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. |
…partite |
? …cleft, …fid, …lobate, …lobed, …parted, …segmented |
solid shape |
|
Having the number of lobes, divisions or segments indicated by the prefix; as in tripartite. |
conoidal |
|
solid shape |
|
Generally but not strictly conic. |
lenticular 2 |
= biconvex, lens-shaped |
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. |
scutate |
= buckler-shaped, 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 scutellate (platter-shaped, scutelliform), which is not clearly distinct in its application. |
urceolate |
= urn-shaped |
solid shape |
perianth, calyx, corolla |
Having a truncate-ellipsoid tube and a distinct, erect limb, the whole somewhat constricted between tube and limb. See also cotyliform, cyathiform. |
lanceoloid |
= lancehead-shaped, lanciform |
solid shape |
|
Considerably longer than broad, compressed or not, broadest near the base and somewhat concavely attenuate to the apex, the attenuation in all median longitudinal planes or else largely confined to one, depending upon the extent of compression, if any. See also oblanceoloid (oblanciform). |
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. |
subrotund |
= subglobose, suborbicular, subspheric(al), subspheroid(al) |
solid shape |
|
Broadly ellipsoid with a length:width ratio closely approaching 1:1; almost rotund, slightly longer than broad. |
kneed |
= geniculate |
solid shape |
|
Elongate, abruptly bent, somewhat thicker at the angle, and appearing as though articulate like a leg at the knee. |
teardrop-shaped 2 |
= lacrimiform |
solid shape |
|
Transversely round and broadest just below the middle, broadly rounded to the base and acutely attenuate to the apex. |
semiobterete |
= half-obterete |
solid shape |
|
Inversely semiterete; obterete but flattened on one side. |
dome-shaped |
= tholiform |
solid shape |
|
Convex overall, broadest at the base, and transversely more or less circular to elliptical throughout. |
patelliform |
= kneecap-shaped |
solid shape |
|
Thickly meniscoid, like a human kneecap. |
obdeltoid |
< three-angled, trigonous, triquetrous |
solid shape |
|
Three-angled (trigonous, triquetrous), broadest distally, and regularly attenuate to an angular base; inversely deltoid. |
flabellate |
= fan-shaped, flabelliform |
solid shape |
|
Strongly compressed, broadest near the apex and attenuate to a narrow base, plaited longitudinally, the alternating folds radiating from the base, the whole basically triangular in broad aspect; like a partially expanded folding fan. |
scutellate |
= platter-shaped, scutelliform |
solid shape |
|
Relatively thin with opposite broad oval faces, shallowly concave-convex; like a serving platter. See also scutate (buckler-shaped, scutiform), which is not clearly distinct in its application. |
lanciform |
= lancehead-shaped, lanceoloid |
solid shape |
|
Considerably longer than broad, compressed or not, broadest near the base and somewhat concavely attenuate to the apex, the attenuation in all median longitudinal planes or else largely confined to one, depending upon the extent of compression, if any. See also oblanciform (oblanceoloid). |
ear-shaped |
= auriform |
solid shape |
|
Resembling a mammalian outer ear. |
knob-shaped |
= gongylodate, gongyloid, knot-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. |
waisted |
|
solid shape |
|
Constricted in width or breadth at or near the middle of its length. |
club-shaped |
= clavate |
solid shape |
|
Elongate and basically round in transverse section, the diameter greatest at or near a blunt apex, thence attenuate toward the base, the degree of taper greatest between the middle and the upper quarter. |
semiterete |
= half-terete |
solid shape |
|
Terete but flattened on one side. |
horn-shaped |
= corniform |
solid shape |
|
Straight or curved and slenderly conic or conoidal, like an animal horn. |
placenta-shaped |
= placentiform |
solid shape |
|
Thickly discoid (disciform); like the generalized form of a human placenta. |
