Or in a compound leaf, as in the Pea and most Vetches, and InCobsea, while the lower leaflets serve for foliage, some of the uppermostare developed as tendrils for climbing (Fig. 167). In the common Pea thisis so with all but one or two pairs of leaflets. 170. In one European Vetch, the leaflets are wanting and the wholepetiole is a tendril, while the stipules become the only foliage (Fig. 173). 171. Leaves as Pitchers, or hollow tubes, are familiar in the commonPitcher-plant or Side-saddle Flower (Sarracenia
