Asteroxylon
Asteroxylon (meaning "star-shaped xylem") was a Lycophyta plant that lived during the Early Devonian period 396 ± 8 million years ago in North-East Scotland.

Asteroxylon had branching stems, which reached 12 mm in diameter and 40 cm in length, were erect, rising from a ground-running organ, from which also protruded underground "rhizoids" or "roots": these reached a depth of up to 20 cm below the surface.
