| Term | Synonyms | Category | Limitation | Definition |
|---|---|---|---|---|
| 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. | ||
| collar 2 | FEATURE | The junction between the sheath and blade of a leaf; esp. in Poaceae (Gramineae). | ||
| 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. | |
| 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 the number of colpi indicated by the prefix; esp. pollen grains; as in monocolpate, polycolpate, 3-colpate. | |
| colpate | = fossulate, furrowed, grooved, sulcate, valleculate | architecture | Having one or more elongate, relatively narrow and shallow depressions (colpi). | |
| …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). | |
| compound | = composite | 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). |
