dyadal |
|
arrangement |
pollen |
Cohering and shed in pairs, each tetrad having separated into halves. |
divergent |
|
arrangement |
|
Directed at individually different angles from a common point or relatively limited zone of origin, thus farther apart distally than proximally. |
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. |
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. |
…seriate 2 |
= …cyclic, …verticillate, …whorled |
arrangement |
|
Disposed in the number of series (cycles, verticils, whorls) indicated by the prefix; as in biseriate, 3-seriate. |
fascicled 2 |
= bundled (not recommended), fasciculate |
arrangement |
|
Disposed in one or more fascicles, the members of each inserted close together and only slightly if at all divergent from one another. |
V-form |
|
arrangement |
bundle scars |
Disposed in an open-ended triangular pattern, like the letter V. |
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. |
diplecolobal |
|
arrangement |
cotyledons |
Incumbent but with the cotyledons folded together twice or more, the folds transverse. |
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. |
fasciculate 2 |
= bundled (not recommended), fascicled |
arrangement |
|
Disposed in one or more fascicles, the members of each inserted close together and only slightly if at all divergent from one another. |
fastigiate |
|
arrangement |
branches |
Closely parallel to one another and to the axis of origin over most of their lengths. |
conjugate |
= geminate, paired |
arrangement |
|
Inserted by pairs, the members of each fused or not. |
intricate |
|
arrangement |
|
Entangled; irregularly intertwined and not readily disentangled. |
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. |
obvolute 1 |
|
arrangement |
cotyledons |
Having each cotyledon folded inward longitudinally, the two facing one another with their edges overlapping alternately (each enveloping one side or the other). |
semicircular |
|
arrangement |
bundle scars |
Forming an incomplete circle, like the letter C. |
solitary 1 |
|
arrangement |
|
Disposed singly, each remote from any others. |
stellate 1 |
= radiant, radiate |
arrangement |
|
Disposed about and mutually divergent from a common geometric center in two or three dimensions, thus collectively actinomorphic. |
connivent |
|
arrangement |
|
Converging and distally contiguous; esp. arcuate stamens with anthers contiguous. |
verticillate |
= cyclic, seriate, whorled |
arrangement |
|
Disposed along the axis in groups of three or more, the members of each group (cycle, series, verticil, whorl) inserted regularly around the axis at the same level. |
close |
= approximate |
arrangement |
|
Disposed relatively near to one another. |
remote |
= distant |
arrangement |
|
Disposed relatively far from one another along the axis. |
