In both of the species which I have mentioned as exhibiting the 
third type of andræcium, viz. P. fruticosa and P. rupestris, the number 
of stamens varies. In the festoons which the stamens form, however, 
five stamens occur with sufficient frequency to justify me in assuming 
25 to be the typical number of stamens in each flower. In one flower 
of P. fruticosa I observed a stamen superposed to one of the petals. 
This deviation, which is evidently rare, is very interesting, as showing 
an approach to the other types.
