RAISING NEW VARIETIES 53 



tained. This points to another method of cross-fertilisation 

 which has been successfully adopted. The blooms are 

 secured in an upright position to short sticks at an early 

 stage of their development. Held in this position, and 

 insects being excluded, they cannot become either cross 

 or self pollinated except by hand. If the desired pollen 

 is carefully applied to the viscid lip of the stigma at the 

 right time, a true cross is obtained without emasculation. 

 Raisers are working for new colours and improved habits, 

 and there is plenty of room for improvement in these 

 directions.
