Usually the two are separate, but they mav be united with the leaf base itself, forming wings for it, as in roses (fig. 139), or they may be united with one another so as to form a sort of sheath encircling the stem (fig. 140). '\^'hen the leaf base is winged, the wings extend downward as lobes more or less encircling the stem. In many cases the leaf is said to be clasping (fig. 141 1. These lobes may even imite on the other side of the stem, so that the stem seems to penetrate the base of the blade. (See fig. 142.) '\\'hen two leaves occur at the same node, corresponding lobes of the.
