sharp |

mucronulate |
|
apex |
|
Finely mucronate. See also apiculate. |
piliferous |
|
apex |
|
Having a distinct, fine, weak, hair-like portion or protrusion. |
caudate 1 |
= tailed |
apex |
laminar structure |
Terminating in a relatively long, flexible, narrowly acuminate tip composed of laminar tissue. |
horned |
= corniculate |
apex |
|
Bearing one or more horns (cornicula). |
conic(al) |
= cone-shaped |
apex |
|
Transversely round, essentially triangular in median longitudinal section, and broadest proximally. See also obconic(al). |
small-beaked |
= rostellate |
apex |
|
Diminutively beaked (rostrate). |
bristled |
= aristate, awned |
apex |
|
Bearing one or more bristles (aristae, awns, setae). |
beaked |
= rostrate |
apex |
|
Terminating in a relatively long, tapering, more or less rigid point. See also small-beaked (rostellate). |
crested |
= cristate |
apex |
|
Having a laterally elongate, relatively thin, irregular or notched protrusion. |
oblique 1 |
|
apex |
|
Asymmetric about its longitudinal axis. |
blunt 1 |
= obtuse |
apex |
|
Bluntly angular; having an angular tip whose generalized sides intersect at an angle of 90° or more. |
retuse |
|
apex |
|
Round overall with an obtuse terminal sinus. |
acuminate |
= concave-tapered |
apex |
|
Gradually diminishing in width or diameter to a slender tip, the sides longitudinally concave. Corresponds with attenuate for base shape. |
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°. |
muticous |
|
apex |
|
Lacking a distinct terminal point (when one might be expected). |
uncinate |
= hamate, hooked |
apex |
|
Having a recurved terminal portion that resembles a hook. |
abrupt |
= truncate |
apex |
|
Having a distal boundary that is generally straight or plane and approximately perpendicular to the central axis. |
rostellate |
= small-beaked |
apex |
|
Diminutively rostrate (beaked). |
barbed 1 |
|
apex |
|
Terminated by a small, relatively stiff, acutely reflexed, hook-like structure. |
cuspidate |
|
apex |
|
Tapering gradually to a rigid tip composed of both vascular and laminar tissues. |
…-toothed 1 |
= …dentate |
apex |
|
Generally truncate but with the number of antrorse, attenuate, distal lobes indicated by the prefix; as in three-toothed. |
cristate |
= crested |
apex |
|
Having a laterally elongate, relatively thin, irregular or notched protrusion. |
tailed 1 |
= caudate |
apex |
laminar structure |
Terminating in a relatively long, flexible, narrowly acuminate tip composed of laminar tissue. |
rostrate |
= beaked |
apex |
|
Terminating in a relatively long, tapering, more or less rigid point. See also rostellate (small-beaked). |
