|
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. |
|
circular |
|
arrangement |
bundle scars |
Forming a circle. |
|
convolute 2 |
|
arrangement |
cotyledons |
Each rolled or folded inward longitudinally, one enveloping the other. |
|
overlapping 2 |
= imbricate(d) |
arrangement |
planate structures |
Overlapping one another laterally and/or longitudinally. |
|
imbricate(d) 2 |
= overlapping |
arrangement |
planate structures |
Overlapping one another laterally and/or longitudinally. |
|
U-form |
|
arrangement |
bundle scars |
Disposed in a truncated elliptical pattern, like the letter U. |
|
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. |
|
V-form |
|
arrangement |
bundle scars |
Disposed in an open-ended triangular pattern, like the letter V. |
|
scalariform |
= ladder-like |
arrangement |
|
Disposed in vertical sequence with long axes horizontal and parallel. |
|
paired |
= conjugate, geminate |
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. |
|
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. |
|
…ranked |
= …stichous |
arrangement |
|
Disposed along the axis in the number of distinct ranks indicated by the prefix; as in two-ranked. |
|
…verticillate |
= …cyclic, …seriate, …whorled |
arrangement |
|
Disposed in the number of verticils (cycles, series, whorls) indicated by the prefix; as in five-whorled, 3-whorled. |
|
stellate 1 |
= radiant, radiate |
arrangement |
|
Disposed about and mutually divergent from a common geometric center in two or three dimensions, thus collectively actinomorphic. |
|
ladder-like |
= scalariform |
arrangement |
|
Disposed in vertical sequence with long axes horizontal and parallel. |
|
seriate |
= cyclic, verticillate, whorled |
arrangement |
|

|
arrangement |
bundle scars |
Forming an ellipse |
|
incumbent 1 |
= notorhizal |
arrangement |
cotyledons |
Adaxially contiguous and together oppositely parallel to the hypocotyl and radicle, the abaxial surface of one lying against them. |
