|
segmented |
? cleft, dissected, divided, lobed, lobate, parted, partite |
solid shape |
|
Having two or more major component sectors or peripheral protrusions that are delimited by concavities in the surface or margin and that 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). |

solid shape |
perianth, calyx, corolla |

= urn-shaped |
solid shape |
perianth, calyx, corolla |
Having a truncate-ellipsoid tube and a distinct, erect limb, the whole somewhat constricted between tube and limb. See also cotyliform, cyathiform. |
|
divided |
