Fig. 15-3. Figures 1-3 represent composite two-dimensional chromatograms of leaf extracts 

 of Baptisia leucantha (upper left), B. sphaerocarpa (upper right), and B. leucophaea 

 (middle left). Figures 4-6 represent individual hybrids: B. leucophaea X B. leucantha 

 (middle right); B. leucophaea X B. sphaerocarpa (lower left); B. leucantha X B. 

 sphaerocarpa (lower right). 



Black spots represent compounds of doubtful value in the cases indicated (perhaps 

 characteristic of both parental species of a particular hybrid); dotted spots represent 

 species-specific but minor components which are useful when present; grey (or finely 

 stippled) spots represent major spots of greatest significance. La = B. leucophaea spots; 

 Le = B. leucantha spots; Y = B. sphaerocarpa spots and H = hybrid-specific spots.
