"With P. auricula I was unfortunate ; my few seedlings, except 

 one poor plant, all came up short-stj'led ; and of these plants 

 several died or became sick, owing to the hot weather and the dif- 

 ficulty of excluding insects and ventilating the corner of my green- 

 house enclosed with net. I finally got only two pods from one 

 union, and three from the other. The result is given in the 

 following table ; and, though worth little, we here again see that 

 the heteromorphic are far more fertile than the homomorpliio 

 unions.
