calcarate |
= spurred |
base |
|

halberd-head-shaped 1 |
= hastate |
base |
laminar structure |

obtuse 2 |
= blunt |
base |
|
Bluntly angular; having an angular proximal portion whose generalized sides intersect at an angle of 90° or more. |
eared |
= auriculate |
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. |
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 |

conduplicate 1 |
= duplicate |
arrangement |
cotyledons |

= 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. |
