arrangement |
planate structures |
Overlapping one another laterally and/or longitudinally. |

cells |
Disposed like bricks in a wall; in parallel rows, the members in each row overlapping the boundaries between members of the adjacent rows. |
|
decussate |
|
arrangement |
|
Opposite with successive pairs radially oriented at right angles to one another, thus polystichous with four equidistant ranks. |
|
conduplicate 1 |
= duplicate |
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. |
|
tiered |
|
arrangement |
|
In two or more rows that are arrayed one above another. |
|
monadal |
|
arrangement |
pollen |
Shed singly, or essentially so, only loosely and irregularly, if at all, coherent, each original tetrad having separated fully. |
|
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. |
|
radial |
= radiant, radiate, stellate |
arrangement |
|
Disposed about and mutually divergent from a common geometric center in two or three dimensions, thus collectively actinomorphic. |
|
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. |
|
…verticillate |
= …cyclic, …seriate, …whorled |
arrangement |
|
Disposed in the number of verticils (cycles, series, whorls) indicated by the prefix; as in five-whorled, 3-whorled. |
|
incumbent 1 |
= notorhizal |
arrangement |
cotyledons |
Adaxially contiguous and together oppositely 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. |
|
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. |
|
paired |
= conjugate, geminate |
arrangement |
|
Inserted by pairs, the members of each fused or not. |
|
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. |
|
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. |
|
alternate 1 |
|
arrangement |
|
Inserted singly along the axis, each at a different level and each diverging on a different radius than the ones next above and below. |
