STRUCTURE |

STRUCTURE |
|
Any pedestal-like prolongation of a floral receptacle extending beyond the distalmost level of perianth insertion and bearing the gynoecium. |
|
cupule |
|
STRUCTURE |
|
A cup-like structure inserted at the base of a fruit, partially enclosing it or not; composed of a persistent, usually dried, sometimes hardened involucre, perianth, or portion thereof, the constituent parts often coalescent, yielding a unitary structure. |
|
puberulent |
|
pubescence |
|
Finely pubescent in the restricted sense of that term. |
|
dull |
|
reflectance |
|
Reflecting only a low proportion of incident light, with no apparent sheen. |
|
rootstock |
= rhizome |
STRUCTURE |
|
An underground, usually horizontal stem, often superficially resembling a root but easily distinguished by the presence of nodes, from which it branches exogenously to produce the aboveground portion(s) of the shoot. |
|
serrate |
= sawtoothed |
margin |
|
Having regularly spaced, angular convexities oriented at an acute angle to the generalized perimeter. See also crenate (scalloped), crenulate (small-scalloped), dentate (toothed), denticulate (small-toothed), serrulate (small-sawtoothed). |
|
squamule 1 |
= squamella; < scale |
STRUCTURE |
|
A diminutive squama (lepis). |
|
hippocrepiform |
= horseshoe-shaped |
solid shape |
|
Relatively slender and strongly compressed, the whole strongly curved over its length in a plane perpendicular to the direction of compression and forming an incomplete circle, the ends somewhat straighter than the rest and parallel or nearly so; like a horseshoe. |
|
keel 2 |
= carina |
STRUCTURE |
|
Collectively, the two relatively small, connate or coherent, abaxial (lower) petals that form the keel-like portion of a papilionaceous corolla. |
|
vexillate |
|
aestivation |
|
Having a larger member oriented more or less perpendicular to and folded about the others. |
|
megaspore |
= macrospore (not recommended) |
STRUCTURE |
|
A female spore; a spore of the larger of two types produced by the sporophytes of a heterosporous taxon; produced in a megasporangium; giving rise upon germination to a megagametophyte. |
|
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). |
|
crested |
= cristate |
apex |
|
Having a laterally elongate, relatively thin, irregular or notched protrusion. |
