The purple fluid or granular matter which fills the cells of the glands differs to a certain extent from that within the cells of the pedicels. For when a leaf is placed in hot water or in certain acids, the glands become quite white and opaque, whereas the cells of the pedicels are rendered of a bright red, with the exception of those close beneath the glands.
These latter cells lose their pale red tint; and the green matter which they, as well as the basal cells, contain, becomes of a brighter green.
