|
pollinial |
|
arrangement |
pollen |
Polyadal with the grains of individual thecae (pollen sacs), or of fused thecae, compacted and forming tightly coherent masses (pollinia) that constitute the basic dispersal units, these sometimes distally attenuate to a sterile caudicle (translator arm), sometimes united by caudicles in groups of two or more, the caudicle(s) sometimes attached to a viscidium, either directly or through an intervening stipe; esp. in Asclepiadaceae, Orchidaceae. |
|
conjugate |
= geminate, paired |
arrangement |
|
Inserted by pairs, the members of each fused or not. |
|
decussate |
|
arrangement |
|
Opposite with successive pairs radially oriented at right angles to one another, thus polystichous with four equidistant ranks. |
|
valvate 2 |
|
arrangement |
planate structures |
Not overlapping, adjacent members laterally contiguous at their margins. |
|
solitary 1 |
|
arrangement |
|
Disposed singly, each remote from any others. |
|
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. |
|
…angular 1 |
|
arrangement |
bundle scars |
Forming a figure with the number of sides indicated by the prefix. |
|
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. |
|
tiered |
|
arrangement |
|
In two or more rows that are arrayed one above another. |
|
acyclic |
= helical, spiral |
arrangement |
|
Disposed helically about and along the axis, each on a different radius than the one(s) vertically adjacent. |
|
…whorled |
= …cyclic, …seriate, …verticillate |
arrangement |
|
Disposed in the number of whorls (cycles, series, verticils) indicated by the prefix; as in three-whorled, 1-whorled. |
|
fastigiate |
|
arrangement |
branches |
Closely parallel to one another and to the axis of origin over most of their lengths. |
|
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. |
|
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. |
|
connivent |
|
arrangement |
|
Converging and distally contiguous; esp. arcuate stamens with anthers contiguous. |
|
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. |
|
superposed 1 |
|
arrangement |
|
Approximate to congested, inserted directly above and below one another. |
|
distant |
= remote |
arrangement |
|
Disposed relatively far from one another along the axis. |
|
spiral 1 |
= acyclic, helical |
arrangement |
|
Disposed helically about and along the axis, each on a different radius than the one(s) vertically adjacent. |
|
helical 1 |
= acyclic, spiral |
arrangement |
|
