Basically circular in transverse section, broadest toward one end, attenuate toward and much narrower at the other, both ends rounded; slenderly turbinate or obturbinate; like a pear. |
globular |

partite |
? cleft, dissected, divided, lobate, lobed, parted, segmented |
solid shape |
|
Having two or more 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 protrusions 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 |
|
Convex or compressed-convex overall with a distal peak or ridge, relatively thin-walled and essentially hollow with the interior open to one side below the distal portion; resembling a hood or cowl. See also galeate (galeiform, helmet-shaped), which overlaps conceptually. |
flagelliform |

solid shape |
|

lanceoloid |
= lancehead-shaped, lanciform |
solid shape |
|
Considerably longer than broad, compressed or not, broadest near the base and somewhat concavely attenuate to the apex, the attenuation in all median longitudinal planes or else largely confined to one, depending upon the extent of compression, if any. See also oblanceoloid (oblanciform). |
subrotund |
= subglobose, suborbicular, subspheric(al), subspheroid(al) |
solid shape |
|
Broadly ellipsoid with a length:width ratio closely approaching 1:1; almost rotund, slightly longer than broad. |
kneed |

? …cleft, …fid, …lobate, …lobed, …parted, …segmented |
solid shape |
|
Having the number of lobes, divisions or segments indicated by the prefix; as in tripartite. |
conic(al) |
= cone-shaped |
solid shape |
|
Transversely round, essentially triangular in median longitudinal section, and broadest proximally. See also obconic(al). |
broom-shaped |
= muscariform, penicillate |
solid shape |
|
Having a proximal axis that bears a distal cluster of elongate slender branches or appendages, these variously ascending to erect; like a broom. |
lenticular 2 |
= biconvex, lens-shaped |
solid shape |
|
Relatively thin with two round, convex, opposite broad faces intersecting acutely at the circumferential edge; like a double-convex lens. See also disciform (discoid), meniscoid. |
cuculliform |
= cucullate, hood-shaped |
solid shape |
|
Convex or compressed-convex overall with a distal peak or ridge, relatively thin-walled and essentially hollow with the interior open to one side below the distal portion; resembling a hood or cowl. See also galeiform (galeate, helmet-shaped), which overlaps conceptually. |
scutate |
= buckler-shaped, scutiform |
solid shape |
|
Relatively thin with opposite broad oblong faces, planate to shallowly concave-convex, sometimes thickened about the periphery such that each face has a marginal rim; like an oblong shield. See also scutellate (platter-shaped, scutelliform), which is not clearly distinct in its application. |
urceolate |
