margin |
|
Having closely and irregularly spaced, irregularly shaped, often compound convexities that curve irregularly through three dimensions. |
acyclic |
= helical, spiral |
arrangement |
|
Disposed helically about and along the axis, each on a different radius than the one(s) vertically adjacent. |
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. |

coloration |
|
Having a pattern of more or less regularly disposed square zones of contrasting hues and/or intensities. |
helical 3 |

course |
|
Curving with constant or regularly increasing radius from one end to the other through three dimensions. |
placenta-shaped |
= placentiform |
solid shape |
|
Thickly discoid (disciform); like the generalized form of a human placenta. |
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. |
clinandrium pl. clinandria |
|
FEATURE |
|
The cavity in a floral column (gynostemium) within which the anthers are borne. |
arrowhead-shaped 2 |
= sagittate |
plane shape |
|
Generally triangular, tapering gradually from the base to an acute apex, the base with a relatively large, acute, retrorse lobe to either side; like the outline of the broad lateral face of an arrowhead. |
cell 1 |
|
STRUCTURE |
|
Any of the basic structural/functional units that collectively or individually make up the various tissues of a plant; comprising, at least while physiologically active, a nucleus with included genetic material (chromosomes), a surrounding cytoplasm with included organelles (e.g., ribosomes, mitochondria, plastids), an enclosing membrane, and an exterior cellulosic wall. |
epiphyllous |
|
position |
|
Upon the leaves, or partially adnate thereto and apparently arising therefrom. |
lip |
= labium; > labellum |
STRUCTURE |
|
Any substructure that resembles a lip, especially a portion of a perianth, calyx or corolla. |
taeniate |
= tapeworm-shaped |
solid shape |
|
Slender, elongate, basically cylindric or compressed-cylindric with shallow, narrow, more or less regular constrictions along its length, the whole apparently segmented and straight or variously curved. |
pseudoterminal |
|
position |
|
Only apparently terminal; originally subapical but displaced toward the apex by differential growth during development. |
bract 2 (strict sense) |
|
STRUCTURE |
|
Any primary or first-order lateral structure ontogenetically and anatomically analogous with, and therefore presumably homologous with, but relatively smaller than, a leaf, especially when subtending an inflorescence, other reproductive structure, or portion thereof; putatively, an evolutionarily reduced leaf. |
septum pl. septa |
> dissepiment, replum, trabecula |
STRUCTURE |
|
A topologically and/or texturally distinct wall or partition that separates chambers or locules within an ovary, fruit or sporangium. |
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. |
opposite 1 |
|
arrangement |
|
Disposed in pairs along the axis, the members of each pair inserted at the same level across from one another. |
flanged |
|
plane shape |
|
Having a relatively broad circumferential rim or ridge that protrudes laterally. |
stipule scar |
|
FEATURE |
|
A scar on a stem or petiole due to abscission of a stipule; having an outline like that of a transverse section through the base of the stipule inserted there; variously disposed, usually in pairs, adjacent to a point of leaf insertion, sometimes confluent with the leaf scar, sometimes confluent with stipule scars associated with an opposite leaf, the two sets of scars then more or less encircling the axis. |
furrow |
= colpus, fossula, groove, sulcus, vallecula |
FEATURE |
|
An elongate depression that is relatively shallow and narrow. |
latex pl. latices, latexes |
|
SUBSTANCE |
|
A moderately viscous and sticky exudate, often milky, sometimes otherwise colored or clear. Overlaps conceptually with gum. |
resinous 1 |
|
coating |
|
Of liquid or hardened resin. |
vasculature |
|
STRUCTURE |
|
The vascular strands of all orders (veins and veinlets) in a particular part or organ, regarded collectively; consisting of conducting tissues (xylem, phloem) and associated supporting and enclosing tissues (e.g., sclerenchyma, collenchyma). |
napiform |
= turnip-shaped |
solid shape |
|
Depressed-globose overall and strongly acuminate (concave-tapered) at the base; like the generalized form of a turnip. |
