vexillate |
|
aestivation |
|
Having a larger member oriented more or less perpendicular to and folded about the others. |
|
induplicate |
|
aestivation |
|

|
corrugate 1 |
= crumpled |
aestivation |
|
Having members tightly and irregularly folded, the whole appearing as though wadded upon emergence. |
|
contorted 1 |
= convolute |
aestivation |
|
Imbricate and whorled, each member in turn overlapped by that to one side and overlapping that to the other, the whole tightly rolled and appearing as though twisted. |
|
contortuplicate 1 |
= torsive |
aestivation |
|
Plicate and contorted. |
|
carinal |
|
aestivation |
|
Having the petals of the keel (carina) enclosing the others. |
|
torsive |
= contortuplicate |
aestivation |
|
Plicate and contorted. |
|
overlapping 1 |
= imbricate(d) |
aestivation |
|
Having members whorled or spirally inserted and overlapping one another, each overlapping or overlapped to either side, and also above or below if spirally arranged or in multiple whorls. |
|
convolute 1 |
= contorted |
aestivation |
|
Imbricate and whorled, each member in turn overlapped by that to one side and overlapping that to the other, the whole tightly rolled and appearing as though twisted. |
|
imbricate(d) 1 |
= overlapping |
aestivation |
|
Having members whorled or spirally inserted and overlapping one another, each overlapping or overlapped to either side, and also above or below if spirally arranged or in multiple whorls. |
|
cochlear |
|
aestivation |
|
Imbricate with one member larger than and exterior to the others, parallel to one that is internal to all the others, strongly incurved, and enclosing the others. |
|
crumpled |
= corrugate |
aestivation |
|
Having members tightly and irregularly folded, the whole appearing as though wadded upon emergence. |
|
plicate 1 |
|
aestivation |
|
Valvate with each member strongly infolded longitudinally. |
|
conic(al) |
= cone-shaped |
apex |
|
Transversely round, essentially triangular in median longitudinal section, and broadest proximally. See also obconic(al). |
|
acuminate |
= concave-tapered |
apex |
|
Gradually diminishing in width or diameter to a slender tip, the sides longitudinally concave. Corresponds with attenuate for base shape. |
|
spinulose |
|
apex |
|
Finely spinose. |
|
acute |
= sharp |
apex |
|
Sharply angular; regularly and more or less straightly attenuate to an angular tip, the sides intersecting at an angle of less than 90°. |
|
uncinate |
= hamate, hooked |
apex |
|
Having a recurved terminal portion that resembles a hook. |
|
bifurcate |
< forked, furcate |
apex |
|
Having two terminal, antrorse branches or divisions arising from a common point or level, like the prongs of a fork. |
|
muticous |
|
apex |
|
Lacking a distinct terminal point (when one might be expected). |
|
emarginate |
= notched |
apex |
laminar structure |
Having a relatively small, acute, distal sinus. |
|
apiculate |
|
apex |
|
Terminating abruptly in a short, slender, angular tip that is not notably harder or stiffer than the main body of the structure. See also mucronate, mucronulate. |
|
lamellate |
|
apex |
laminar structure |
Having two small terminal plates of tissue closely parallel to one another and perpendicular to the plane of the lamina. |
