planoconcave |
|
solid shape |
|
Relatively thin with opposite broad faces, one plane and one concave. |
worm-shaped |
= vermiculate |
solid shape |
|
Basically cylindric, elongate, and slender with bluntly rounded ends, variously curved over its length. |
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. |
muscariform |
= broom-shaped, 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. |
lobate |
? cleft, dissected, divided, lobed, parted, partite, segmented |
solid shape |
|
Having one or more component sectors or peripheral protrusions that is/are delimited by concavities in the surface or margin and that is/are not proximally distinct from the remainder of the whole. The meanings of this term and its approximate synonyms sometimes have been supposed to differ according to the depth of the delimiting concavities relative to the midline or midpoint of the overall structure, and/or to the shape or proportions of the protusions or sectors; however, there has been little consistency in the applications of the various terms according to such distinctions, which are ones only of degree and are necessarily arbitrary in any case. In general usage, these terms differ only indistinctly and connotatively: cleft, lobed (or lobate), parted (or partite) and segmented tend to connote fewer protrusions or sectors; lobate usually connotes as well a generally rounded shape; dissected tends to connote more numerous sectors that are elongate and angular. See also cut (incised, lacerate, torn), laciniate (slashed). |
fluted |
|
solid shape |
|
Having rounded to angular longitudinal grooves. |
coroniform |
= crown-shaped |
solid shape |
|
Shortly and broadly tubular overall, circumferentially continuous at the base, distally so or not; like a monarch's crown. |
planoconvex |
|
solid shape |
|
Relatively thin with opposite broad faces, one plane and one convex. |
disciform 1 |
= discoid |
solid shape |
|
Relatively thin with two round, plane or convex, opposite broad faces and a rounded circumferential edge; like a disc. See also lenticular (biconvex, lens-shaped), meniscoid, placentiform (placenta-shaped), trochlear (pulley-wheel-shaped). |
flanged |
|
solid shape |
|
Having a relatively broad circumferential rim or ridge that protrudes laterally. |
papillar(y) |
= papilliform |
solid shape |
|
Small, conoidal, and protruding from a larger structure; resembling a pimple; esp. trichomes. |
cuniculate |
|
solid shape |
elongate structure |
Hollow over a significant part of its length, the interior open at the end of the hollow portion. |
headless 2 |
= acephalous |
solid shape |
|
Not terminating in a head-like portion, esp. when one might be expected. |
pinnatifid |
> pinnatisect; < pinnate |
solid shape |
|
Pinnately divided. |
diamond-shaped |
= rhomboid |
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. |
scale-like |
= squamiform |
solid shape |
|
Isodiametric to elongate in broad outline, relatively very thin, and planate to moderately concave-convex. |
S-shaped 2 |
= sigmoid |
solid shape |
|
Elongate with more or less constant width or diameter and curved more or less regularly first in one direction and then in the opposite direction, like the letter S. |
mushroom-shaped |
= fungiform |
solid shape |
|
Having a cylindric base and a considerably broader, pulvinate distal portion; like the generalized form of a mushroom. |
…lobate |
? …cleft, …fid, …lobed, …parted, …partite, …segmented |
solid shape |
|
Having the number of lobes indicated by the prefix; as in bilobate. |
moniliform |
= beaded |
solid shape |
|
Elongate, relatively slender, transversely round, and more or less regularly constricted over its length, the whole straight or variously curved; like a necklace of beads. |
goblet-shaped |
= crateriform |
solid shape |
|
Having a distal, concave, relatively thin-walled, basically hemispherical portion surmounting a much narrower, transversely round, pedestal-like base. |
conoidal |
|
solid shape |
|
Generally but not strictly conic. |
flask-shaped |
= ampulliform, lageniform |
solid shape |
|
