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). |

Having functional reproductive structures of both sexes. See also perfect. |

|
flabellate |
= fan-shaped, flabelliform |
solid shape |

laminar 2 |
|
solid shape |
|
Relatively very thin with parallel opposite broad faces, the whole plane or variously curved. Structures to which this term, along with any other three-dimensional ones, is applicable are often also described as though only two-dimensional, using terms that are implicitly understood to refer only to the outline of the broad faces. |

|
Mode or progressive pattern of bearing capitula (heads); most appropriately described using adjectival terms; esp. in Asteraceae (Compositae). |
|
orbicular |
= globose, globular, rotund, spheric(al), spheroid(al) |
solid shape |
|
Uniformly convex, circular in any median section and in outline when viewed from any angle; like a sphere or globe. |
|

STRUCTURE |
|
A prominent single tuft of relatively long and slender, flexible, capillate trichomes; esp. from a seed, as in Asclepias (Asclepiadaceae). |

solid shape |
|
Discoid (disciform) but with the circumferential surface concave between faces. |
|
rostellum 2 pl. rostella |
