From 1600m in Central Guizhou Province, SW China, where it grew with various Rhododendron species, Hydrangea longipes, Holboellia, Quercus aliena and other nice things. It is almost impossible to key-out Styrax species from China with any accuracy so this remains an unidentidied species, though the masses of relatively large and fragrant white flowers in June make a species name almost superfluous. A small tree for lime free soil.
