Tracing much magnified, re- duced to half of original size. Plant illuminated feebly from above. (7.) Euhus idceus (hybrid) (EosaceiB, Fam. 76).—As we hap- Fig. 75. pened to have a young plant, 11 inches in height and growing vigorously, which had been raised from a cross between the raspberry (Rubus idmus) and a North American Eubus, it was observed in the usual manner. During the morning of March 14th the stem almost completed a circle, and then moved far to the right. At 4 it reversed its course, nnd now a fresh tracing was begun, which was con- tinued during iOh h., and is given in Fig. 74. We here have well-marked circumnutation. (8.) Deutzia grarilis (Saxifragese, Fam. 77).—A shoot on a bush about 18 inches in height was observed. The bead changed its course greatly eleven o.^um gracilis-. cireumnu- times in the course of 10 h. 30 m. tation of stem, itept in (Fig. 75), and there could be no doubt about the circumnutation of the Btein. (9.) Fuchsia (grienhouse vaiv, with large flowers, probably a hybrid) (Ona- grariese, Fam. 100).—A young plant, 15 inches in height, was observed during nearly 48 h. The.
