Si)rays of maidenhair fern (see Fig. 22) show a remark- able amount of adjustment of the leaflets to the light side. Another group of fern-plants, known as club-mosses, has horizontal stems clothed with numerous very small leaves. These leaves may be seen taking advantage of all the space on the lighted side (see Fig. 21),.
