Strobocalyx arborea, formerly widely known by the synonym Vernonia arborea, is a species of mid-level rainforest tree in the Composite, or Daisy family Asteraceae, that is found from the Western Ghats of India and Sri Lanka, east to the East Indies and New Guinea. [1] [2] This tree, and Brachylaena , are contenders for the tallest of all composite trees ("daisy trees"); plants on Sumatra (formerly distinguished as V. a. var. pilifera; locally called Maremboeng) reaching a height of 36 m (118 ft), and plants from Java (formerly distinguished as V. a. var. javanica; locally called Semboeng Kebo) can be almost as tall, to 34 m (112 ft), and at up to 104 cm (41 in) trunk diameter, is the most massive of all composites. [3] Its leaves contain a useful fungicide. [4] The leaves are alternate, ovate (but often asymmetrical), 8–25 cm long and 3–10 cm broad, with a leathery texture. [5]
