|
club-shaped |
= clavate |
solid shape |

|
beaded |
= moniliform |
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. |
|
peripterous |
|
solid shape |
|
Alate with a single transversely encircling wing. |
|
lacrimiform |
= teardrop-shaped |
solid shape |
|
Transversely round and broadest just below the middle, broadly rounded to the base and acutely attenuate to the apex. |
|
saccate 2 |
= bag-shaped, pouch-shaped, sack-shaped |
solid shape |
|
Irregularly obovoid with an exterior aspect intermediate between inflated and flaccid; like a closed pouch or bag. |
|
hair-like |
= capillary, capillate |
solid shape |
|
Finely filiform; resembling a hair. |
|
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. |
|
tubular |
|
solid shape |
|
Cylindric or attenuate-cylindric overall and with a hollow interior open at one or both ends. |
|
gongylodate |
= gongyloid, knob-shaped, 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. |
|
cup-shaped |
= calyciform, cupulate |
solid shape |
|
Truncate-globose with the distal margin more or less entire; like the bowl of a cup. |
|
platter-shaped |
= scutellate, scutelliform |
solid shape |
|
Relatively thin with opposite broad oval faces, shallowly concave-convex; like a serving platter. See also buckler-shaped (scutate, scutiform), which is not clearly distinct in its application. |
|
oblong 2 |
|
solid shape |
|
Compressed-ellipsoid, the sides approximately parallel from near one end to near the other. See also ellipsoid(al). |
|
hippocrepiform |
= horseshoe-shaped |
solid shape |
|
Relatively slender and strongly compressed, the whole strongly curved over its length in a plane perpendicular to the direction of compression and forming an incomplete circle, the ends somewhat straighter than the rest and parallel or nearly so; like a horseshoe. |
|
complanate |
= compressed; < flattened |
solid shape |
|
Flattened bilaterally, parallel to the longitudinal axis, as though pressed or squeezed from opposing sides, the external surface otherwise basically convex. This term usually implies a strong degree of flattening. See also depressed, obcompressed. |
|
heart-shaped 3 |
= cordiform |
solid shape |
