sorus pl. sori |
|
STRUCTURE |
|
A cluster of sporangia borne upon a fertile frond, usually on its abaxial surface; often covered during maturation by a protective membrane, the indusium, that is an outgrowth from the epidermis; in Polypodiophyta. |
solitary 2 |
|
habit |
plants |
Growing singly; not aggregated. |
solitary 1 |
|
arrangement |
|
Disposed singly, each remote from any others. |
solid shape |
|
CHARACTER |
|
Overall three-dimensional form or aspect(s) thereof. Overlaps conceptually with architecture, arrangement, habit, insertion, orientation, position, relief, and texture (as to thickness). |
solid |
= continuous |
architecture |
pith |
Uninterrupted by cavities and essentially homogeneous in texture at axis maturity. |
soft |
|
texture |
|
Yielding under slight pressure. |
soboliferous |
|
architecture |
plant |
Having several, loosely clumped, principal stems that arise from a common underground stem system, each distinct above ground level. |
snail-shell-shaped |
= cochleate |
solid shape |
|
Relatively broad and short, basically round in transverse section, resembling a rapidly tapering spire overall, the exterior helically convoluted. |
smooth 2 |
|
relief |
bark |
Unfissured; not cracked or split to any significant degree. |
smooth 1 |
|
relief |
|
Even or unrelieved overall. Strictly applied, this term refers only to the surface proper; however, it is often used to mean glabrous as well. |
small-toothed |
= denticulate |
margin |
|
Finely toothed (dentate). See also sawtoothed (serrate), scalloped (crenate), small-scalloped (crenulate), small-sawtoothed (serrulate). |
small-scalloped |
= crenulate |
margin |
|
Finely scalloped (crenate). See also sawtoothed (serrate), small-sawtoothed (serrulate), small-toothed (denticulate), toothed (dentate). |
small-sawtoothed |
= serrulate |
margin |
|
Finely sawtoothed (serrate). See also scalloped (crenate), small-scalloped (crenulate), small-toothed (denticulate), toothed (dentate). |
small-dotted |
= puncticulate |
coloration |
|
Finely dotted (punctate). |
small-dotted |
= puncticulate |
relief |
|
Finely dotted (punctate). |
small-bristly |
= setulose |
pubescence |
|
Finely setose (hispid). |
small-beaked |
= rostellate |
apex |
|
Diminutively beaked (rostrate). |
slipper-shaped |
= calceolate |
solid shape |
|
Relatively thin-walled with an essentially hollow interior that is open on one side at the broader end. |
slashed |
= laciniate; < cut, incised, lacerate, torn |
plane shape |
|
Having relatively close, more or less straight lines of separation exending inward from the margin. See also cleft (dissected, divided, lobate, lobed, parted, partite, segmented). |
size |
|
CHARACTER |
|
Nature as to absolute or comparative extent in any one dimension or in area or volume. |
six-… |
= hexa… |
prefix |
|
Indicating presence of or constitution by six entities of the type denoted by the term's stem; as in six-angled, six-sepaled, six-styled. |
sinus pl. sinus, sinuses |
|
FEATURE |
|
The space, indentation, or invagination (or, for some descriptive purposes, the outline thereof) between and delimiting any two consecutive or adjacent lobes or teeth of a structure. |
sinuous |
|
course |
|
Regularly wavy in one plane, curved alternately and more or less regularly to either side. |
sinuate |
|
margin |
|
Having regular, curved, smoothly connected, alternating concavities and convexities. See also repand. |
sinistrorse |
= leftward |
orientation |
|
Directed to the left, relative to the direction of growth along an explicit or implicit axis of reference. See also dextrorse (rightward). |
