ring-porous |
|
porosity |
|
Heterogeneously porous, with macroscopically distinct concentric seasonal growth increments (rings), each with numerous large vessels toward the inside and fewer and smaller ones toward the outside. |
absent |
|
presence |
|
Not occurring within the context in point. |
cut |
= incised, lacerate, torn; > laciniate, slashed |
plane shape |
|
Having straight to irregular lines of separation extending inward from the margin. See also cleft (dissected, divided, lobate, lobed, parted, partite, segmented). |
barbella pl. barbellae |
= barbel |
STRUCTURE |
|
A small barb. |
pseudoterminal |
|
position |
|
Only apparently terminal; originally subapical but displaced toward the apex by differential growth during development. |
cereous 1 |
= ceraceous, waxen, waxy; > caesious, glaucescent, glaucous, pruinose |
coating |
|
Covered with wax or a wax-like substance. |
lentiginous |
= dusty, lentiginose |
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. |
trapeziform |
|
plane shape |
|
Four-sided and either asymmetrical or bilaterally symmetrical like a triangle truncated distally perpendicular to its central axis. |
mealy 1 |
= farinaceous; < crumbling, fatiscent |
texture |
|
Of or bearing minute, relatively stout trichomes that are collectively meal- or flour-like and easily detached. |
flabelliform |
= fan-shaped, flabellate |
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. |
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. |
dissepiment |
< septum; > replum |
STRUCTURE |
|
A wall or partition between adjacent locules of an ovary or fruit. |
angular |
|
plane shape |
|
Having sides that meet at acute or obtuse angles. |
inframedial |
|
position |
|
Slightly below the middle of the structure in point. |
superficial |
= surficial |
insertion |
|
Directly upon the surface of the structure in point. |
bulblet |
= bulbil |
STRUCTURE |
|
A small bulb-like structure produced from a sterile or fertile plant structure other than a bulb, usually within a leaf axil, leaf sinus, or inflorescence, serving as a vegetative propagule. |
enlarged |
|
size |
|
Unusually or unexpectedly large. |
resinous 1 |
|
coating |
|
Of liquid or hardened resin. |
compound |
= composite |
architecture |
|
Unitary as a whole but comprising two or more equivalent substructural entities, these topologically distinct (e.g., leaflets in a compound leaf) or not (e.g., carpels in a compound pistil). |
cristate |
= crested |
apex |
|
Having a laterally elongate, relatively thin, irregular or notched protrusion. |
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. |
piliferous |
|
apex |
|
Having a distinct, fine, weak, hair-like portion or protrusion. |
attenuate 1 |
= concave-tapered |
base |
|
Gradually diminishing in width or diameter toward the proximal end, the sides longitudinally concave. Corresponds with acuminate for apex shape. |
lanuginose |
< cottony |
pubescence |
|
Bearing relatively long and fine, intertwined, somewhat matted, capillate trichomes. |
