| Term | Synonyms | Category | Limitation | Definition |
|---|---|---|---|---|
| strict | course | Lacking any curve or bend. | ||
| strigillose | = strigulose | pubescence | Finely strigose. | |
| strigose | pubescence | Bearing sharp, rigid, appressed, capillate trichomes. See also strigillose (strigulose). | ||
| strigulose | = strigillose | pubescence | Finely strigose. | |
| striped | coloration | Having one or more elongate, relatively narrow and, when multiple, more or less parallel, areas of contrasting hue and/or intensity. | ||
| strobiloid | architecture | flower | Characterized by a general lack of adnation among the different sets of basic floral structures, any significant degree of fusion limited to connation within sets, thus with ovary(ies) superior and lacking a floral tube. | |
| strobilus pl. strobili | = cone; > female cone, macrostrobilus (not recommended), male cone, megastrobilus, microstrobilus | STRUCTURE | A compound or complex reproductive structure consisting of a central axis bearing congested sporophylls and sometimes other lateral members (e.g., bracts) that are sterile. | |
| strombuliform | = spire-shaped | solid shape | Attenuate-spiral in three dimensions, the coils contiguous or not. | |
| strophiole | = caruncle | STRUCTURE | An outgrowth from the seed coat (testa) around or near the hilum and micropyle, or from the raphe. | |
| style | STRUCTURE | A narrow, usually elongate, ontogenetically distal portion of a simple or compound pistil, overtopping the ovary and bearing one or more stigmas; arising from the summit of the ovary, but sometimes apparently from its base at maturity to ontogenetic displacement from its primordial distal position. In a compound pistil the various simple (carpellary) components of the style(s) may not be connate over their entire lengths; the pistil is then regarded as having a branched style or styles. | ||
| …styled | = …stylous | architecture | flower, pistil | Having the number of styles indicated by the prefix; as in five-styled. |
| stylopodium pl. stylopodia | STRUCTURE | A discoid enlargement at the base of the styles; esp. in Apiaceae (Umbelliferae). | ||
| …stylous | = …styled | architecture | flower, pistil | Having the number of styles indicated by the prefix; as in monostylous, pentastylous, polystylous. |
| subapical | = subterminal | insertion | Lateral and just below the apex. | |
| subapical | = subterminal | position | Lateral and just below the apex. | |
| sub-basifixed | fixation | Attached just above its base. | ||
| subcircular | = subround; suborbicular misapplied, subrotund misapplied | plane shape | Compressed circular or very broadly elliptic, only slightly longer than wide. | |
| subequal | size | equivalent structures | Nearly uniform in extent. See also equal, unequal. | |
| suberous | = corky | texture | Firm, relatively light, discontinuous but strongly cohesive, and resilient. | |
| subglobose | = suborbicular, subrotund, subspheric(al), subspheroid(al) | solid shape | Broadly ellipsoid with a length:width ratio closely approaching 1:1; almost globose, slightly longer than broad. | |
| subinferior | = half-inferior | position | ovary | Having its proximal portion enclosed by a floral tube casing, the more distal portions of the perianth and/or androecium thus arising between its base and apex. |
| submerged | = submersed | location | plant, structure of aquatic plant | Beneath the water surface. |
| submergent | location | structure of aquatic plant | Descending from above the water surface to a point beneath it. | |
| submersed | = submerged | location | plant, structure of aquatic plant | Beneath the water surface. |
| subopposite | arrangement | Alternate but verging on opposite. |
