 | Black poplars are associated with alluvial soils in river valleys and floodplains generally south of a line from the Mersey to the Humber, with particular concentrations across the Midlands from the Welsh Marches to East Anglia (Milne-Redhead 1990) and notably in the Vale of Aylesbury (Mabey 1996). |
 | This spreading habit is dramatically different from the elongated shape of the Lombardy poplar (Populus nigra "Italica") that, surprisingly, is a cultivated variety of the fl poplar that was imported to Essex from Turin in 1758 (Elwes and Henry 1913, 7:1705-1806) and widely planted because of its unusual shape. |
 | Poplars are unusual in that there are separate male and female trees rather than both types of flower being on the one tree or the flowers containing both male stamens (with the pollen) and female ovaries. |
