Monoon longifolium

Monoon longifolium, the false ashoka, also commonly known by its synonym Polyalthia longifolia, is an Asian small tree species in the family Annonaceae. It is native to southern India and Sri Lanka, but has been widely introduced elsewhere in tropical Asia. This evergreen tree is known to grow over 20 m. in height and is commonly planted due to its effectiveness in alleviating noise pollution. It exhibits symmetrical pyramidal growth with willowy weeping pendulous branches and long narrow lanceolate leaves with undulate margins.

Monoon longifolium is sometimes incorrectly identified as the ashoka tree (Saraca indica) because of the close resemblance of both trees. The cultivated, column-like pendula form can appear to have no branches, but in fact a non-hybrid M. longifolium allowed to grow naturally (without trimming the branches out for decorative reasons) grows into a normal large tree giving plenty of shade.
