Gummy Resinous & Slimy secretions may be either intercellular passages (lined with special cells; or in tubes made of rows of special cells. Some plants have both forms of secretion holders; or one of two closely related plants may have the one cell, the other passages—
From which de B thinks that the 2 forms of secretion holders come to much the same thing —
There is a relationship between secretion-holders and milk tubes; where milk is present secretion-holders absent p 143
He thinks also that secretion-holders occur more frequently where epidermic glands absent
