acicular 2 |
= acerose, needle-shaped |
solid shape |
|
Rounded in cross-section and very slenderly elongate, broadest near the middle, and gradually attenuate to an acute apex and a slightly blunter base; like a needle. |
|
boat-shaped |
= cymbiform, navicular |
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. |
|
ensiform |
= sword-shaped |
solid shape |
|
Elongate and moderately slender, strongly compressed, the opposite faces plane, parallel, broadest at the base and gradually attenuate to a short, more strongly attenuate, acute apex; like a broadsword blade. |
|
flask-shaped |
= ampulliform, lageniform |
solid shape |
|
Generally circular in cross-section, broadest at or below the middle, approximately globose below that and constricted above to a relatively narrow neck; like a flask. |
|
cariniform |
= keel-shaped |
solid shape |
|
Elongate, basically triangular in transverse section, tapering at one or both ends, the outer edge thus somewhat arcuate, the whole resembling the keel of a boat. |
|
pinnatifid |
> pinnatisect; < pinnate |
solid shape |
|
Pinnately divided. |
|
knot-shaped |
= gongylodate, gongyloid, knob-shaped, nodiform |
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. |
|
cruciate 2 |
= cross-shaped |
solid shape |
|
Having two elongate, basically straight portions intersecting at a point interior to the ends of each. |
|
dolabriform |
= axe-shaped |
solid shape |
|
Elongate, basally terete, becoming strongly compressed toward an abruptly and unilaterally broader apex; like an axe (handle plus head). This term is not semantically distinct from dolabrate, but botanically they have had somewhat different applications. |
|
semiterete |
= half-terete |
solid shape |
|
Terete but flattened on one side. |
|
ascidiform |
= pitcher-shaped |
solid shape |
|
Having a more or less tubular, radially or bilaterally symmetrical body closed at the base and broadening toward a more or less open apex sometimes lidded or overarched by a prolongation of one side; like a pitcher. |
|
buckler-shaped |
= scutate, scutiform |
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 platter-shaped (scutellate, scutelliform), which is not clearly distinct in its application. |
|
obcordiform |
|
solid shape |
|
Inversely cordiform (heart-shaped). |
|
circinate 1 |
|
solid shape |
|
Terete and rolled downward from the apex in a tight coil. |
|
scrotum-shaped |
= scrotiform |
solid shape |
|
Saccate (bag-, pouch- or sack-shaped) and somewhat swollen bilaterally in the distal portion; like a scrotum. |
|
flattened |
> complanate, compressed, depressed, obcompressed |
solid shape |
|
Convex overall but with one or more sides or ends distinctly deviating toward plane, as though pressed or squeezed there. |
|
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. |
|
waisted |
|
solid shape |
|
Constricted in width or breadth at or near the middle of its length. |
|
bag-shaped |
= pouch-shaped, saccate, sack-shaped |
solid shape |
|
Irregularly obovoid with an exterior aspect intermediate between inflated and flaccid; like a closed pouch or bag. |
|
dome-shaped |
= tholiform |
solid shape |
|
Convex overall, broadest at the base, and transversely more or less circular to elliptical throughout. |
|
torulose |
= knotted |
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. |
|
acinaciform |
= scimitar-shaped |
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. |
|
slipper-shaped |
= calceolate |
solid shape |
|
Relatively thin-walled with an essentially hollow interior that is open on one side at the broader end. |
|
pinnatisect |
< pinnate, pinnatifid |
solid shape |
|
Pinnately divided with the sinuses extending to the central axis. |
|
egg-shaped 2 |
= ovoid |
solid shape |
|
Transversely circular, broadest near a bluntly rounded base, and convexly attenuate to a narrower rounded apex; like a fowl egg. See also obovoid. |
