With P. auricula I was unfortunate ; my few seedlings, except 
one poor plant, all came up short-styled ; 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 beteromorphic are far more fertile than the homomorphic 
unions.
