= dome-shaped |
solid shape |
|
Convex overall, broadest at the base, and transversely more or less circular to elliptical throughout. |
sawtoothed |

margin |
|
Having regularly spaced, angular convexities oriented at an acute angle to the generalized perimeter. See also scalloped (crenate), small-scalloped (crenulate), small-sawtoothed (serrulate), small-toothed (denticulate), toothed (dentate). |
appendage |
|
STRUCTURE |
|
Any subordinate structure ontogenetically derived from and associated with a given organ or part. |
