solid shape |
|
Elongate, slender, terete, straight, terminating in a fine point, and apparently stiff. |
|
scimitar-shaped |
= acinaciform |
solid shape |
|
Thin and moderately arcuate with two opposite, plane, broad faces, the degree of curvature increasing distally, thinnest at the convex edge, thicker toward the concave; like a scimitar blade. |
|
fluted |
|
solid shape |
|
Having rounded to angular longitudinal grooves. |
|
lens-shaped 2 |
= biconvex, lenticular |
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. |
|
acephalous 2 |
= headless |
solid shape |
|
Not terminating in a head-like portion, esp. when one might be expected. |
|
…lobed |
? …cleft, …fid, …lobate, …parted, …partite, …segmented |
solid shape |
|
Having the number of lobes indicated by the prefix; as in five-lobed. |
|
planoconvex |
|
solid shape |
|
Relatively thin with opposite broad faces, one plane and one convex. |
|
flagelliform |
= whip-like |
solid shape |
|
Very slender, terete, generally straight, and apparently supple. |
|
turnip-shaped |
= napiform |
solid shape |
|
Depressed-globose overall and strongly concave-tapered (acuminate) at the base; like the generalized form of a turnip. |
|
lancehead-shaped 2 |
= lanceoloid, 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). |
|
annular |
= ring-shaped |
solid shape |
|
More or less evenly tubular in a closed circle; like a ring or doughnut. |
|
pulvinate 2 |
= cushion-shaped, mound-shaped, 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. |
|
triquetrous |
