In extreme cases the chlorophyll becomes yellow or etiolated, and ceases to make starch altogether ; the plant then starves to Fig. 38.—Everlasting Pea with Leaf-Tendrils and Winged Stem. (Reduced.) The evolution of the climbing habit may be traced in several of our common British plants. The woody night- shade shows how an ordinary plant may become a twiner. The common fumitory {Fumaria officinalis), and its near relation, the climbing corydal (Corydalis claviculata), give us an idea of one method by which the tendril may be evolved. These two plants are occasional climbers, with large, much-dissected leaves. The leaflets are small, and the whole leaf appears to be more or less sensitive, so.
