A most lovely representative of one of the most variable 

 genera of hardy annuals, the limits between the species of 

 which are as difficult to draw from living specimens as from 

 herbarium ones. I have referred the subject of the present 

 plate to L. parvijlorus, though its flowers are so much larger 

 than those of the typical states of that plant, being able 

 to find no other difference but this of size (they are fully 

 twice as large as in most states of L. parviflorus) and of 

 colour, which however varies in the typical plant fi-om white 

 to lilac and yellow, and in this variety from a very pale to 

 a very deep rose-red. In respect to the size of the flower 

 October 1st, 1870.
