Syn. 79. It seems quite easy to distinguish this from D. eu-verna 
in a book. The words, “pods once and a quarter to once anda 
half as long as broad” and “ pods twice or more times as long as 
broad,” read like a positive distinction. But this leaves only a 
distinction of one-half in the width relatively to the length, and 
I find in Surrey that variations of relative length from less than 
twice to more than thrice are intermediately connected by gradual 
transitions. I found, however, that some seeds of a short-podded 
form, brought from sterile gravel in Surrey, produced only the 
same short-podded form when sown in good garden mould. A 
second descent was not tried by re-sowing with the seeds produced 
in the garden; which would have been a better test.
