Transversely round, essentially triangular in median longitudinal section, and broadest proximally. See also obconic(al). |
|
saddle-shaped |
= selliform |
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. |

solid shape |
|
Uniformly polygonal in transverse section, basally and apically truncate, all faces essentially plane. |
|
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). |
|
suborbicular |
= subglobose, subrotund, subspheric(al), subspheroid(al) |
solid shape |
|
Broadly ellipsoid with a length:width ratio closely approaching 1:1; almost orbicular, slightly longer than broad. |
|
liguliform |
= lorate, strap-shaped |
solid shape |
|
Elongate and relatively thin with the opposite faces more or less plane and moderately narrow, their edges more or less straight and parallel over most of their length; resembling a strap. |
|
nodulose |
|
solid shape |
|
Diminutively nodose; esp. roots of Fabaceae (Leguminosae), the nodules harboring nitrogen-fixing bacteria. |
|
capillate |
= capillary, hair-like |
solid shape |
|
Finely filiform; like a hair. |
|
cupulate |
= calyciform, cup-shaped |
solid shape |
|
Truncate-globose with the distal margin more or less entire; like the bowl of a cup. |
|
obterete |
|
solid shape |
|
Inversely terete. |
|
channeled |
= canaliculate |
solid shape |
|
Having a longitudinal, transversely rounded depression; esp. a petiole or petiolule. |
|
bifurcate |
< forked, furcate |
solid shape |
|
Having two terminal, antrorse branches or divisions arising from a common point or level, like the prongs of a fork. |
|
fistulose |
|
solid shape |
|
Basically tubular with closed ends. |
|
hippocrepiform |
= horseshoe-shaped |
solid shape |
|
Relatively slender and strongly compressed, the whole strongly curved over its length in a plane perpendicular to the direction of compression and forming an incomplete circle, the ends somewhat straighter than the rest and parallel or nearly so; like a horseshoe. |
|
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). |
