cuboid |
|
solid shape |
|
Generally but not strictly cubic; more or less equilaterally six-sided, each side basically square. |
|
ring-shaped |
= annular |
solid shape |
|
More or less evenly tubular in a closed circle; like a ring or doughnut. |
|
scutiform |
= buckler-shaped, scutate |
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. |
|
umbilicate |
|
solid shape |
|
Having a relatively small, transversely round, central depression in an essentially round broad face. |
|
corniform |
= horn-shaped |
solid shape |
|
Straight or curved and slenderly conic or conoidal, like an animal horn. |
|
knotted |
= torulose |
solid shape |
|
Elongate and irregularly round in transverse section with narrow irregular constrictions and intervening, closely proximate gongyloid sectors, the whole straight or variously curved; serially gongyloid; like a sequentially knotted rope. |
|
tubercular |
= tuberculose |
solid shape |
|
Comprising small knot-like segments. |
|
ventricose |
= bellied |
solid shape |
|
Bulging unilaterally near the middle, as though with a belly. |
|
canaliculate |
= channeled |
solid shape |
|
Having a longitudinal, transversely rounded depression; esp. a petiole or petiolule. |
|
placentiform |
= placenta-shaped |
solid shape |
|
Thickly disciform (discoid); like the generalized shape of a human placenta. |
|
oblanceoloid |
= oblanciform |
solid shape |
|
Inversely lanceoloid (lancehead-shaped, lanciform). |
|
annular |
= ring-shaped |
solid shape |
|
More or less evenly tubular in a closed circle; like a ring or doughnut. |
|
slipper-shaped |
= calceolate |
solid shape |
|
Relatively thin-walled with an essentially hollow interior that is open on one side at the broader end. |
|
head-shaped |
= capitate, capitiform |
solid shape |
|
Basically globose and resembling a head in the context of occurrence. |
|
awl-shaped 2 |
= subulate |
solid shape |
|
Slender, essentially terete, and straight, gradually attenuate from a relatively narrow base to a very narrow, blunt to angular apex. |
|
cleft |
? dissected, divided, lobate, lobed, parted, partite, segmented |
solid shape |
|
Having two or more component sectors or peripheral protrusions that are delimited by concavities in the margin or surface 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). |
