|
inflated |
|
solid shape |
|
Relatively thin-walled with an essentially empty interior largely enclosed by the walls, which are convex overall and appear taut, as though from internal pressure. See also swollen (turgid, tumid), which is not clearly distinct in its application. |

planoconvex |
|
solid shape |
|
Relatively thin with opposite broad faces, one plane and one convex. |
|
flagelliform |
= whip-like |
solid shape |
|
Very slender, terete, generally straight, and apparently supple. |
|
lancehead-shaped 2 |
= lanceoloid, 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). |
|
turnip-shaped |
= napiform |
solid shape |
|
Depressed-globose overall and strongly concave-tapered (acuminate) at the base; like the generalized form of a turnip. |
|
annular |
= ring-shaped |
solid shape |
|
More or less evenly tubular in a closed circle; like a ring or doughnut. |
|
pulvinate 2 |
= cushion-shaped, mound-shaped, pulviniform |
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. |
|
triquetrous |
= three-angled, trigonous; > deltoid, obdeltoid |
solid shape |
|
Elongate with three sides that meet at acute or obtuse angles. |
|
subspheroid(al) |
= subglobose, suborbicular, subrotund, subspheric(al) |
solid shape |
|
Broadly ellipsoid with a length:width ratio closely approaching 1:1; almost spheroid(al), slightly longer than broad. |
|
lingulate |
= tongue-shaped |
solid shape |
|
Broadly elongate and compressed, one broad face more or less plane and the other convex, the edges rounded between them; like a tongue. |
|
mammiform |
= breast-shaped |
solid shape |
|
Rounded conic, like the breast of a mammal. |
|
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). |
|
dilate(d) |
|
solid shape |
elongate structure |
Narrow at one end and broadening toward the other; esp. when essentially terete at the narrow proximal end and seemingly flattened distally, as some anther filaments. |
