trichome |
Unicellular to multicellular with transverse partitions (septa) that are common cell walls (intercellular) and/or intrusions from longitudinal cell walls (intracellular). |
|
septicidal |
|
dehiscence |

Splitting longitudinally into or through the suture(s) in the outer wall and, if present, through the septum(-a) between locules, the latter thus opened indirectly to the outside. |
|
septifragal |
|
dehiscence |
fruit |
Splitting through the exterior wall suture(s) but not the septum(-a), the valves of the wall then separating from the septum(-a) and the locules thus opened directly to the outside. |
|
septum pl. septa |

|
A topologically and/or texturally distinct wall or partition that separates chambers or locules within an ovary, fruit or sporangium. |

pubescence |
|
Of or bearing long, fine, appressed, capillate trichomes and like silk to the touch. |
|
series |
= cycle, verticil, whorl |
STRUCTURE |
|
A set of three or more lateral structures that are inserted around an axis at the same level. |
|
serotinous |
= late-maturing |
maturation |
structure |
Maturing late in the growing season, or late relative to the developmental progress of its context. |
|
serrate |
= sawtoothed |
margin |
|
Having regularly spaced, angular convexities oriented at an acute angle to the generalized perimeter. See also crenate (scalloped), crenulate (small-scalloped), dentate (toothed), denticulate (small-toothed), serrulate (small-sawtoothed). |
|
serrulate |
= small-sawtoothed |
margin |
|
Finely serrate (sawtoothed). See also crentate (scalloped), crenulate (small-scalloped), dentate (toothed), denticulate (small-toothed). |
|
sessile |
= exstipitate, stalkless, unstalked |
architecture |
structure |
Lacking a stalk, thus inserted ("sitting") directly upon the bearing structure. |
|
seta 1 pl. setae |
= arista, awn, bristle |
STRUCTURE |
|
A slender, more or less straight and stiff, fine-pointed, terminal or subterminal appendage or prolongation, sometimes a continuation of the bearing structure's central primary vein, as on a glume, lemma, or palea in Poaceae (Gramineae). |
|
seta 2 pl. setae |
= bristle; > glochid, glochidium |
STRUCTURE |
|
A trichome that is elongate, slender, more or less straight, terete, fine-pointed, and stiff. |
|
setaceous |
= bristle-shaped, setiform |
solid shape |
|
Elongate, slender, terete, straight, terminating in a fine point, and apparently stiff; like a bristle. |
|
setiform |
= bristle-shaped, setaceous |
solid shape |
|
Elongate, slender, terete, straight, terminating in a fine point, and apparently stiff; like a bristle. |
|
setose |
= hispid; < bristly |
pubescence |
|
Bearing relatively long and slender, more or less straight, terete, fine-pointed, stiff trichomes. See also setulose (hispidulous, small-bristly). |
|
setulose |
= hispidulous, small-bristly |
pubescence |
|
Finely setose (hispid). |
|
seven-… |
= hepta… |
prefix |
|
Indicating presence of or constitution by seven entities of the type denoted by the term's stem; as in seven-leafleted, seven-loculed, seven-winged. |
|
shaggy |
= villose, villous |
pubescence |
|
Bearing sparse, long, slender, soft, capillate trichomes that are not intertwined. See also villosulous. |
|
sharp |
= acute |
apex |
|
Acutely angular; regularly and more or less straightly attenuate to an angular tip, the sides intersecting at an angle of less than 90°. |
|
sheath (leaf) |
|
STRUCTURE |
|
The lower (basal or proximal), fundamentally laminar but strongly involute portion of one of the non-petiolate leaves characteristic of most monocotyledons (Liliidae); distinct from the leaf blade, which, when present, is borne distally upon it; analogous, though not necessarily homologous, with a petiole; usually more or less completely enclosing a portion of the stem above the node from which the leaf is borne. |
|
sheathed |
= vaginate |
architecture |
structure |
Closely enclosed over some or all of its length by a terete or involute structure. |
|
sheathing 1 |
|
architecture |
foliaceous structure |
Differentiated into distinct proximal and distal portions, the former terete or involute and closely enclosing the bearing axis above the point of insertion. |
|
sheathing 2 |
|
base |
laminar structure |
Terete or involute and closely enclosing the supporting axis for some distance above the point of insertion. |
