solid shape |
|
Isodiametric to elongate in broad outline, relatively very thin, and planate to moderately concave-convex. |
snail-shell-shaped |
= cochleate |
solid shape |
|
Relatively broad and short, basically round in transverse section, resembling a rapidly tapering spire overall, the exterior helically convoluted. |
umbraculiform |
= umbrella-shaped |
solid shape |
|
Having a slender, elongate proximal axis and a very broad, meniscoid distal portion, the latter oriented with its convex face distal; like an umbrella. |
pyriform |
= pear-shaped |
solid shape |
|
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. |
ellipsoid(al) |
|
solid shape |
|
Elliptic in any median longitudinal section; elongate, transversely circular, broadest at the middle, and symmetrically convex-attenuate to rounded ends. See also oblong. |
horseshoe-shaped |
= hippocrepiform |
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. |
tuberculose 2 |
= tubercular |
solid shape |
|
Comprising small knot-like segments. |
mitre-shaped |
= mitriform |
solid shape |
|
Broadest and transversely round to oval proximally, tapering bilaterally above the middle to a central peak; like a peaked hat or cap. |
canaliculate |
= channeled |
solid shape |
|
Having a longitudinal, transversely rounded depression; esp. a petiole or petiolule. |
bulliform |
|
solid shape |
|
Resembling a blister; broad, relatively thin at the periphery, the lower surface approximately flat, the upper shallowly to strongly convex. |
penicillate |
= broom-shaped, muscariform |
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. |
umbrella-shaped |
= umbraculiform |
solid shape |
|
Having a slender, elongate proximal axis and a very broad, meniscoid distal portion, the latter oriented with its convex face distal; like an umbrella. |
biconvex 2 |
= lens-shaped, lenticular |
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. |
cone-shaped |
= conic(al) |
solid shape |
|
Transversely round, essentially triangular in median longitudinal section, and broadest proximally. See also obconic(al). |
S-shaped 2 |
= sigmoid |
solid shape |
|
