ern Texas. Additional localities may yet be reported. The 

 hybrid, 5. areolata, with 5. Drummondii, is therefore to be 

 sought only between Alabama River and western Alabama. 

 It is especially plentiful at two points, Theodore, Alabama, 

 where it was first found, and Deer Park. 



The above are the species and hybrids selected for study. 

 The material used was from natural sources indicated above, 

 transplanted to the University of Pennsylvania Botanical 

 Garden. 



It might be well to note here the other natural hybrids re- 

 ported by various collectors. Besides the above three, there 



are given (23; 17): 

 5. flava X S. minor. 



S. minor X 5. psittacina (grown in University of Pennsylvania). 

 5. rubra X 5. Drummondii. 

 S. psittacina X S. purpurea. 



S. rubra X S. purpurea (grown in University of Pennsylvania). 

 5. Drummondii X S. purpurea (grown in University of Pennsylvania). 

 5. Sledgei X 5. purpurea (grown in University of Pennsylvania). 



The study was limited to three groups, with one parent com- 

 mon to two hybrids in order the better to ascertain the action 

 of a given parental characteristic. 



Comparison of Parents and Hybrids 



Set 1. S. purpurea, S. flava, and S. Catesbaei (S. Stevensii) 



A. Naked Eye Characters 



The general habit of 5. purpurea is shown well in PI. I, fig. i, 

 with its inflated pitchers, and the decumbent leaves. S. flava 

 presents a striking contrast to S. purpurea (PI. I, fig. 2). The 

 pitchers are erect, slender, and gradually expanded upwards. 

 In the hybrid (PI. I, fig. 3) the pitchers lean at an angle of 45 , 

 and are slightly inflated in their middle portion. 



In height the three forms present a wide range. S. purpurea, 

 the lowest, averages 12-15 cm., though specimens can be 

 found 35 cm. in length. S. flava may be from 20-100 cm. high, 

 but average pitchers measure 60-70 cm. from base to the tip 

 of the lid. The hybrid averages 24-36 cm. in length. 



The "wing," or fused laminar faces in front of the pitcher 

 proper, is wide in S. purpurea (PI. I, fig. 1) and tends to have 

 an undulating margin. In S. flava the wing is very narrow
