Summary:

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.
