remote |
= distant |
arrangement |
|
Disposed relatively far from one another along the axis. |
opposite 1 |
|
arrangement |
|
Disposed in pairs along the axis, the members of each pair inserted at the same level across from one another. |
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). |
semielliptic |
|
arrangement |
bundle scars |
Forming an incomplete ellipsis, like the letter U. |
opposite 2 |
|
arrangement |
|
Having the members of each whorl inserted directly above and/or below those of the next adjacent whorl(s). See also antipetalous, antisepalous. |
subopposite |
|
arrangement |
|
Alternate but verging on opposite. |
spiral 1 |
= acyclic, helical |
arrangement |
|
Disposed helically about and along the axis, each on a different radius than the one(s) vertically adjacent. |
conjugate |
= geminate, paired |
arrangement |
|
Inserted by pairs, the members of each fused or not. |
linear 1 |
|
arrangement |
bundle scars |
Disposed in a more or less straight line. |
geminate |
= conjugate, paired |
arrangement |
|
Inserted by pairs, the members of each fused or not. |
pseudomonadal |
|
arrangement |
pollen |
Apparently monadal but each grain actually comprising an unseparated original tetrad in which the contiguous walls between component grains have dissolved. |
U-form |
|
arrangement |
bundle scars |
Disposed in a truncated elliptical pattern, like the letter U. |
…ranked |
= …stichous |
arrangement |
|
Disposed along the axis in the number of distinct ranks indicated by the prefix; as in two-ranked. |
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. |
spirolobal |
|
arrangement |
cotyledons |
Incumbent and folded together transversely. |
imbricate(d) 2 |
= overlapping |
arrangement |
planate structures |
Overlapping one another laterally and/or longitudinally. |
connivent |
|
arrangement |
|
Converging and distally contiguous; esp. arcuate stamens with anthers contiguous. |
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. |
decussate |
|
arrangement |
|
Opposite with successive pairs radially oriented at right angles to one another, thus polystichous with four equidistant ranks. |
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. |
elliptic(al) 1 |
|
arrangement |
bundle scars |
Forming an ellipse |
V-form |
|
arrangement |
bundle scars |
Disposed in an open-ended triangular pattern, like the letter V. |
contiguous |
|
arrangement |
|
Touching one another. |
alternate 2 |
|
arrangement |
structures in multiple whorls |
Having those of each whorl staggered radially in relation to those of the adjacent whorl(s). |
…stichous |
= …ranked |
arrangement |
|
Disposed along the axis in the number of distinct ranks indicated by the prefix; as in distichous, polystichous, tristichous. |
