NOTES ON SOME CURIOSITIES OF ORCHID BREEDING.

It is evident from this that any experiments undertaken to 

 test the influence of foreign pollen on the period of pod ripening 

 must be carried out under the same conditions of light and heat. 

 On looking through Mr. Young's records I found twenty plants 

 that had been crossed, which fairly well corresponded with the 

 above conditions. Each plant carried two pods (except one, and 

 that had three), which were both crossed at the same time, and 

 thus each pair of pods would be under fairly equal conditions 

 all round. I have tabulated the results as follows : — 



Each Pair crossed with the same Species or Hybrid.
