emargination |
= notch |
FEATURE |
|
A relatively small, acute sinus at the distal end of a laminar structure. |
obtriangular 2 |
= cuneate, wedge-shaped |
plane shape |
|
Inversely triangular; like the outline of the broad lateral face of a wedge, broadest at the apex. See also obdeltate. |
trullate |
= trowel-shaped, trulliform |
plane shape |
|
Broadest below the middle, more or less straightly attenuate to either end, the sides angled at the level of greatest width; like the blade of a mason's trowel. See also obtrullate, obtrulliform. |
heart-shaped 2 |
= cordate |
plane shape |
|
Fairly regularly attenuate from a broad, bilobate base to a narrow apex, the lobes large, rounded, retrorse, and intersecting; like the stylized outline of the broad lateral face of a heart. See also obcordate. |
root 2 |
= radix |
STRUCTURE |
|
A vascularized, primary or higher-order (branch) axis that is not differentiated into nodes and internodes and that branches endogenously, together with any non-axial structures borne from it; usually growing below ground level, but sometimes structurally and functionally specialized and growing wholly or partly aboveground (e.g. aerial root, knee root, pneumatophore). |
lanceolate |
= lancehead-shaped |
plane shape |
|
Elongate, moderately narrow, broadest just above the base and gradually attenuate toward the apex, the sides more or less straight; like the outline of the broad lateral face of a lance head. See also oblanceolate. |
stomium pl. stomia |
= stomatal pore |
FEATURE |
|
The opening in the wall of a sporangium, between the lip cells, through which the spores exit; in Psilotophyta, Lycopodiophyta, Equisetophyta, Polypodiophyta. |
globular |
= globose, orbicular, rotund, spheric(al), spheroid(al) |
solid shape |
|
Uniformly convex, circular in any median section and in outline when viewed from any angle; like a globe or sphere. |
impressed |
< sunken |
prominence |
|
Shallowly sunken. |
free-central |
|
placentation |
|
Upon the free axial column of a compound, unilocular ovary. |
areole 1 |
= areola |
STRUCTURE |
|
Any distinctive surficial discontinuity of generally circular outline, whether concave, flush, or convex; when protuberant, sometimes bearing trichomes or spines, as in some Cactaceae. This term is used only when such entities are deemed structurally distinctive enough to merit description in their own rights, rather than as aspects of the surface. |
coloration |
|
CHARACTER |
|
Hue(s), intensity(ies), and/or pattern (if any) of coloring. When more than one hue and/or intensity is involved, a term describing the pattern of contrast will be applicable, and the description as a whole should be phrased to indicate the particular role of each in the pattern; e.g., "ovaries striate, yellow on green"; "petals pink, spotted yellow basally"; "sepals green, suffused with red". |
manifestation |
|
CHARACTER |
|
Degree or nature of evidence when present within the context in point. |
vermiculate |
= worm-shaped |
solid shape |
|
Basically cylindric, elongate, and slender with bluntly rounded ends, variously curved over its length. |
bellied |
= ventricose |
solid shape |
|
Bulging unilaterally near the middle, as though with a belly. |
bifurcate |
< forked, furcate |
apex |
|
Having two terminal, antrorse branches or divisions arising from a common point or level, like the prongs of a fork. |
crumpled |
= corrugate |
aestivation |
|
Having members tightly and irregularly folded, the whole appearing as though wadded upon emergence. |
notch |
= emargination |
FEATURE |
|
A relatively small, acute sinus at the distal end of a laminar structure. |
corrugate 1 |
= crumpled |
aestivation |
|
Having members tightly and irregularly folded, the whole appearing as though wadded upon emergence. |
dodeca… |
= twelve-… |
prefix |
|
Indicating presence of or constitution by twelve entities of the type denoted by the term's stem; as in dodecandrous, dodecalocular, dodecastylous. |
reticulodromous |
|
venation |
|
Having a single median primary vein that branches to either side along the length of the lamina, the secondary veins running thence toward the margin, branching repeatedly, becoming less distinct, and yielding a dense higher-order reticulum near the margin. |
kneed |
= geniculate |
solid shape |
|
Elongate, abruptly bent, somewhat thicker at the angle, and appearing as though articulate like a leg at the knee. |
first glume |
|
STRUCTURE |
|
The lower (proximal) or sometimes solitary small bract inserted at the base of a grass (Poaceae) spikelet, the second glume, when present, inserted immediately above (distal to) it. |
floral cup 2 (strict sense) |
= hypanthium (strict sense) |
STRUCTURE |
|
A marginal protrusion from or enlargement of the receptacle (torus) of a flower, encircling and wholly, partly or not at all adnate to the gynoecium, bearing the perianth and androecium. |
locule |
= cell (not recommended), chamber (not recommended) |
FEATURE |
|
Any structurally distinct compartment within an anther, ovary, fruit, sporangium or other organ; not necessarily having any evolutionary integrity. |
