|
mound-shaped |
= cushion-shaped, pulvinate, 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. |
|
carinate |
= keeled |
solid shape |
|
Having an elongate median longitudinal ridge that is basically triangular in transverse section, resembling the keel of a boat; esp. a leaf blade or sheath, glume, lemma, palea, sepal or petal. |
|
cymbiform |
= boat-shaped, 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. |
|
knobby |
= knotty, nodose |
solid shape |
|
Having knob-shaped (gongylodate, gongyloid, knot-shaped, nodiform) protrusions. See also nodulose. |
|
dolabrate |
= axehead-shaped |
solid shape |
|
Like an axehead oriented cutting edge downward. This term is not semantically distinct from dolabriform, but botanically they have had somewhat different applications. |
|
rhomboid |
= diamond-shaped |
solid shape |
|
Transversely square, broadest and longitudinally angular at the middle, regularly attenuate to angular ends, all faces essentially plane; like the stylized shape of a diamond. |
|
broom-shaped |
= muscariform, penicillate |
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. |
|
pear-shaped |
= pyriform |
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. |
|
spheric(al) |
= globose, globular, orbicular, rotund, spheroid(al) |
solid shape |
|
Uniformly convex, circular in any median section and in outline when viewed from any angle; like a sphere or globe. |
|
strombuliform |
= spire-shaped |
solid shape |
|
Attenuate-spiral in three dimensions, the coils contiguous or not. |
|
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. |
|
scrotiform |
= scrotum-shaped |
solid shape |
|
Saccate (bag-, pouch- or sack-shaped) and somewhat swollen bilaterally in the distal portion; like a scrotum. |
