c) 1 ' pair bifid ^leaf" seemingly a terminal leaflet, 2'' pair cup. 



d) „ „ normal, 2^ pair bifid „leaf". 



e) „ „ cup- shaped. 



IV. Terminal leaflet grown together with 

 one of the lateral ones. 



a) The rest of the folioles normal. 



b) 2'-^ pair grown together to a bifid „leaf", 3d pair cup-shap- 

 ed, 4^1' pair a bifid „leaf". 



In the above we have left out of consideration the fairly 

 frequent cases of alternation ot the folioles instead of opposi- 

 tion, of leaflets not appearing and similar irregularities which 

 so often occur. For completeness' sake we mention a case in 

 which two subsequent leaflets — consequently belonging to 

 different pairs — united their petiolules.

 the greater number of the species of the genus.
