CD interested by FM’s facts on movement of plants; has sent some to Nature ["Movement of leaves", Collected papers 2: 228–9]. Greatly admires FM’s work. Suggests an experiment to investigate movement in Phyllanthus.

Describes variability in the stamens and pollen of Lagerstroemia, which CD spoke of in Forms of flowers.
Also reports on similar phenomena in Pontederiacea (Heteranthera reniformis).
Has received from Paul Mayer an interesting paper on metamorphosis in Palaemonetes varians, which is also being studied by J. E. V. Boas in Denmark. Shows differences between larval development in Danish forms and those found in southern Italy.
In his last letter FM told CD about four flowers of Lagerstroemia that he had fertilised with the yellow pollen of another variety or species and which had subsequently fallen off. He has now repeated the experiment using the yellow pollen of a different variety and successfully produced good fruit as large as that fertilised with green pollen.
