Such are the upper leaves of true Honey- suckles. Here (Fig. 163) of the opposite and sessile leaves, some pairs, especially the uppermost, in the course of their formation unite around the stem, which thus seems to run through the disk formed by their union. 160. Equitant Leaves. Wiiile ordinary leaves spread horizontally, and present one face to the sky and the other to the earth, there are some that present their tip to the sky, and their faces right and left to the horizon. Among these are the equitant leaves of the Iris or Flower-de-Luce. In- spection shows that each leaf was formed as \i folded together lengthwise, Fio. 162.
