Stomates are very numeroiis, as will be seen from the num- bers showing the pores to each square inch of leaf surface : Peony . ... Holly . Lilac Mistletoe . Tradescautici Garden Flag (iris) . The arrangement of stomates on the leaf dijfers with each kind of plant. Fig. 116 shows stomates and also the outlines of contiguous epidermal cells. The function or work of the stomates is to regulate the passage of gases into and out of the plant. The directly active organs or parts are guard-cells, on either side the opening.
