Medium-sized tree with mainly an excurrent trunk and horizontal branches.
An excurrent and returning current were also traced to each of the legs.
But this tree of evolution is an excurrent stem, continuous through the clustering branches to the terminal shoot—man.
Its excurrent branches are very different from those of other elms.
Achenes top-shaped, 5-costate, villous; pappus of 5–10 long thin scales, awn-tipped by the excurrent nerve.
When the main trunk of a tree extends upward through the head to the tip, as in Fig. 3, it is said to be excurrent.
This is called an excurrent trunk (Lat., excurrere, to run out).
