columella 1 pl. columellae, columellas |
= carpophore; < stalk |
STRUCTURE |
|
Any pedestal-like prolongation of a floral receptacle extending beyond the distalmost level of perianth insertion and bearing the gynoecium. |
helical 1 |
= acyclic, spiral |
arrangement |
|
Disposed helically about and along the axis, each on a different radius than the one(s) vertically adjacent. |
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. |
leaf 2 pl. leaves |
= microphyll |
STRUCTURE |
|
A small, lateral, leaf-like enation that, evolutionarily, is not a true leaf, i.e., whose vasculature, if any, consists of only a single median strand not ontogenetically integral with the vasculature of the bearing stem and not associated with leaf gaps in the stele of the stem; in Psilotophyta, Lycopodiophyta, Equisetophyta. |
tooth pl. teeth |
= dens |
STRUCTURE |
|
One of a series of regularly spaced, angular, marginal convexities oriented more or less perpendicular to the generalized perimeter of a laminar structure. See also sawtooth, sawtoothlet, scallop (crena), scalloplet (crenule), toothlet. |
ensate |
= sword-shaped |
plane shape |
|
Elongate and moderately slender, broadest at the base and gradually attenuate to a short, more strongly attenuate, acute apex; like the outline of the lateral face of a broadsword blade. |
fiddle-shaped |
= pandurate |
plane shape |
|
Basically obovate but with deep, rounded sinuses opposite one another in the proximal half; like the frontal outline of an inverted fiddle body. |
scaly 1 |
> lepidote, squamate, squamellose, squamose |
pubescence |
|
Bearing scales [squamae (lepides) or squamellae]. |
…crenate |
= …-scalloped |
margin |
|
Having the number of orders of crenae (scallops) indicated by the prefix, one upon another; as in bicrenate, twice-crenate. See also …dentate (…-toothed), …serrate (…-sawtoothed). |
incurved |
|
orientation |
|
Curving adaxially. See also decurved. |
subtending |
|
position |
|
Arising from the axis just below and very near to the base of some other specified lateral structure. This term is meaningless if the structure that is subtended is not indicated. |
mamillate |
|
relief |
|
Bearing mamillae. |
unctuous 2 |
= greasy, oily, oleaginous |
texture |
|
Liquid or deformably solid, cohesive, and slippery to the touch. |
articulation |
= joint |
STRUCTURE |
|
A distinct, relatively narrow zone of demarcation between adjacent main portions of an elongate structure, often thicker than the rest of the structure and sometimes a site of eventual abscission. |
sickle-shaped 1 |
= falcate |
plane shape |
|
Elongate and laterally arcuate with the lateral edges more or less concentric, the degree of curvature decreasing distally or not; like the outline of the face of a sickle blade. |
cleft |
? dissected, divided, lobate, lobed, parted, partite, segmented |
solid shape |
|
Having two or more component sectors or peripheral protrusions that are delimited by concavities in the margin or surface 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). |
apiculum 1 pl. apicula |
|
STRUCTURE |
|
A short, slender, angular tip that is not notably harder or stiffer than the main body of the bearing structure. See also mucro. |
lacunate |
|
relief |
|
Having relatively large and deep depressions overall. |
tessellate 1 |
= checkered |
coloration |
|
Having a pattern of more or less regularly disposed square zones of contrasting hues and/or intensities. |
eccentric |
|
position |
|
Having a center or axis of symmetry not coincident with that of the context of reference. |
faceted |
|
solid shape |
|
Having numerous, relatively small, flat or shallowly curved portions of the external surface that are bounded by more or less distinct angular discontinuities in that surface. |
saddle-shaped |
= selliform |
solid shape |
|
Relatively thin, broad and long, strongly compound-curved, concavely from end to end and convexly from side to side; like the generalized shape of a saddle. |
bisexual |
= hermaphroditic |
reproduction |
|
Having functional reproductive structures of both sexes. See also perfect. |
halberd-head-shaped 2 |
= hastate |
plane shape |
|
Basically triangular with an acute apex and two large, widely divergent basal lobes, each generally triangular and distally acute; like the stylized outline of the broad lateral face of a halberd head. |
corniform |
= horn-shaped |
solid shape |
|
Straight or curved and slenderly conic or conoidal, like an animal horn. |
