arrangement |
cells |

|
notorhizal |
= incumbent |
arrangement |
cotyledons |
Adaxially contiguous and reflexed parallel to the hypocotyl and radicle, the abaxial surface of one lying against them. |
|
contiguous |
|
arrangement |
|
Touching one another. |
|
radial |
= radiant, radiate, stellate |
arrangement |
|
Disposed about and mutually divergent from a common geometric center in two or three dimensions, thus collectively actinomorphic. |
|
…stichous |
= …ranked |
arrangement |
|
Disposed along the axis in the number of distinct ranks indicated by the prefix; as in distichous, polystichous, tristichous. |
|
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. |
|
arrowhead-shaped 1 |
= sagittate |
base |
laminar structure |
Having two retrorse, generally triangular lobes, one to either side. |
|
halberd-head-shaped 1 |
= hastate |
base |
laminar structure |
Having two generally triangular lobes, one to either side, oriented more or less perpendicular to the central axis. |
|
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. |
|
blunt 2 |
= obtuse |
base |
|
Bluntly angular; having an angular proximal portion whose generalized sides intersect at an angle of 90° or more. |
|
tailed 2 |
= caudate |
base |
|
With one or more relatively slender, retrorse basal enations or appendages. |
|
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. |
