Circular in cross-section, inflated proximally, thence broadening gradually to a flared distal portion. |

gibbous |

Bulging unilaterally near the base. |
|
cushion-shaped |
= mound-shaped, pulvinate, pulviniform |
solid shape |

testicular |

solid shape |
|
Bilaterally symmetrical, each side essentially oblate and constrictedly confluent with the other; like the overall shape of a pair of mammalian testes. |
|
flattened |

Convex overall but with one or more sides or ends distinctly deviating toward plane, as though pressed or squeezed there. |
|
pouch-shaped |
= bag-shaped, saccate, sack-shaped |
solid shape |
|
Irregularly obovoid with an exterior aspect intermediate between inflated and flaccid; like a closed pouch or bag. |
|
trochlear |

solid shape |
|
Discoid (disciform) but with the circumferential surface concave between faces. |
|
segmented |
? cleft, dissected, divided, lobed, lobate, parted, partite |
solid shape |
|
Having two or more major 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 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). |
|
bellied |
= ventricose |
solid shape |
|
Bulging unilaterally near the middle, as though with a belly. |
|
conic(al) |

|
Transversely round, essentially triangular in median longitudinal section, and broadest proximally. See also obconic(al). |
|
ampulliform |
= flask-shaped, lageniform |
solid shape |
|
Generally circular in cross-section, broadest at or below the middle, approximately globose below that and constricted above to a relatively narrow neck; like a flask. |
|
falcate 2 |
= sickle-shaped |
solid shape |
|
Elongate, strongly compressed, and arcuate in the plane of compression, the two faces more or less plane and parallel, the degree of curvature decreasing distally or not; like a sickle blade. |
|
top-shaped |
= turbinate |
solid shape |
|
Broadly obovoid-obconic; like a spinning top. See also pear-shaped (pyriform), obturbinate. |
|
subulate 2 |
= awl-shaped |
solid shape |
|
Slender, essentially terete, and straight, gradually attenuate from a relatively narrow base to a very narrow, blunt to angular apex. |
|
lageniform |

perianth, calyx, corolla |
Having a relatively long, slender tube and a divaricate, planate limb resembling a round platter. |
|
dissected |
? cleft, divided, lobate, lobed, parted, partite, 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 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). |

turbinate |
