solid shape |
|
Finely filiform; resembling a hair. |

An area that differs in color from the rest of a structure's surface, usually due to differing coloration. See also eyespot. |
|
decussate |
|
arrangement |
|
Opposite with successive pairs radially oriented at right angles to one another, thus polystichous with four equidistant ranks. |
|
pore |
|
FEATURE |
|
A small aperture or opening in a wall or covering that allows transport between interior and exterior. |
|
lobed |
? cleft, dissected, divided, lobate, parted, partite, segmented |
plane shape |
|
Having one or more component sectors or peripheral protrusions that is/are delimited by concavities in the surface or margin and that is/are not proximally distinct from the remainder of the whole. The meanings of this term and its approximate synonyms sometimes have been supposed to differ according to the depth of the delimiting concavities relative to the midline or midpoint of the overall structure, and/or to the shape or proportions of the protusions or sectors; however, there has been little consistency in the applications of the various terms according to such distinctions, which are ones only of degree and are necessarily arbitrary in any case. In general usage, these terms differ only indistinctly and connotatively: cleft, lobed (or lobate), parted (or partite) and segmented tend to connote fewer protrusions or sectors; lobate usually connotes as well a generally rounded shape; dissected tends to connote more numerous sectors that are elongate and angular. See also cut (incised, lacerate, torn), laciniate (slashed). |
