| Term | Synonyms | Category | Limitation | Definition |
|---|---|---|---|---|
| corona pl. coronae, coronas | > gynostegium | STRUCTURE | A crown-like set of connate or distinct appendages or enations borne upon a corolla or androecium or between them. | |
| coroniform | = crown-shaped | solid shape | Shortly and broadly tubular overall, circumferentially continuous at the base, distally so or not; like a monarch's crown. | |
| corrugate 1 | = crumpled | aestivation | Having members tightly and irregularly folded, the whole appearing as though wadded upon emergence. | |
| corrugate 2 | = rugose, wrinkled | relief | Having irregular, narrow ridges or creases, the intervening areas flat or only slightly concave or convex, appearing overall as though crumpled and then spread out. See also rugulose. | |
| corticate | = hard-coated | texture | Having a hard exterior layer and a distinct, softer interior. | |
| corymb | nominative | inflorescence | An indeterminate, more or less condensed raceme with the pedicels progressively shorter toward the distal end, the flowers all borne at approximately the same level, the whole generally plane or convex at the top, the flowers maturing from the edge inward (i.e., the proximal or outer flowers maturing first). | |
| corymbiform | = corymb-like | architecture | capitulescence, inflorescence | Resembling a corymb, but not strictly such. |
| corymb-like | = corymbiform | architecture | capitulescence, inflorescence | Resembling a corymb, but not strictly such. |
| corymbose | architecture | inflorescence | Comprising one or more corymbs. | |
| costal | insertion | Upon or otherwise directly associated with the costa(e) of a laminar structure. | ||
| costal | position | Upon or otherwise directly associated with the costa(e) of a laminar structure. | ||
| costa pl. costae | = rib; > midnerve (not recommended), midrib, midvein; >< lateral vein | STRUCTURE | A primary vein of a laminar structure, having a longitudinal course, either medial or lateral, often prominent. See also secondary vein, tertiary vein, veinlet. | |
| costate | = ribbed | architecture | laminar structure | Having one or more costae (ribs). |
| costule | STRUCTURE | A longitudinal primary vein in a diminutive laminar structure, such as the blade of a leaflet, pinna or pinnule; a diminutive costa (rib). | ||
| cottony | > lanuginose | pubescence | Of or bearing relatively long and fine, intertwined, somewhat matted, capillate trichomes. See also lanuginose. | |
| cotyledon | = seed leaf | STRUCTURE | Any of the one or more primary foliar structures of an embryonic seed plant, proximal to all succeeding leaf primordia; sometimes serving as a storage organ for food reserves in the seed, as in peas and beans. | |
| cotyliform | solid shape | perianth, calyx, corolla | Having a short, relatively broad, cupulate tube and a well differentiated, erect limb. See also cyathiform, urceolate (urn-shaped). | |
| cotyloid | architecture | flower | Having general adnation among the different sets of floral structures, thus having the ovary inferior and/or having a floral tube. | |
| course | CHARACTER | Linear pattern of the centerline through the length of an axis or vein. | ||
| craspedodromous, mixed- | 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. | ||
| craspedodromous, simple- | venation | Having a midvein that branches to either side along the length of the lamina, the secondary veins and their branches all running toward and terminating at the margin. | ||
| crassate | architecture | Relatively thick for the type of structure or in the taxonomic context. | ||
| crateriform | = goblet-shaped | solid shape | Having a distal, concave, relatively thin-walled, basically hemispherical portion surmounting a much narrower, transversely round, pedestal-like base. | |
| creeping | = repent | habit | axis | Procumbent and rooting adventitiously at intervals along its length. |
| crena pl. crenae | = scallop | FEATURE | A rounded, marginal convexity or concavity in a series of such that alternate regularly and are oriented more or less perpendicular to the generalized perimeter of a laminar structure. See also crenule (scalloplet), dens (tooth), sawtooth, sawtoothlet, toothlet. |
