The transcript of this letter is not yet available online.

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.
