|
reniform 2 |

solid shape |
|
Thickly elongate and arcuate, circular or compressed-circular in transverse section, each end bluntly rounded; like the generalized shape of a human kidney. |

solid shape |
|
Thickly meniscoid, like a human kneecap. |
|
geniculate |

solid shape |
|
Elongate, abruptly bent, somewhat thicker at the angle, and appearing as though articulate like a leg at the knee. |
|
nodose |
= knobby, knotty |
solid shape |

Having nodiform (gongylodate, gongyloid, knob-shaped, knot-shaped) protrusions. See also nodulose. |
|
knotty |
= knobby, nodose |
solid shape |
|
Having knot-shaped (gongylodate, gongyloid, knob-shaped, nodiform) protrusions. See also nodulose. |
|
torulose |
= knotted |
solid shape |
|
Elongate and irregularly round in transverse section with narrow irregular constrictions and intervening, closely proximate gongyloid sectors, the whole straight or variously curved; serially gongyloid; like a sequentially knotted rope. |
|
knobby |
= knotty, nodose |
solid shape |
|
Having knob-shaped (gongylodate, gongyloid, knot-shaped, nodiform) protrusions. See also nodulose. |
|
lipped |
= labiate; > bilabiate, one-lipped, two-lipped, unilabiate |
architecture |
perianth, calyx, corolla |
Strongly zygomorphic with connate and/or coherent members some or all of whose distal portions form one or two lip-like structures. |
|
lip |
= labium; > labellum |
STRUCTURE |
|
Any substructure that resembles a lip, especially a portion of a perianth, calyx or corolla. |
|
slashed |
= laciniate; < cut, incised, lacerate, torn |
plane shape |
|
Having relatively close, more or less straight lines of separation exending inward from the margin. See also cleft (dissected, divided, lobate, lobed, parted, partite, segmented). |
|
teardrop-shaped 1 |
= lacrimate |
plane shape |
|
Broadest just below the middle, broadly rounded to the base, and acutely attenuate to the apex; like the stylized lateral outline of a teardrop. |
|
teardrop-shaped 2 |
= lacrimiform |
solid shape |
|
Transversely round and broadest just below the middle, broadly rounded to the base and acutely attenuate to the apex. |
|
scalariform |
= ladder-like |
arrangement |
|
Disposed in vertical sequence with long axes horizontal and parallel. |
|
glossy |
= laevigate, lustrous, polished, shining, shiny |
reflectance |
|
Uniformly reflecting a high proportion of incident light at all angles. |
|
blade |
= lamina |
STRUCTURE |
|
The expanded, more or less planate, distal portion, when present, of a leaf, leaflet or bract. |
|
ray 2 |
= lamina |
STRUCTURE |
|
The distal, relatively flat portion of the corolla of a ray floret, terminating in 0--4 teeth or lobes; in Asteraceae (Compositae). |
|
lanceolate |
= lancehead-shaped |
plane shape |
|
Elongate, moderately narrow, broadest just above the base and gradually attenuate toward the apex, the sides more or less straight; like the outline of the broad lateral face of a lance head. See also oblanceolate. |
|
lanciform |
= lancehead-shaped, lanceoloid |
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 oblanciform (oblanceoloid). |
