acyclic |

= overlapping |
arrangement |
planate structures |
Overlapping one another laterally and/or longitudinally. |
bundled 2 (not recommended) |

arrangement |
|
Disposed in one or more fascicles, the members of each inserted close together and only slightly if at all divergent from one another. |
polyadal |
|
arrangement |
pollen |
Shed in groups of more than four, each group comprising grains from two or more original tetrads, the latter intact or not. |
…stichous |
= …ranked |
arrangement |
|
Disposed along the axis in the number of distinct ranks indicated by the prefix; as in distichous, polystichous, tristichous. |
V-form |
|
arrangement |
bundle scars |
Disposed in an open-ended triangular pattern, like the letter V. |
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). |
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. |
superposed 1 |
|
arrangement |
|
Approximate to congested, inserted directly above and below one another. |
scalariform |
= ladder-like |
arrangement |
|
Disposed in vertical sequence with long axes horizontal and parallel. |
overlapping 2 |
= imbricate(d) |
arrangement |
planate structures |
Overlapping one another laterally and/or longitudinally. |
conjugate |
= geminate, paired |
arrangement |
|
Inserted by pairs, the members of each fused or not. |
…angular 1 |
|
arrangement |
bundle scars |
Forming a figure with the number of sides indicated by the prefix. |
brickwork-like |
= muriform |
arrangement |
cells |
Disposed like bricks in a wall; in parallel rows, the members in each row overlapping the boundaries between members of the adjacent rows. |
tiered |
|
arrangement |
|
In two or more rows that are arrayed one above another. |
muriform |
= brickwork-like |
arrangement |
cells |
Disposed like bricks in a wall; in parallel rows, the members in each row overlapping the boundaries between members of the adjacent rows. |
monadal |
|
arrangement |
pollen |
Shed singly, or essentially so, only loosely and irregularly, if at all, coherent, each original tetrad having separated fully. |
connivent |
|
arrangement |
|
Converging and distally contiguous; esp. arcuate stamens with anthers contiguous. |
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. |
geminate |
= conjugate, paired |
arrangement |
|
Inserted by pairs, the members of each fused or not. |
…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. |
decussate |
|
arrangement |
|
Opposite with successive pairs radially oriented at right angles to one another, thus polystichous with four equidistant ranks. |
radiant 2 |
= radial, radiate, stellate |
arrangement |
|
Disposed about and mutually divergent from a common geometric center in two or three dimensions, thus collectively actinomorphic. |
