in a radiate capitulum (head) peripheral (proximal) to the disc florets; in Asteraceae (Compositae). |
palate |
|
STRUCTURE |
|
The lower, prominent labium (lip) of a personate (gaping, ringent) corolla. |
calyculus 2 pl. calyculi |
|
STRUCTURE |
|
Collectively the bractlets (bracteoles) sometimes subtending (beneath or outside) the involucre in a capitulum (head); in Asteraceae (Compositae). |
sellaeform |
|
solid shape |
|
See selliform. |
infrapetiolar |
|
position |
bud |
Axillary and surrounded by the petiole base at maturity. |
syncolpate |
|
architecture |
pollen grain |
Having two or more fused or confluent surficial grooves (colpi). |
suprabasal |
|
position |
|
Just above the base of the structure in point. |
cyathiate |
|
architecture |
inflorescence |
Comprising one or more cyathia. |
pappus scale |
|
STRUCTURE |
|
A pappus element that is more or less planate and relatively thin and broad; may terminate in one or more awn- or bristle-like appendages. |
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. |
drupelet |
|
nominative |
fruit |
Diminutively drupe-like but derived from one of the simple, superior ovaries of an apocarpous flower, having a fleshy fruit wall and a hard seed (pyrene) within, a distinct constituent in an aggregate fruit; esp. in Rosaceae. |
internodal |
|
insertion |
|
Upon or otherwise directly associated with the internodes. |
mixed-craspedodromous |
|
venation |
|
Having a midvein that branches to either side along the length of the lamina, the secondary veins running thence toward the margin, some becoming indistinct before reaching it, others terminating there. |
conoidal |
|
solid shape |
|
Generally but not strictly conic. |
androgynecandrous |
|
reproduction |
taxon |
Monoecious, each inflorescence having distal and proximal sectors with only staminate flowers and between them a central sector with only pistillate ones. |
lenticel |
|
STRUCTURE |
|
A specialized, anatomically distinct structure within the periderm of a stem, consisting of comparatively spongy, sometimes suberized tissue distinct from others of the periderm; extending radially through the periderm and visible as a circular to elongate discontinuity in the color, texture, and/or relief of the outer surface of the stem; serving as a conduit for gas exchange between the stem interior and the atmosphere. |
base |
|
CHARACTER |
|
Configuration of the lowermost or proximal portion of a structure, its extent determined somewhat subjectively in relation to the shape of the structure as a whole. The concept of base varies from one descriptive context to another, since the base is not a clearly delimited, morphologically distinct entity. The terms for describing basal condition are not strictly coordinate logically — some are more inclusive than others, and some describe conditions involving what can be regarded as appendages — and precise characterization may require using more than one descriptor. The semantic antecedent of some descriptors is "base," whereas the antecedent of others is the structure as a whole (e.g., leaf ). |
disarticulating |
|
architecture |
axis |
Articulate(d) and with the main portions of the whole separating at the joints upon maturity or senescence. |
