were crossed in the course of four seasons. I may 

 mention, as a mere curiosity, that if any one were to 

 raise hybrids between two trimorphio heterostyled 

 species, he would have to make 90 distinct unions in 

 order to ascertain their fertility in all ways ; and as he 

 would have to try at least 10 flowers in each case, he 

 would be compelled to fertilise 900 flowers and count 

 their seeds. This would probably exhaust the patience 

 of the most patient man.
