column 1 |
= gynandrium, gynostemium |
STRUCTURE |
|
A central floral structure consisting of the partly to wholly fused (connate and adnate) androecium and gynoecium; esp. in Orchidaceae. |
|
columella 2 pl. columellae, columellas |
= carpophore; < stalk |
STRUCTURE |
|
The stalk supporting a mericarp after dehiscence of a schizocarpic fruit, the central axis of the fruit having split longitudinally to yield two or four such stalks; composed of receptacular and (primarily) gynoecial tissues; esp. in Apiaceae (Umbelliferae). |
|
columella 1 pl. columellae, columellas |
= carpophore; < stalk |
STRUCTURE |
|
Any pedestal-like prolongation of a floral receptacle extending beyond the distalmost level of perianth insertion and bearing the gynoecium. |
|
colpus pl. colpi |
= fossula, furrow, groove, sulcus, vallecula |
FEATURE |
|
An elongate depression that is relatively shallow and narrow. |
|
colporate |
|
architecture |
pollen grain |
Having one or more elongate, relatively narrow and shallow depressions (colpi), each containing a pore. |
|
colpate |
= fossulate, furrowed, grooved, sulcate, valleculate |
architecture |
|
Having one or more elongate, relatively narrow and shallow depressions (colpi). |
|
coloration |
|
CHARACTER |
|
Hue(s), intensity(ies), and/or pattern (if any) of coloring. When more than one hue and/or intensity is involved, a term describing the pattern of contrast will be applicable, and the description as a whole should be phrased to indicate the particular role of each in the pattern; e.g., "ovaries striate, yellow on green"; "petals pink, spotted yellow basally"; "sepals green, suffused with red". |
|
collateral |
|
insertion |
buds |
In pairs within or immediately straddling the leaf axils, the members of a pair lateral to one another. |
|
collateral |
|
position |
buds |
In pairs within or immediately straddling the leaf axils, the members of a pair lateral to one another. |
|
collar 2 |
|
FEATURE |
|
The junction between the sheath and blade of a leaf; esp. in Poaceae (Gramineae). |
|
collar 1 |
|
STRUCTURE |
|
The free portion (if any) of a floral tube, distal to its casing and/or neck when one or both is/are present. |
|
coleorhiza |
|
STRUCTURE |
|
A sheath-like structure enclosing the radicle (embryonic root) in an embryo; esp. in Poaceae (Gramineae). |
|
coherent |
|
fusion |
equivalent structures |
Joined superficially, with no significant histological continuity. |
|
coetaneous |
|
maturation |
dissimilar structures |
Maturing concurrently. This adjective is frequently used to mean contemporary maturation of leaves and flowers, but without actually stipulating that those are the structures involved. Such usage is erroneous according to the construction and literal meaning of the term, which properly applies to structures, not to the taxon or plant. See also synanthous. |
|
coenocarp |
= infructescence (not recommended), multiple fruit, syncarp; > fig, syconium |
nominative |
fruit |
Compound and derived from the connate or coherent ovaries and accessory tissue(s), if any, of two or more adjacent flowers. |
|
cochleate |
= snail-shell-shaped |
solid shape |
|
Relatively broad and short, basically round in transverse section, resembling a rapidly tapering spire overall, the exterior helically convoluted; like a snail shell. |
|
cochlear |
|
aestivation |
|
Imbricate with one member larger than and exterior to the others, parallel to one that is internal to all the others, strongly incurved, and enclosing the others. |
|
coccus pl. cocci |
= mericarp |
STRUCTURE |
|
One of the segments of a dehisced schizocarp; usually one-seeded and itself indehiscent. |
|
cobwebby |
= arachnoid |
pubescence |
|
Of fairly sparse, fine, white, loosely tangled, capillate trichomes. |
|
coating |
|
CHARACTER |
|
Exudate that covers the surface proper. See also indumentum (vesture), pubescence. |
|
coalescent |
|
fusion |
equivalent and/or dissimilar structures |
Partially and irregularly coherent and/or adherent. |
|
clustered 2 |
= gregarious |
habit |
plants |
Growing in loose aggretations. See also cespitose. |
|
clustered 1 |
|
arrangement |
|
Disposed in one or more aggregates, the members of each inserted close together, thence widely divergent from one another. |
|
club-shaped |
= clavate |
solid shape |
|
Elongate and basically round in transverse section, the diameter greatest at or near a blunt apex, thence attenuate toward the base, the degree of taper greatest between the middle and the upper quarter. |
|
cloying |
|
odor |
|
Sickeningly sweet. |
