globular |
= globose, orbicular, rotund, spheric(al), spheroid(al) |
solid shape |
|
Uniformly convex, circular in any median section and in outline when viewed from any angle; like a globe or sphere. |
|
partite |
? cleft, dissected, divided, lobate, lobed, parted, segmented |
solid shape |
|
Having two or more component sectors or peripheral protrusions that are delimited by concavities in the surface or margin and that 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 protrusions 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). |

|
solid shape |
|
Divisible into essentially equal halves along one or more lines or planes. |
|
obcordiform |
|
solid shape |
|
Inversely cordiform (heart-shaped). |
|
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. |
|
thread-like |
= filiform |
solid shape |
|
Elongate and very slender, basically round in transverse section and of more or less uniform diameter, variously curved over its length or not. See also hair-like (capillary, capillate). |
|
circinate 1 |
|
solid shape |
|
Terete and rolled downward from the apex in a tight coil. |
|
feather-shaped |
= plumose |
solid shape |
|
Having a slender central axis bearing two opposite ranks of numerous, closely proximate, ascending, very slender branches or appendages; resembling the generalized form of a feather. |
|
prismatic |
|
solid shape |
|
Uniformly polygonal in transverse section, basally and apically truncate, all faces essentially plane. |

|
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. |

solid shape |
|
Having the number of lobes, divisions or segments indicated by the prefix; as in tripartite. |
|
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). |
|
calceolate |
= slipper-shaped |
solid shape |
|
Relatively thin-walled with an essentially hollow interior that is open on one side at the broader end. |
