Term Synonyms Category Limitation Definition
cryptic coloration Similar to its natural background, from which it is not readily distinguished.
cryptocotyloid germination seed Having the cotyledon(s) remaining inside the seed coat.
cuboid solid shape Generally but not strictly cubic; more or less equilaterally six-sided, each side basically square.
cucullate 1 = hooded architecture Bearing, incorporating, or surmounted by a hood-shaped structure.
cucullate 2 = cuculliform, hood-shaped solid shape Convex or compressed-convex overall with a distal peak or ridge, relatively thin-walled and essentially hollow with the interior open to one side below the distal portion; resembling a hood or cowl. See also galeate (galeiform, helmet-shaped), which overlaps conceptually.
cuculliform = cucullate, hood-shaped solid shape Convex or compressed-convex overall with a distal peak or ridge, relatively thin-walled and essentially hollow with the interior open to one side below the distal portion; resembling a hood or cowl. See also galeiform (galeate, helmet-shaped), which overlaps conceptually.
cucullus pl. cuculli = hood STRUCTURE A cucullate (cuculliform) structure or component, esp. in an inflorescence or flower.
culm < cane, stem STRUCTURE A stem of a sedge (Cyperaceae) or grass (Poaceae), usually hollow. Use of this term or cane instead of stem is a matter of tradition and preference, not of descriptive precision or necessity.
cuneate 1 = obtriangular, wedge-shaped base laminar structure Attenuate with the sides more or less straight and intersecting at an acute angle.
cuneate 2 = obtriangular, wedge-shaped plane shape Inversely triangular; like the outline of the broad lateral face of a wedge, broadest at the apex. See also obdeltate.
cuniculate solid shape elongate structure Hollow over a significant part of its length, the interior open at the end of the hollow portion.
cup-shaped = calyciform, cupulate solid shape Truncate-globose with the distal margin more or less entire; like the bowl of a cup.
cupulate = calyciform, cup-shaped solid shape Truncate-globose with the distal margin more or less entire; like the bowl of a cup.
cupule STRUCTURE A cup-like structure inserted at the base of a fruit, partially enclosing it or not; composed of a persistent, usually dried, sometimes hardened involucre, perianth, or portion thereof, the constituent parts often coalescent, yielding a unitary structure.
curly = crispate, crisped margin Having closely and irregularly spaced, irregularly shaped, often compound convexities that curve irregularly through three dimensions.
cushion-shaped = mound-shaped, pulvinate, pulviniform solid shape Essentially round in transverse section, much broader than long or high, with a convex distal face that intersects either a more or less plane proximal face or, when the structure is sessile, its bearing surface.
cuspidate apex Tapering gradually to a rigid tip composed of both vascular and laminar tissues.
cut = incised, lacerate, torn; > laciniate, slashed plane shape Having straight to irregular lines of separation extending inward from the margin. See also cleft (dissected, divided, lobate, lobed, parted, partite, segmented).
cyathiate architecture inflorescence Comprising one or more cyathia.
cyathiform solid shape perianth, calyx, corolla, pappus Having a cupulate tube and an indistinct, erect limb. See also cotyliform, urceolate (urn-shaped).
cyathium pl. cyathia nominative inflorescence Resembling a single flower, the unbranched axis very short with a terminal pistillate flower and several lateral staminate flowers, the whole subtended and to some degree enclosed by a cupulate envelope of bracts, the flowers diminutive and presumed to be evolutionarily reduced; characteristic of Euphorbia.
cycle = series, verticil, whorl STRUCTURE A set of three or more lateral structures that are inserted around an axis at the same level.
…cyclic = …seriate, …verticillate, …whorled arrangement Disposed in the number of cycles (series, verticils, whorls) indicated by the prefix; as in monocyclic, 3-cyclic.
cyclic = seriate, verticillate, whorled arrangement Disposed along the axis in groups of three or more, the members of each group (cycle, series, verticil, whorl) inserted around the axis at the same level.
cylindric(al) solid shape Solid and transversely round with a more or less uniform diameter, the ends blunt.
