Not against the sun's rays, for it is only the under
surface that is coated. When the upper leaf surface is hairy, we
know that the plant is protected in this way from perspiring too
freely. Doubtless these leaves of the steeple bush, like those of
other plants that choose a similar habitat, have woolly hairs
beneath as an absorbent to protect their pores from clogging with
the vapors that must rise from the damp ground where the plant
grows. If these pores were filled with moisture from without, how
could they possibly throw off the waste of the plant? All plants
are largely dependent upon free perspiration for health, but
especially those whose roots, struck in wet ground, are
constantly sending up moisture through the stem and leaves.
