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). |

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-lipped |
= syndetocheilic |
architecture |
stomate |
Having subsidiary cells derived from the primary stoma mother cell and thus immediately related ontogenetically to the guard cells. |
|
compressed |
= complanate; < flattened |
solid shape |
|
Flattened bilaterally, parallel to the longitudinal axis, as though pressed or squeezed from opposing sides, the external surface otherwise basically convex. Used alone, this term usually implies a strong degree of flattening; otherwise, it is often used in combination with some other term that describes the overall shape exclusive of ("before") flattening, e.g., compressed-ovoid. See also depressed, obcompressed. |
|
concave-tapered 1 |
= acuminate |
apex |
|
Gradually diminishing in width or diameter to a slender tip, the sides longitudinally concave. Corresponds with attenuate for base shape. |
|
concave-tapered 2 |
= attenuate |
base |
|
Gradually diminishing in width or diameter toward the proximal end, the sides longitudinally concave. Corresponds with acuminate for apex shape. |
|
concentric |
|
position |
|
Having a center or axis of symmetry coincident with that of the context of reference. |
|
concolor(ous) |
|
coloration |
|
Uniform in hue and intensity of color; esp. leaves with identically colored adaxial and abaxial surfaces. |
|
conduplicate 1 |
= duplicate |
arrangement |
cotyledons |
Adaxially contiguous, folded sharply together longitudinally (one adaxially, one abaxially), and reflexed together, one enveloping the hypocotyl and radicle, the other enveloping the first. |
|
conduplicate 2 |
= duplicate |
vernation |
|
Each leaf folded sharply inward along its longitudinal axis, the adaxial surfaces of each side facing one another. |
|
cone |
= strobilus; > female cone, macrostrobilus (not recommended), male cone, megastrobilus, microstrobilus |
STRUCTURE |
|
A compound or complex reproductive structure consisting of a central axis bearing congested imbricate sporophylls and sometimes also sterile bracts. |
|
cone scale |
< macrosporophyll (not recommended), megasporophyll, microsporophyll; > ovuliferous scale |
STRUCTURE |
|
One of the membranous, fleshy, or woody sporophylls of a cone (strobilus); esp. in Pinophyta. |
|
cone-shaped |
= conic(al) |
apex |
|
Transversely round, essentially triangular in median longitudinal section, and broadest proximally. See also obconic(al). |
|

= conic(al) |
