MACROBIOCARP Y IN AUSTRALIAN PLANTS. 
Fraulein Charlotte Kliem, Botanical Department of 
the University of Breslau, Gopperstrasze 6-8, Breslau, 
Germany, has written me to the effect that she is studying 
the phenomenon of macrobiocarpy. 
According to Delpino, who first studied the subject, 
macrobiocarps are those fruits that keep closed and fixed 
to the parent plants for a long time after the ripening of 
the seed without scattering them. This condition occurs 
particularly in the Australian flora, especially in the 
Myrtaceae, such as many species of Leptospermum, Calli- 
stemon, Kunzea, etc., and Proteaceae: Ilakea, Banksia, 
Dryandra, etc., and Casuarinaceae. 
Miss Kliem is very anxious to get hold of specimens 
from Australia and particularly notes from persons who 
have made any observations on this question. If they 
would write to her she would be very much obliged.
