same raceme, none of which produced capsules. In all other cases under this 

 head the flowers were pollinated with their own pollen : — 



Taking the totals of the above list, we find that 100 per cent, of the cross- 

 pollinated flowers formed capsules, while only 8 per cent, of the self- 

 pollinated flowers formed capsules. If we except the three species, B. senile, 

 D. tortile, and B. crepidatum, which, I will show below, liave certain peculiar 

 characteristics, then less than 3 per cent, of the self-pollinated flowers formed 

 capsules. 



The following are a few notes on some of the above-mentioned species : — 



Bendrohium cajnllipes. — Of the two flowers which are given above as 

 forming capsules after self-pollination, one dropped its capsule while still 

 green, so that really only one self-pollinated flower produced mature seeds. 

 The fertility of these seeds was not examined.
