Is sending CD the seeds of a beautiful Cassia given to him by a friend. He sketched the unripe fruit a few months ago. This plant is rare in the area around Sta Catharina. He has found their largest and most beautiful butterfly Callidryas manippe near this tree and its caterpillars living on its leaves. Comments on how remarkable it is to find a species limited to living on a single tree in so large an area.

Summary:
Notes Julius Sachs’s opinion on the heliotropism of moulds: he can see no use in the response.
C. E. Stahl is working on swarm spores which can be made both helio- and apheliotropic.
Sachs has told him that some ferns sleep, and he suspects that some grasses may move.
Sachs also feels they may be working at bloom from a wrong point of view and suggests leaves may need to keep dry in order to keep their stomata open.
