sterigma pl. sterigmata |
|
STRUCTURE |
|
A portion of a lamina that is prolonged and adherent to the supporting axis beneath the point of vascular insertion. |
awn |
= arista, bristle, seta |
STRUCTURE |
|
A slender, more or less straight and stiff, fine-pointed, terminal or subterminal appendage or prolongation, sometimes a continuation of the bearing structure's central primary vein, as on a glume, lemma, or palea in Poaceae (Gramineae). |
pseudoterminal |
|
insertion |
|
Only apparently terminal; originally subapical but displaced toward the apex by differential growth during development. |
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. |
bracteolate |
= bractleted |
architecture |
|
Bearing or subtended by one or more bracteoles (bractlets, prophylls). |
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. |
scutelliform |
= platter-shaped, scutellate |
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. |
inframedial |
|
position |
|
Slightly below the middle of the structure in point. |
superficial |
= surficial |
insertion |
|
Directly upon the surface of the structure in point. |
enlarged |
|
size |
|
Unusually or unexpectedly large. |
resinous 1 |
|
coating |
|
Of liquid or hardened resin. |
carpophore 2 |
= columella; < stalk |
STRUCTURE |
|
Any pedestal-like prolongation of a floral receptacle extending beyond the distalmost level of perianth insertion and bearing the gynoecium. |
size |
|
CHARACTER |
|
Nature as to absolute or comparative extent in any one dimension or in area or volume. |
haustorium pl. haustoria |
|
STRUCTURE |
|
An absorbing and anchoring organ, often root-like, excrescent from a vegetative part of a parasitic or hemiparasitic plant, by which the plant communicates intimately with and derives sustenance and support from its host plant, into whose tissues the haustorium intrudes. |
crena pl. crenae |
= scallop |
FEATURE |
|
A rounded, marginal convexity or concavity in a series of such that alternate regularly and are oriented more or less perpendicular to the generalized perimeter of a laminar structure. See also crenule (scalloplet), dens (tooth), sawtooth, sawtoothlet, toothlet. |
piliferous |
|
apex |
|
Having a distinct, fine, weak, hair-like portion or protrusion. |
arrangement |
|
CHARACTER |
|
Disposition of equivalent structures with respect to one another (positions/insertions and/or orientations, regarded collectively) within some explicit or implicit standard context. Overlaps conceptually with habit, insertion, orientation, position, and shape. |
lanuginose |
< cottony |
pubescence |
|
Bearing relatively long and fine, intertwined, somewhat matted, capillate trichomes. |
biconvex 2 |
= lens-shaped, lenticular |
solid shape |
|
Relatively thin with two round, convex, opposite broad faces intersecting acutely at the circumferential edge; like a double-convex lens. See also disciform (discoid), meniscoid. |
throat 1 |
|
STRUCTURE |
|
The far distal portion of a perianth, calyx, or corolla tube, or of a leaf sheath, surrounding the orifice of the tube or sheath, sometimes constricted relative to the diameter of the main body of the tube or sheath; except in disc florets of Asteraceae (Compositae). |
female cone |
= macrostrobilus (not recommended), megastrobilus |
STRUCTURE |
|
A cone (strobilus) whose fertile organs are all megasporophylls. |
scabridous |
= rough, scabrate, scabrid, scabrous |
relief |
|
Having small, stout, stiff, more or less acute protrusions. |
