oblong 2 |
|
solid shape |
|
Compressed-ellipsoid, the sides approximately parallel from near one end to near the other. See also ellipsoid(al). |
|
sellaeform |
|
solid shape |
|
See selliform. |

placenta-shaped |

solid shape |
|
Thickly discoid (disciform); like the generalized form of a human placenta. |
|
napiform |
= turnip-shaped |
solid shape |
|
Depressed-globose overall and strongly acuminate (concave-tapered) at the base; like the generalized form of a turnip. |
|
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. |
|
star-shaped 2 |
= stellate |
solid shape |
|
Having a distal aspect like the stylized shape of a star; stipitate or sessile with elongate branches or appendages radiating widely in three dimensions from a common point at the apex of the proximal axis or, when sessile, upon the bearing surface. |
|
headed 2 |
= capitate |
solid shape |
|
Abruptly enlarged distally to a relatively short, terminal portion that is basically round in transverse section. |
|
thread-like |
= filiform |
solid shape |
|
Elongate and very slender, basically round in transverse section and of more or less uniform diameter, variously curved over its length or not. See also hair-like (capillary, capillate). |
|
dissected |
? cleft, divided, lobate, lobed, parted, partite, 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 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). |
|
pulviniform |
= cushion-shaped, mound-shaped, pulvinate |
solid shape |
|
Essentially round in transverse section, much broader than long or high, with a convex distal face that intersects either a more or less plane proximal face or, when the structure is sessile, its bearing surface. |
|
fluted |
|
solid shape |
|
Having rounded to angular longitudinal grooves. |
|
subglobose |
= suborbicular, subrotund, subspheric(al), subspheroid(al) |
solid shape |
|
Broadly ellipsoid with a length:width ratio closely approaching 1:1; almost globose, slightly longer than broad. |
|
selliform var. sellaeform |
= saddle-shaped |
solid shape |
|
Relatively thin, broad and long, strongly compound-curved, concavely from end to end and convexly from side to side; like the generalized shape of a saddle. |
|
waisted |
|
solid shape |
|
Constricted in width or breadth at or near the middle of its length. |
|
cross-shaped 2 |
= cruciate |
solid shape |
|
Having two elongate, basically straight portions intersecting at a point interior to the ends of each. |
|
symmetric(al) 1 |
|
solid shape |
|
Divisible into essentially equal halves along one or more lines or planes. |
|
navicular |
= boat-shaped, cymbiform |
solid shape |
|
Like the generalized form of a boat hull, the walls relatively thin to moderately thick, the interior essentially empty and open along one side. |
|
nodiform |
= gongylodate, gongyloid, knob-shaped, knot-shaped |
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. |
|
scimitar-shaped |
= acinaciform |
solid shape |
|
Thin and moderately arcuate with two opposite, plane, broad faces, the degree of curvature increasing distally, thinnest at the convex edge, thicker toward the concave; like a scimitar blade. |
|
urceolate |
= 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. |
|
falcate 2 |
= sickle-shaped |
solid shape |
|
Elongate, strongly compressed, and arcuate in the plane of compression, the two faces more or less plane and parallel, the degree of curvature decreasing distally or not; like a sickle blade. |
|
teardrop-shaped 2 |
= lacrimiform |
solid shape |
|
Transversely round and broadest just below the middle, broadly rounded to the base and acutely attenuate to the apex. |
|
squamiform |
