| Term | Synonyms | Category | Limitation | Definition |
|---|---|---|---|---|
| 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 | = arrowhead-shaped | 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. | |
| sap | SUBSTANCE | Generally, the fluid content of a plant body; more precisely, the sugary fluid transported by the phloem. | ||
| saprophytic | nutrition | plant | Heterotrophic and obtaining essential nourishment directly from the decomposing remains of other organisms. | |
| sapwood | STRUCTURE | That portion of the wood (xylem) of a stem or root whose cells are still living and functional; concentric about the heartwood once the latter has begun to form. | ||
| sarcocaulous | = fleshy-stemmed | texture | plant | Having main stems that are sarcous (carnose, fleshy). |
| sarcous | = carnose, fleshy | texture | Fairly firm and dense, juicy or at least moist, and easily cut. | |
| sarmentose | = runnering, stoloniferous | architecture | plant | Producing stolons (runners), by means of which it propagates vegetatively. |
| sausage-shaped | = botuliform | solid shape | Arcuately cylindric with rounded ends. | |
| sawtooth | STRUCTURE | One of a series of regularly spaced, angular, marginal convexities oriented at an acute angle to the generalized perimeter of a laminar structure. See also sawtoothlet, scallop (crena), scalloplet (crenule), tooth, toothlet. | ||
| …-sawtoothed | = …serrate | margin | Having the number of orders of sawteeth indicated by the prefix, one upon another; as in twice-sawtoothed. See also …-scalloped (…crenate), …-toothed (…dentate). | |
| sawtoothed | = serrate | margin | Having regularly spaced, angular convexities oriented at an acute angle to the generalized perimeter. See also scalloped (crenate), small-scalloped (crenulate), small-sawtoothed (serrulate), small-toothed (denticulate), toothed (dentate). | |
| sawtoothlet | STRUCTURE | A diminutive sawtooth. See also scallop (crena), scalloplet (crenule), tooth (dens), toothlet. | ||
| scabrate | = rough, scabrid, scabridous, scabrous | relief | Having small, stout, stiff, more or less acute protrusions. | |
| scabrellate | = scabrellous, scabridulous | relief | Minutely scabrous (rough, scabrate, scabrid, scabridous). See also spiculate, which is not clearly distinct in its application. | |
| scabrellous | = scabrellate, scabridulous | relief | Minutely scabrous (rough, scabrate, scabrid, scabridous). See also spiculate, which is not clearly distinct in its application. | |
| scabrid | = rough, scabrate, scabridous, scabrous | relief | Having small, stout, stiff, more or less acute protrusions. | |
| scabridous | = rough, scabrate, scabrid, scabrous | relief | Having small, stout, stiff, more or less acute protrusions. | |
| scabridulous | = scabrellate, scabrellous | relief | Minutely scabrous (rough, scabrate, scabrid, scabridous). See also spiculate, which is not clearly distinct in its application. | |
| scabrous 1 | = rough | pubescence | Of or bearing coarse, stiff, ascending trichomes and markedly rough to the touch. |
