venation |
|
Having a single median primary vein that branches to either side along the length of the lamina, each secondary vein running thence toward and bifurcate near the margin, one branch terminating at the margin, the other upwardly arcuate and merging with the superadjacent secondary vein, thus forming one of a series of marginal loops. |

arrangement |
bundle scars |
Forming an incomplete ellipsis, like the letter U. |

architecture |
flower, perianth, calyx |
Having the number of sepals indicated by the prefix; as in four-sepaled. |
|
sepal-like |
= sepaloid |
architecture |
structure |
Resembling a sepal in shape, texture and color. |

…sepalous |
= …sepaled |
architecture |
flower, perianth, calyx |
Having the number of sepals indicated by the prefix; as in tetrasepalous. |
|
septal |
|
insertion |
|
Upon or otherwise directly associated with the septum or septa. |
|
septal |
|
position |
|
Upon or otherwise directly associated with the septum or septa. |
|
septate 1 |
> trabeculate |
architecture |
|
Having one or more septa. |
|
septate 2 |
|
architecture |
trichome |
Unicellular to multicellular with transverse partitions (septa) that are common cell walls (intercellular) and/or intrusions from longitudinal cell walls (intracellular). |
|
septicidal |
|
dehiscence |
fruit |
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 |
> dissepiment, replum, trabecula |
STRUCTURE |
|
A topologically and/or texturally distinct wall or partition that separates chambers or locules within an ovary, fruit or sporangium. |
|
seriate |
= cyclic, verticillate, whorled |
arrangement |
|
Disposed along the axis in groups of three or more, the members of each group (cycle, series, verticil, whorl) inserted around the axis at the same level. |
|
…seriate 1 |
|
architecture |
trichome |
Multicellular with the number of longitudinal columns of superposed cells indicated by the prefix; as in biseriate, multiseriate, uniseriate. |
|
…seriate 2 |
= …cyclic, …verticillate, …whorled |
arrangement |
|
Disposed in the number of series (cycles, verticils, whorls) indicated by the prefix; as in biseriate, 3-seriate. |
|
sericeous |
= silky |
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. |
