This title is, without doubt, the hardest of Darwin's scientific works to obtain in a Murray imprint. Only about 3000 were issued in the entire 19th Century and none were printed at all in the UK in the 20th Century, by any publisher, until facsimiles appeared in the 1960s. "This was an extension of the work on climbing plants to show that the same mechanisms hold good for flowering plants in general. It was another specialist book and seems to have sold fewer copies than any other, and was not reprinted in England after the year of Darwin's death until modern facsimilies appeared of the first thousand in 1966 and the second in 1969.
