Basically obovate with a series of retrorse, acute lobes on either side, these diminishing in size toward the base. |
runner |
= stolon |
STRUCTURE |
|
A slender stem that grows horizontally upon or just beneath the ground surface, rooting at the nodes and giving rise to erect shoot segments at some nodes and/or at its apex. |
runnering |
= sarmentose, stoloniferous |
architecture |
plant |
Producing runners (stolons), by means of which it propagates vegetatively. |
S-shaped 1 |
= sigmoid |
course |
|
Curved more or less regularly first in one direction and then in the opposite direction, like the letter S. |
S-shaped 2 |
= sigmoid |
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. |
saccate 1 |
= alate, vesiculate, winged |
architecture |
pollen grain |
Having lateral lobes or enations resembling sacs or somewhat inflated wings. |
saccate 2 |
= bag-shaped, pouch-shaped, sack-shaped |
solid shape |

sack-shaped |
= bag-shaped, pouch-shaped, saccate |
solid shape |
|

saddle-shaped |
= selliform |
solid shape |
|
Relatively thin, broad and long, strongly compound-curved, concavely from end to end and convexly from side to side; like the generalized shape of a saddle. |
sagittate 1 |

base |
laminar structure |
Having two retrorse, generally triangular lobes, one to either side. |
sagittate 2 |
= arrowhead-shaped |
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. |
salient |
= patent, porrect, spreading |
orientation |
lateral structure |
Antrorse and diverging at an acute angle from the bearing structure. |
salt-excreting |
|
exudation |
|
Accumulating salt and discharging it directly to the exterior in a concentrated aqueous solution, the salt then crystallizing on the exterior following evaporation of the fluid medium; when salt-excreting glands are indicated in the nominative, usually they are called simply salt glands. |
salverform |
= hypocrateriform |
solid shape |
perianth, calyx, corolla |
Having a relatively long, slender tube and a divaricate, planate limb resembling a round platter. |
samara |
|
nominative |
fruit |
Dry, indehiscent and having one or more integral alate portions that aid in aerial dispersal. |
