126 THE SURVIVAL OF THE UNLIKE. [iV. 



this point, with illustrations, in Essay XXX.). When 

 this pear -form type becomes markedly augmented in 

 size, the distinctly clavate form tends to disappear, as 

 if the fruit were making the attempt to throw itself into 

 a spherical form. This is shown in the outer diagram 

 in H, which represents the King Humbert tomato. I 

 have already said that both the pear and cherry toma- 

 toes were formerly described as species — Lycopersicum 

 pyriforme and L. cerasiforme respectively. A picture 

 of the pear tomato, drawn from a figure in Dunal's 

 monograph, is shown in I. In J is shown a picture 

 of an authentic specimen of the cherry tomato. All 

 these various pictures, therefore — from A to J — repre- 

 sent forms of the common tomato species, Lycopersicum 

 esculentum. 



The reader will now be interested to compare with 

 these pictures of various forms of L. esculentum, those of 

 other accepted species of Lycopersicum. For this pur- 

 pose, I have had Mr. John Allen make drawings of 

 specimens in the Kew Herbarium, and these drawings 

 are here laid before the reader. I suppose that all the 

 specimens from which these drawings are made are 

 properly determined (many of them are truly authentic), 

 but I do not vouch for them, and I do not submit the 

 pictures for the purpose of making a contribution to the 

 knowledge of the species of Lycopersicum, but I intro- 

 duce them to show that the differences between the 

 various accepted species do not strike one as being so 

 marked or so valid as the differences between the various 

 groups of Lycopersicum esculentum itself. I first show a 

 spray of the Currant tomato, K, drawn from specimens 

 of my own growing, a .species to which T have already 

 adverted on pages 117, 118. L and M are evidently the
