bundle scars |
Forming an incomplete ellipsis, like the letter U. |
|
fascicled 2 |
= bundled (not recommended), fasciculate |
arrangement |
|

|
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). |
|
divergent |
|
arrangement |
|
Directed at individually different angles from a common point or relatively limited zone of origin, thus farther apart distally than proximally. |
|
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. |
|
…angular 1 |
|
arrangement |
bundle scars |
Forming a figure with the number of sides indicated by the prefix. |
|
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. |
|
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. |
|
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. |
|
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. |
|
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. |
|
pseudomonadal |
|
arrangement |
pollen |
Apparently monadal but each grain actually comprising an unseparated original tetrad in which the contiguous walls between component grains have dissolved. |
|
fastigiate |
|
arrangement |
branches |
Closely parallel to one another and to the axis of origin over most of their lengths. |
|
linear 1 |
|
arrangement |
bundle scars |
Disposed in a more or less straight line. |
|
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. |
|
diplecolobal |
|
arrangement |
cotyledons |
Incumbent but with the cotyledons folded together twice or more, the folds transverse. |
|
spirolobal |
|
arrangement |
cotyledons |
Incumbent and folded together transversely. |
|
imbricate(d) 2 |
= overlapping |
arrangement |
planate structures |
Overlapping one another laterally and/or longitudinally. |
|
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. |
