contiguous |
|
arrangement |
|
Touching one another. |
|
radial |
= radiant, radiate, stellate |
arrangement |
|
Disposed about and mutually divergent from a common geometric center in two or three dimensions, thus collectively actinomorphic. |
|
…stichous |
= …ranked |
arrangement |
|
Disposed along the axis in the number of distinct ranks indicated by the prefix; as in distichous, polystichous, tristichous. |
|
divaricate |
|
arrangement |
|
Strongly divergent. |
|
spirolobal |
|
arrangement |
cotyledons |
Incumbent and folded together transversely. |
|
close |
= approximate |
arrangement |
|
Disposed relatively near to one another. |
|
divergent |
|
arrangement |
|
Directed at individually different angles from a common point or relatively limited zone of origin, thus farther apart distally than proximally. |
|
intricate |
|
arrangement |
|
Entangled; irregularly intertwined and not readily disentangled. |
|
radiant 2 |
= radial, radiate, stellate |
arrangement |
|
Disposed about and mutually divergent from a common geometric center in two or three dimensions, thus collectively actinomorphic. |
|
dyadal |
|
arrangement |
pollen |
Cohering and shed in pairs, each tetrad having separated into halves. |
|
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. |
|
cyclic |
= seriate, 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. |
|
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. |
|
radiate 2 |
= radial, radiant, stellate |
arrangement |
|
Disposed about and mutually divergent from a common geometric center in two or three dimensions, thus collectively actinomorphic. |
|
…cyclic |
= …seriate, …verticillate, …whorled |
arrangement |
|
Disposed in the number of cycles (series, verticils, whorls) indicated by the prefix; as in monocyclic, 3-cyclic. |
|
clustered 1 |
|
arrangement |
|
Disposed in one or more aggregates, the members of each inserted close together, thence widely divergent from one another. |
|
semielliptic |
|
arrangement |
bundle scars |
Forming an incomplete ellipsis, like the letter U. |
|
diplecolobal |
|
arrangement |
cotyledons |
Incumbent but with the cotyledons folded together twice or more, the folds transverse. |
|
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. |
|
approximate |
= close |
arrangement |
|
Disposed relatively near to one another. |
|
remote |
= distant |
arrangement |
|
Disposed relatively far from one another along the axis. |
|
equitant |
|
arrangement |
|
Alternate, distichous, basal, and congested, each conduplicate with its lateral edges overlapping and/or overlapped by those of the immediately adjacent one(s). |
|
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. |
|
overlapping 2 |
= imbricate(d) |
arrangement |
planate structures |
Overlapping one another laterally and/or longitudinally. |
