the two trees I experimented upon are not of the i)a わ： iral shape but

the formation of such abnormal flowers of Pinus densiflora takes place,

The main points to be deduced む om the above are as follows : 一

2. The sex of the flowers of Pinus densiflora is not determined 
by their morpho レ gical positio 打 s ou the shoot. 
3. The sex of the flowers is undetermined until a certain stage 
of their development.
