turbinate |

|
sellaeform |

|
lobed |
? cleft, dissected, divided, lobate, parted, partite, segmented |
solid 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). |
|
palmatifid |
|
solid shape |
|
Palmately lobate; having three or more lobes whose longitudinal axes radiate from a common point. |
|
gongyloid |
= gongylodate, knob-shaped, knot-shaped, nodiform |
solid shape |
|
Approximately globose, the surface convoluted or not, like a knob or knot; usually applied only to structures or components that are relatively small. |
|
turgid |
= swollen, tumid |
solid shape |
|
Engorged in appearance, convex overall with the surface appearing taut, as though from internal pressure. See also inflated, which is not clearly distinct in its application. |
|
cyathiform |
|
solid shape |
perianth, calyx, corolla, pappus |
Having a cupulate tube and an indistinct, erect limb. See also cotyliform, urceolate (urn-shaped). |
|
setaceous |
= bristle-shaped, setiform |
solid shape |
|

|
axehead-shaped |
= dolabrate |
solid shape |
|
Like an axe head oriented cutting edge downward. |
|
meniscoid |
|
solid shape |
|
Relatively thin with opposite, round, broad faces, one convex and one concave (as viewed externally), the circumferential edge angular or rounded; like a meniscus. See also discoid (disciform), lenticular (biconvex, lens-shaped), patelliform (kneecap-shaped). |
