|
breast-shaped |
= mammiform |
solid shape |
|
Rounded conic, like the breast of a mammal. |
|
parted |
? cleft, dissected, divided, lobate, lobed, 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 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). |

checkered 2 |
= tessellate |
relief |
|
Having a pattern of regularly disposed squares marked by raised or depressed vasculature. |
|
corrugate 1 |
= crumpled |
aestivation |
|
Having members tightly and irregularly folded, the whole appearing as though wadded upon emergence. |
|
receptacular |
|
position |
|
Upon, arising from, or otherwise directly associated with the receptacle. |
|
diffuse root |
> fibrous root |
STRUCTURE |
|
Any member of a dense system of adventitious, slender roots that arise from the base of a main stem and functionally replace an evanescent primary root. |
|
flower |
|
STRUCTURE |
|
A functionally integrated, complex structure comprising sets of sporophytic and/or associated sterile structures disposed in standard sequence along a common axis; consisting of one or more constituent members each of, in ascending (proximal to distal) order of insertion, perianth (tepals, or else sepals and/or petals), androecium (stamens, staminodes and/or other associated structures), and/or gynoecium (pistils and/or other associated structures), the foregoing all borne laterally from the distal portion (receptacle) of the axis; depending upon the combination of structures present, may be bisexual, staminate only, pistillate only, or sterile; characteristic of and unique to the Magnoliophyta (Angiospermae). When a fertile androecium and gynoecium are both present a flower is termed perfect. When perfect and also with calyx and corolla both present, a flower is termed complete. Both terms are somewhat archaic and of limited descriptive value. |

STRUCTURE |
|
The narrow portion of a structure that is notably constricted. |
|

coloration |
|
Having an overall pattern of fine, more or less parallel, lines of contrasting hue and/or intensity. |
|

|
leftward |

orientation |
|
Directed to the left, relative to the direction of growth along an explicit or implicit axis of reference. See also rightward (dextrorse). |
|
accessory cell |
|
STRUCTURE |
|
One of the cytologically distinctive epidermal cells that are sometimes present in a stomate and that surround and are regularly oriented in relation to the guard cells. |
|
lobe |
? division, segment |
STRUCTURE |
|
Any generally convex, major peripheral protrusion or component sector that is delimited by concavities in the surface or margin and that is not proximally distinct from the remainder of the whole. |
|
napiform |
= turnip-shaped |
solid shape |
|
Depressed-globose overall and strongly acuminate (concave-tapered) at the base; like the generalized form of a turnip. |
|
birettaform |
|
solid shape |
|

|
caudicle |
= translator arm |
STRUCTURE |
|
An attenuate end portion by which a pollinium adheres to a pollinating insect, either directly or by means of a terminal viscidium, the latter, when present, sometimes attached by an intervening stipe; esp. in Asclepiadaceae, Orchidaceae. |
