SOME NOTES ON THE POLLINATION OF 



FLOWERS IN THE BOTANIC GARDENS, 



SINGAPORE, AND IN OTHER PARTS 



OF THE MALAY PENINSULA. 



The daily round in the Botanic Gardens, Sino^apore, with 

 visits of inspection to Penang or to other places in the Peninsula 

 have afforded scattered opportunities during seven years, of making 

 notes upon the behaviour of insects in regard to flowers. These 

 notes will be brought into one view here.
