|
pleated 1 |
= plaited, plicate |
solid shape |
foliaceous structure |
Having alternately adaxial and abaxial lengthwise folds, resembling a fan. |
|
depressed |
< flattened |
solid shape |
|
Flattened distally, perpendicular to the longitudinal axis, as though pressed from the top, the external surface otherwise basically convex. Often used in combination with some other term that describes the overall shape exclusive of ("before") flattening, e.g., depressed-globose. See also compressed (complanate), obcompressed. |
|
flanged |
|
solid shape |
|
Having a relatively broad circumferential rim or ridge that protrudes laterally. |
|
taeniate |
= tapeworm-shaped |
solid shape |
|
Slender, elongate, basically cylindric or compressed-cylindric with shallow, narrow, more or less regular constrictions along its length, the whole apparently segmented and straight or variously curved. |
|
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. |
|
scrotiform |
= scrotum-shaped |
solid shape |
|
Saccate (bag-, pouch- or sack-shaped) and somewhat swollen bilaterally in the distal portion; like a scrotum. |
|
spheroid(al) |
= globose, globular, orbicular, rotund, spheric(al) |
solid shape |
|
Uniformly convex, circular in any median section and in outline when viewed from any angle; like a sphere or globe. |
|
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. |
|
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. |
