apex |
|
Bearing one or more horns (cornicula). |
|
cone-shaped |
= conic(al) |
apex |
|
Transversely round, essentially triangular in median longitudinal section, and broadest proximally. See also obconic(al). |
|
corniculate |
= horned |
apex |
|
Bearing one or more cornicula (horns). |
|
spinose 1 |
|
apex |
|
Terminating in a rigid, tapering, sharp continuation of the central primary vein. See also spinulose. |
|
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. |
|
retuse |
|
apex |
|
Round overall with an obtuse terminal sinus. |
|
abrupt |
= truncate |
apex |
|
Having a distal boundary that is generally straight or plane and approximately perpendicular to the central axis. |
|
caudate 1 |
= tailed |
apex |
laminar structure |
Terminating in a relatively long, flexible, narrowly acuminate tip composed of laminar tissue. |
|
crested |
= cristate |
apex |
|
Having a laterally elongate, relatively thin, irregular or notched protrusion. |
|
aristate 1 |
= awned, bristled |
apex |
|

|
aristate 2 |
|
apex |
pappus scale |

|
notched |
= emarginate |
apex |
laminar structure |
