148 BROOKLYN BOTANIC GARDEN MEMOIRS 
Our study was made on a population of 53 plants. Pedigree 
numbers from 0 to 39 inclusive represent the cross NV. alata < N. for- 
getiana; pedigree numbers 40 to 52 inclusive represent cross JN. for- 
getiana X N. alata. 
Each plant was selfed one or more times, and all proved abso- 
lutely self-sterile. Further each plant was back-crossed with pollen 
from a single plant of each of the parent species with complete success 
in every case. The plants used in this case were not the individuals 
that entered into the cross, however, for unfortunately these were 
not available.
