episepalous |
|
position |
|
Upon the sepals, or partially adnate thereto and apparently arising therefrom. |
rightward |
= dextrorse |
orientation |
|
Directed to the right, relative to the direction of growth along an explicit or implicit axis of reference. See also leftward (sinistrorse). |
cushion-shaped |
= mound-shaped, pulvinate, pulviniform |
solid shape |
|
Essentially round in transverse section, much broader than long or high, with a convex distal face that intersects either a more or less plane proximal face or, when the structure is sessile, its bearing surface. |
obdeltate |
|
plane shape |
|
Approximately equilaterally triangular, broadest distally, and regularly attenuate to an angular base; inversely deltate; equilaterally cuneate. |
abrupt |
= truncate |
apex |
|
Having a distal boundary that is generally straight or plane and approximately perpendicular to the central axis. |
cuspidate |
|
apex |
|
Tapering gradually to a rigid tip composed of both vascular and laminar tissues. |
obdeltoid |
< three-angled, trigonous, triquetrous |
solid shape |
|
Three-angled (trigonous, triquetrous), broadest distally, and regularly attenuate to an angular base; inversely deltoid. |
sterigma pl. sterigmata |
|
STRUCTURE |
|
A portion of a lamina that is prolonged and adherent to the supporting axis beneath the point of vascular insertion. |
barbel |
= barbella |
STRUCTURE |
|
A small barb. |
pseudoterminal |
|
insertion |
|
Only apparently terminal; originally subapical but displaced toward the apex by differential growth during development. |
ceraceous 2 |
cereous, waxen, waxy |
texture |
|
Having the consistency of wax. |
lentiginose |
= dusty, lentiginous |
coating |
|
Covered with a more or less even deposit of minute, dry, macroscopically indistinguishable particles. See also pulverulent (granuliferous, powdery), which is not clearly distinct in its application. |
transverse 2 |
|
orientation |
|
Perpendicular to the long axis of the context of reference. |
maturation |
|
CHARACTER |
|
Timing of the attainment of functional maturity, sometimes relative to other structures, sometimes as to constituent structures relative to each other. |
flabellate |
= fan-shaped, flabelliform |
solid shape |
|
Strongly compressed, broadest near the apex and attenuate to a narrow base, plaited longitudinally, the alternating folds radiating from the base, the whole basically triangular in broad aspect; like a partially expanded folding fan. |
scutellate |
= platter-shaped, scutelliform |
solid shape |
|
Relatively thin with opposite broad oval faces, shallowly concave-convex; like a serving platter. See also scutate (buckler-shaped, scutiform), which is not clearly distinct in its application. |
dissected |
? cleft, divided, lobate, lobed, parted, 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 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). |
…angled |
= …gonous |
solid shape |
|
Elongate with the number of longitudinal angles indicated by the prefix, the intervening sides transversely flat or curved; as in four-angled. See also …angular (…gonal), deltoid, obdeltoid, triquetrous. |
inframedial |
|
insertion |
|
Slightly below the middle of the structure in point. |
superaxillary |
|
position |
|
Internodal but close to and directly above the axil(s). |
