I do not know if anyone previously explained why the plant You are not allowed to view links. Register or Login to view. has two tiers of roots.
My explanation is as follows.
Note that five plants have a head (thickening at the bottom of the stem), and four plants have no such thickening.
The artist tried to depict Curtin (bush), if to look at it just below the horizon. In this case, can not be seen "thickening" of plants that are in the background (red arrow), and vice versa, in these plants the roots fall into the field of vision, which forms in the picture the lower tier of the roots (dark green arrow).
