apex |
|
Terminating abruptly in a short, hard point that is a continuation of vascular tissue. See also apiculate, mucronulate. |
|
sharp |

|
Having a distinct, fine, weak, hair-like portion or protrusion. |
|
bifurcate |
< forked, furcate |
apex |
|
Having two terminal, antrorse branches or divisions arising from a common point or level, like the prongs of a fork. |

…dentate 1 |
= …-toothed |
apex |
|
Generally truncate but with the number of antrorse, attenuate, distal lobes indicated by the prefix; as in tridentate. |
|
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. |
