This anatomical characteristic is perhaps closely related to the first, in that its purpose seems to be to utilize the cen- tral space as much as possible. This arrangement is also ad- vantageous in that it brings the vessels nearer the root-hairs which absorb the moisture from the soil. The vessels first formed (pri-.
