Obs. There are numerous varieties of the Garden Onion, 
which differ principally in the shape and colour of their 
bulbs; some of these are noticed by ancient authors, 
which I have now quoted above. The two varieties I 
have enumerated are the most remarkable, and I have 
no doubt but, upon further examination, they may prove 
to be distinct species. Var. /3, as far as I am acquainted, 
has never been seen in flower, although cultivated to some 
extent in culinary gardens, where it is called Underground 
or Potato Onion.
