revolute 1 |
|
margin |
|
Rolled inward abaxially. |
|
segmented |
? cleft, dissected, divided, lobed, lobate, parted, partite |
plane 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). |

|
arillus pl. arilli |
= aril (strict sense); < aril (broad sense) |
STRUCTURE |
|
An appendicular structure that wholly or partly envelops a seed and is an outgrowth from the funicle or raphe, and thus is ontogenetically derived from the placenta; usually fleshy or pulpy, sometimes spongy or tufted-capillate, often brightly colored. |
|
macula pl. maculae |
= blotch, spot |
FEATURE |
|
An area that differs in color from the rest of a structure's surface, usually due to differing coloration. See also eyespot. |
|
chartaceous |
= papery, papyraceous |
texture |
|
Very thin, flexible, and readily torn; like paper. See also membranaceous (membranous), pergamentaceous (parchment-like). |
|
coronal |
|
insertion |
|
Upon or otherwise directly associated with the corona. |
|
receptacle 1 |
= torus |
STRUCTURE |
|
The relatively short, simple, axial structure surmounting a pedicel and basal to the flower, usually broader than the pedicel. |
|
epipetalous |
|
position |
|
Upon the petals, or partially adnate thereto and apparently arising therefrom. |
|
floret |
|
STRUCTURE |
|
A very small, structurally specialized flower, especially when occurring in capitulum (head; Asteraceae), or in a spikelet (Poaceae), where it includes the immediately subtending bracts (lemma and palea). |
|
gynostemium pl. gynostemia |
= column, gynandrium |
STRUCTURE |
|
A central floral structure consisting of the partly to wholly fused (connate and adnate) androecium and gynoecium; esp. in Orchidaceae. |
|
strap-shaped |
= liguliform, lorate |
solid shape |
|
Elongate and relatively thin with the opposite faces more or less plane and moderately narrow, their edges more or less straight and parallel over most of their length; resembling a strap. |
|
indument |
|
STRUCTURE / SUBSTANCE |
|
See indumentum. |
|
terminal |
|
position |
|
Apical and with the same developmental axis as the whole, of which it is the distalmost portion or appendage. |

= greasy, oily, oleaginous |
texture |
|
Liquid or deformably solid, cohesive, and slippery to the touch. |
|
abrupt |

apex |
|
Having a distal boundary that is generally straight or plane and approximately perpendicular to the central axis. |
|
apiculum 1 pl. apicula |
