|
craspedodromous, mixed- |
|
venation |

|
creeping |

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. |
|
crenate |
= scalloped |
margin |
|
Having regularly alternating, rounded convexities and concavities oriented more or less perpendicular to the generalized perimeter. See also crenulate (small-scalloped), dentate, denticulate (small-toothed), serrate (sawtoothed), serrulate (small-sawtoothed). |
|
crenulate |
= small-scalloped |
margin |
|
Finely crenate (scalloped). See also dentate (toothed), denticulate (small-toothed), serrate (sawtoothed), serrulate (small-sawtoothed). |
|
crenule |
= scalloplet |
FEATURE |
|
A diminutive crena (scallop). See also dens (tooth), sawtooth, sawtoothlet, toothlet. |
|
crescent-shaped |
= lunate |
plane shape |
|
Arcuate, broadest at the middle, and attenuate to acute ends; like the stylized outline of a first-quarter moon. |
|
crest |
= crista |
STRUCTURE |
|
A laterally elongate, relatively thin, irregular or notched, apical protrusion. |
|
crested |
= cristate |
apex |
|
Having a laterally elongate, relatively thin, irregular or notched protrusion. |
|
crispate |
= crisped, curly |
margin |
|
Having closely and irregularly spaced, irregularly shaped, often compound convexities that curve irregularly through three dimensions. |
|
crisped |
= crispate, curly |
margin |
|
Having closely and irregularly spaced, irregularly shaped, often compound convexities that curve irregularly through three dimensions. |

architecture |
corolla, perianth |
Having four petals or tepals disposed in pairs of opposite members, the whole resembling a cross when viewed from above. |
|
cross-shaped 2 |
= cruciate |
solid shape |
|
Having two elongate, basically straight portions intersecting at a point interior to the ends of each. |
|
cross-vein |
|
STRUCTURE |
|
A relatively short, secondary or higher-order vein that runs directly between two veins of the next lower order, intersecting them more or less perpendicularly. |
|
crowded |
= compact, congested |
architecture |
|
Having equivalent constituent parts disposed very near to one another. |
