(Fig. 77), as in the Uvularia. In the Honeysuckles the opposite leaves are sometirnes united at their bases, rendering them con- nate-perfoliate (Fig. 78). The leaves of the Iris are equitant, that is, straddling over each other. Several kinds of leaves have no distinction of blade and petiole; as the sword-shaped, ensiform (Lat. ensis, sword), leaves of the Daflfodils; the needle-shaped, acicular (Lat. acus, needle), leaves of the Pines (Fig. 29); and the scale-shaped, squamose (Lat. squama, scale), leaves of the Junipers. If petioles become laminoid, or ex- panded like a blade, and take the place of the latter, they are called phyllodia. 43. The stipules are sometimes free, leaf-like append- ages, as in the Pea (Fig. 79), and perform the ordinary function of leaves; in Galium they are interpetiolar, and as large as the leaves and exactly resemble them, so that the leaves are usually said to be whorled; but in reality they are oppodtei the two intermediate leaves on each side being free stipules. Ordinarily, however, the stipules are very much reduced in size, as in the Bean ; sometimes they take the shape of bristles or prickles, as in the Locust (Fig. 80). In the Smilax they take on the shape of tendrils (Fig. 81). When united to the base of the Fig. 78. A Connate-perfoliate leaf. Fig. 79. Leaf of the Pea, with large,/r« stipules {slip)..
