Poplar

Poplar

Poplar Populus is a widespread genus in the northern hemisphere and there are around 35 species. Like their close relatives the willows, poplars have separate male and female trees and the flowers are borne in catkins which appear before the leaf buds open. Poplar catkins droop from the twigs looking rather like caterpillars. The male flowers of the poplars have more stamens than those of the willows. [CH] {NT}
