shoot 1 |
|
STRUCTURE |
|
Collectively, all those portions of a plant body that are anatomically distinct from the root, the component axes differentiated into nodes and internodes, and branching exogenously from the former. |
shoot 2 |
|
STRUCTURE |
|
A vascularized axis that is differentiated into nodes and internodes and that branches exogenously from the former, together with any non-axial structures borne from it. |
short-shoot |
= spur |
STRUCTURE |
|
A first- or higher-order woody stem branch having relatively unelongated internodes, thus proximate nodes, and limited duration of growth, usually branching little if at all; often a main locus of flower production; usually more or less perpendicular to the axis that bears it and resembling a spur projecting from it; sometimes becoming more or less spinose after elongation ceases; esp. in Rosaceae. |
showy |
< conspicuous |
manifestation |
|
Prominently evident and attractive due to size, shape and/or coloration. |
shrub |
= frutex; > bush |
nominative |
plant |
Perennial, woody, relatively short, with a single main stem that is not distinctly columnar and branches from or above ground level, the branches often crowded. See also subshrub (suffrutex, undershrub), tree, woody clump. |
shrubby |
> bushy, frutescent, fruticose |
habit |
plant |
Having or developing the character of a shrub. See also arboreous, arborescent, subshrubby, suffrutescent, suffruticose, tree-like, woody-clumping. |
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. |
sickle-shaped 2 |
= falcate |
solid shape |
|
Elongate, strongly compressed, and arcuate in the plane of compression, the two faces more or less plane and parallel, the degree of curvature decreasing distally or not; like a sickle blade. |
sigmoid 1 |
= S-shaped |
course |
|
Curved more or less regularly first in one direction and then in the opposite direction, like the letter S. |
sigmoid 2 |
= S-shaped |
solid shape |
|
Elongate with more or less constant width or diameter and curved more or less regularly first in one direction and then in the opposite direction, like the letter S. |
siliceous |
|
texture |
epidermis, trichome |
Containing deposits of silica, thus hardened and abrasive. |
silicle |
|
nominative |
fruit |
Like a silique, but only slightly longer than broad to broader than long; esp. in Brassicaceae (Cruciferae), Capparaceae. |
silique |
|
nominative |
fruit |
Dry, septifragal, two-loculed and derived from a single, superior, compound ovary; much longer than broad; dehiscing along two sutures, one adaxial, one abaxial, leaving a single persistent septum (replum) after the two valves of the pericarp have fallen away; esp. in Brassicaceae (Cruciferae), Capparaceae. See also silicle. |
silky |
= sericeous |
pubescence |
|
Of or bearing long, fine, appressed, capillate trichomes and like silk to the touch. |
simple 1 |
|
architecture |
|
Externally unitary and comprising only one basic morphological unit; not compound in either sense of that term. |
simple 2 |
|
architecture |
trichome |
Unicellular and unbranched. |
simple-craspedodromous |
|
venation |
|
Having a midvein that branches to either side along the length of the lamina, the secondary veins and their branches all running toward and terminating at the margin. |
simple-lipped |
= haplocheilic |
architecture |
stomate |
Having subsidiary cells not derived from the primary stoma mother cell and thus not immediately related ontogenetically to the guard cells. |
single-leafleted |
= one-leafleted, unifoliolate |
architecture |
foliaceous structure |
Structurally compound but with only one leaflet, whose nature (as a leaflet, not a leaf) is revealed by an evident articulation with the petiole, this condition presumably derived by evolutionary reduction from a multifoliolate precursor. |
single-veined |
= hyphodromous, one-veined |
venation |
|
Having one median, primary vein and no other venation externally evident. |
single-… |
= mono…, one-…, uni… |
prefix |
|
Indicating presence of or constitution by one entity of the type denoted by the term's stem; as in single-celled, single-headed, single-seeded. See also entries for particular terms with this prefix whose meanings, at least in some applications, are more specific than usually indicated by such combination. |
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). |
sinuate |
|
margin |
|
Having regular, curved, smoothly connected, alternating concavities and convexities. See also repand. |
