Mr. Buchanan states that 
neither the clumps of 
Cephalostachyum per¬ 
gracile nor Bambusa 
pallida are as yet mature, 
while those of Dendro¬ 
calamus Hamiltonii he 
classes as middle-aged.

Nora.—He proposes to carry out further experiments by thinning the dumps, in order to ascertain the effect of cutting out mature culms on the growth of new shoots. The results of these experiments, when completed oan be communicated, to any interested persons who care to make enquiries
