Note 7 — Chapter IX · SENSITIVENESS OF PLANTS TO LIGHT: ITS TRANSMITTED EFFECTS.
Reading edition
Emil Godlewski has given (‘Bot. Zeitung,’ 1879, Nos. 6–9) an excellent account (p. 120) of the present state of the question. See also Vines in ‘Arbeiten des Bot. Inst. in Würzburg,’ 1878, B. ii. pp. 114–147. Hugo de Vries has recently published a still more important article on this subject: ‘Bot Zeitung,’ Dec. 19th and 26th, 1879.
