STRUCTURE |

|
collar 2 |
|
FEATURE |
|
The junction between the sheath and blade of a leaf; esp. in Poaceae (Gramineae). |

insertion |
buds |
In pairs within or immediately straddling the leaf axils, the members of a pair lateral to one another. |

In pairs within or immediately straddling the leaf axils, the members of a pair lateral to one another. |
|
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". |
|
colpate |
= fossulate, furrowed, grooved, sulcate, valleculate |
architecture |
|
Having one or more elongate, relatively narrow and shallow depressions (colpi). |
|
…colpate |
= …fossulate, …furrowed, …grooved, …sulcate, …valleculate |
architecture |
|
Having the number of colpi indicated by the prefix; esp. pollen grains; as in monocolpate, polycolpate, 3-colpate. |
|
…colporate |
|
architecture |
pollen grain |
Having the number of colpi indicated by the prefix, each containing a pore; as in dicolporate, 3-colporate. |
|
colporate |
|
architecture |
pollen grain |
Having one or more elongate, relatively narrow and shallow depressions (colpi), each containing a pore. |
|
colpus pl. colpi |
= fossula, furrow, groove, sulcus, vallecula |
FEATURE |
|
An elongate depression that is relatively shallow and narrow. |
|
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. |
|
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). |
|
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. |
|
column 2 |
|
STRUCTURE |
|
A fused androecium (connate stamens) closely surrounding but free from the gynoecium; esp. in Malvaceae. |
|
column foot |
= mentum |
STRUCTURE |
|
A lateral, often nectariferous protrusion from the proximal portion of a column, opposite the labellum, projecting in front of the rest of the flower; in Orchidaceae. |
|
coma pl. comae, comas |
< tuft |
STRUCTURE |
|
A prominent single tuft of relatively long and slender, flexible, capillate trichomes; esp. from a seed, as in Asclepias (Asclepiadaceae). |
|
comb-shaped |
= pectinate |
plane shape |
|
Finely divided, the divisions slender, oriented more or less perpendicular to the central axis, and resembling the teeth of a comb. |
|
commissure |
|
FEATURE |
|
Precisely, the joint or common boundary between the facing surfaces of two coherent or mutually appressed structures such as mericarps or stigmas, but traditionally (though imprecisely) applied to such a facing surface itself. |
|
comose |
|
pubescence |
|
Bearing a prominent single tuft of relatively long and slender, flexible, capillate trichomes (coma). |
|
compact |
= congested, crowded |
architecture |
|
Having equivalent constituent parts disposed very near to one another. |
|
complanate |
= compressed; < flattened |
solid shape |
|
Flattened bilaterally, parallel to the longitudinal axis, as though pressed or squeezed from opposing sides, the external surface otherwise basically convex. This term usually implies a strong degree of flattening. See also depressed, obcompressed. |
|
complete |
|
architecture |
flower |
Having all sets of basic floral structures (calyx and corolla, or else undifferentiated perianth; androecium; and gynoecium) present and functionally normal. |
|
complex |
|
architecture |
|
Comprising two or more basic structural entities, at least two of which are dissimilar. |
|
composite |
= compound |
architecture |
|
Unitary as a whole but comprising two or more equivalent substructural entities, these topologically distinct (e.g., leaflets in a compound leaf) or not (e.g., carpels in a compound pistil). |
