- This year (1918) almost all the offspring derived from this fertilisation were found to 

 possess some buds containing young catkins, but many of the latter ceased to grow in their 

 very young stages, having been killed by the severe frosts of last winter, so that I was able 

 to ascertain in 18 tree.s only the type of catkins borne by each of them.
