. MENDELS "LAW APPLIED TO ORCHID HYBRIDS. 



691 



more I will term A. Likewise, all those that show | a and Tnore, I will 

 term a. 



The remainder, lying between | A and | a, I will term " intermediate " 

 or A a. 



I admit that this classifieation is far from perfect, but it seems to be 

 sufficiently precise for practical purposes. 



Following out this classification, I have carefully analysed the 

 inheritance of pairs of specific characters in many distinct hybrids 

 belonging to several genera in the OrcJiicIece. 



In all cases I have been careful to actually compare the hybrids with 

 their parents, mostly from living plants in my own collection, others 

 from photographs or reliable coloured drawings. For the sake of clear- 

 ness, I will repeat that, according to Mendel's system, single characters 

 only are dealt with in a number of plants, 'the individual plant made up 

 of many characters in this case being ignored as a unit, though at the . 

 same time the many specific characters of a plant have been utilised 

 separately in the analyses to make up the result. 



The following is a detailed list of the analyses, giving — 



(1) The name of the hybrid. 



(2) The names of the parents. 



(3) The numbers of the "specifics " — i.e. those characters that in the 

 analyses are classed as either A or a. 



(4) The numbers of the " intermediates " — i.e. those characters that 

 in the analyses are classed as Aa.
