connivent |
|
arrangement |
|
Converging and distally contiguous; esp. arcuate stamens with anthers contiguous. |
|
paired |
= conjugate, geminate |
arrangement |
|
Inserted by pairs, the members of each fused or not. |
|
radiant 2 |
= radial, radiate, stellate |
arrangement |
|
Disposed about and mutually divergent from a common geometric center in two or three dimensions, thus collectively actinomorphic. |
|
rosetted |
= rosulate |
arrangement |
leaves |
Forming a rosette; strongly congested and disposed in radial symmetry about the main stem at or very near its base, seeming to arise at the same level and often overlapping laterally; esp. in perennial herbs. |
|
decussate |
|
arrangement |
|
Opposite with successive pairs radially oriented at right angles to one another, thus polystichous with four equidistant ranks. |
|
helical 1 |
= acyclic, spiral |
arrangement |
|
Disposed helically about and along the axis, each on a different radius than the one(s) vertically adjacent. |
|
ladder-like |
= scalariform |
arrangement |
|
Disposed in vertical sequence with long axes horizontal and parallel. |
|
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. |
|
radiate 2 |
= radial, radiant, stellate |
arrangement |
|
Disposed about and mutually divergent from a common geometric center in two or three dimensions, thus collectively actinomorphic. |
|
pleurorhizal |
= accumbent |
arrangement |
cotyledons |
Having the two cotyledons facing and parallel (adaxial surfaces contiguous) and recurved together, one lateral edge of each abutting the hypocotyl and radicle. |
|
contiguous |
|
arrangement |
|
Touching one another. |
|
valvate 2 |
|
arrangement |
planate structures |
Not overlapping, adjacent members laterally contiguous at their margins. |
|
…seriate 2 |
= …cyclic, …verticillate, …whorled |
arrangement |
|
Disposed in the number of series (cycles, verticils, whorls) indicated by the prefix; as in biseriate, 3-seriate. |
|
…angular 1 |
|
arrangement |
bundle scars |
Forming a figure with the number of sides indicated by the prefix. |
|
whorled |
= cyclic, seriate, verticillate |
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. |
|
accumbent |
= pleurorhizal |
arrangement |
cotyledons |
Having the two cotyledons facing and parallel (adaxial surfaces contiguous) and recurved together, one lateral edge of each abutting the hypocotyl and radicle. |
|
…whorled |
= …cyclic, …seriate, …verticillate |
arrangement |
|
Disposed in the number of whorls (cycles, series, verticils) indicated by the prefix; as in three-whorled, 1-whorled. |
|
elliptic(al) 1 |
|
arrangement |
bundle scars |
Forming an ellipse |
|
rosulate |
= rosetted |
arrangement |
leaves |
Forming a rosette; strongly congested and disposed radially about the main stem at or very near its base, seeming to arise at the same level and often overlapping laterally; esp. in perennial herbs. |
|
notorhizal |
= incumbent |
arrangement |
cotyledons |
Adaxially contiguous and reflexed parallel to the hypocotyl and radicle, the abaxial surface of one lying against them. |
|
duplicate 1 |
= conduplicate |
arrangement |
cotyledons |
Adaxially contiguous, folded sharply together longitudinally (one adaxially, one abaxially), and reflexed together, one enveloping the hypocotyl and radicle, the other enveloping the first. |
|
tetradal |
|
arrangement |
pollen |
Shed in groups of four, each an intact tetrad with original configuration unchanged; geometric arrangement of the grains may be tetrahedral, tetragonal, or linear, depending upon mode of pollen mother cell division. |
|
distant |
= remote |
arrangement |
|
Disposed relatively far from one another along the axis. |
|
semicircular |
|
arrangement |
bundle scars |
Forming an incomplete circle, like the letter C. |
|
solitary 1 |
|
arrangement |
|
Disposed singly, each remote from any others. |
