Summary
Thanks CD for his letter of 21 June [13212].
Is sending seeds of Oxalis sepium, which came from a cross between a plant with long pistils and another with pistils intermediate in length. Perhaps some of the plants that come from them will have short pistils.
FM does not know who told Dr B [Wilhelm Breitenbach] that he had lost a whole library in the flood. In fact, he lost only a few books that he had left behind thinking they were safe where they were.
Has taken the opportunity of a recent cold spell to test CD’s views on nyctitropism [night movements] in plants. Describes Pandanus and Oxalis sepium.
Has just received CD’s letter of 4 July and he is glad that his observations on the effects of rain on plants interested CD.

Summary
Summarises the "remarkable facts about the movements of plants" in Fritz Müller’s letter of January [12996]. CD comments that Müller’s observations support the conclusion that he and Francis Darwin arrived at – that leaves go to sleep to escape the full effects of radiation.

From Fritz Müller 31 May 1881
Summary
Has just received CD’s letter of 12 April [13113]. To answer CD’s query, Heteranthera reniformis is an amphibious plant that grows as well on moist ground as it does in ditches filled with water.
For the past few weeks has been observing Phyllanthus plants that had shown the irregular movement in leaves returning from the positions assumed at night, but none has repeated the irregularity. Perhaps the progeny from the seeds he has collected will inherit the tendency for irregular movement.
Describes his observations of the power of movement in Cassia, Desmodium, and a few other plants.
Paul Mayer has identified seven new species of insects FM found in nine different species of figs.

Summary
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.
