…cyclic |
= …seriate, …verticillate, …whorled |
arrangement |
|
Disposed in the number of cycles (series, verticils, whorls) indicated by the prefix; as in monocyclic, 3-cyclic. |
|
clustered 1 |
|
arrangement |
|
Disposed in one or more aggregates, the members of each inserted close together, thence widely divergent from one another. |
|
semielliptic |
|
arrangement |
bundle scars |
Forming an incomplete ellipsis, like the letter U. |
|
diplecolobal |
|
arrangement |
cotyledons |
Incumbent but with the cotyledons folded together twice or more, the folds transverse. |
|
tetradal |
|
arrangement |
pollen |
Shed in groups of four, each an intact tetrad with original configuration unchanged; geometric arrangement of the grains may be tetrahedral, tetragonal, or linear, depending upon mode of pollen mother cell division. |
|
approximate |
= close |
arrangement |
|
Disposed relatively near to one another. |
|
remote |
= distant |
arrangement |
|
Disposed relatively far from one another along the axis. |
|
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). |
|
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. |
|
overlapping 2 |
= imbricate(d) |
arrangement |
planate structures |
Overlapping one another laterally and/or longitudinally. |
|
circular |
|
arrangement |
bundle scars |
Forming a circle. |
|
convolute 2 |
|
arrangement |
cotyledons |
Each rolled or folded inward longitudinally, one enveloping the other. |
|
rounded |
|
base |
|
Convex overall and more or less regularly curved. |
|
sheathing 2 |
|
base |
laminar structure |
Terete or involute and closely enclosing the supporting axis for some distance above the point of insertion. |
|
cordate 1 |
= heart-shaped |
base |
laminar structure |
Having two equal, more or less rounded, retrorse lobes, one to either side, overlapping or not, the intervening sinus relatively deep. |
|
concave-tapered 2 |
= attenuate |
base |
|
Gradually diminishing in width or diameter toward the proximal end, the sides longitudinally concave. Corresponds with acuminate for apex shape. |
|
truncate 2 |
|
base |
|
Having a generalized proximal boundary that is more or less straight or plane and approximately perpendicular to the central axis. |
|
hastate 1 |
= halberd-head-shaped |
base |
laminar structure |
Having two generally triangular lobes, one to either side, oriented more or less perpendicular to the central axis. |
|
spurred |
= calcarate |
base |
|
Having a relatively slender protrusion resembling a spur. |
|
oblique 1 |
|
base |
|
Asymmetric about its longitudinal axis. |
|
wedge-shaped 1 |
= cuneate, obtriangular |
base |
laminar structure |
Attenuate with the sides more or less straight and intersecting at an acute angle. |
|
attenuate 1 |
= concave-tapered |
base |
|
Gradually diminishing in width or diameter toward the proximal end, the sides longitudinally concave. Corresponds with acuminate for apex shape. |
|
cuneate 1 |
= obtriangular, wedge-shaped |
base |
laminar structure |
Attenuate with the sides more or less straight and intersecting at an acute angle. |
|
decurrent |
|
base |
laminar structure |
Having the lamina prolonged and adherent to the supporting axis beneath the point of vascular insertion, the prolonged portion termed a sterigma. |
|
auriculate |
= eared |
base |
laminar structure |
Having two small, rounded, lateral lobes, one to either side, that lie in more or less the same plane as the remainder of the lamina. |
