THE NATURAL HISTORY ON A GASWORKS 339
my memory with the list of plants in London's Natural History, I cannot
understand why this plant is not mentioned, although the Alexanders was
included, but which we did not see. I wonder!
A list of plants seen during this visit and during a further visit in June,
1956, is appended.
