Homalium brevidens

A shrub or tree species in the Salicaceae family, Homalium brevidens is found in Laos and Cambodia.
It grows 2-6m tall, with simple broad leaves, and is found in flooded forests in Cambodia.
These forests, also known as "swamp forests", is a community where the trees are usually 7-15(-20)m tall, that occurs along the shores of the lake Tonle Sap and nearby rivers, and is flooded to a maximum of 4-6m of water for up to 8 months per year. The 2 main species of tree in these forests are "Barringtonia acutangula" and "Diospyros cambodiana", with "H. brevidens" one of the other common tree species.
On islands of the Mekong, in Steung Treng and Kratie provinces, north-central Cambodia, the tree occurs with medium abundance in the Riverine Strand vegetation zone (last to be flooded, first to be exposed). Here it contributes to a closed canopy, growing above metamorphic sandstone bedrock at an elevation of 25-30m above sea level. On these islands it flowers from June to July, and fruits from September to October.
The plant is known as "rotèang" or "stiëw" in Khmer. Wood from the shrub is used to make charcoal, its bark is used to caulk boats.
