The status of Cecropia (Urticaceae) introductions in Malesia: addressing the confusion

Research confirms that two species of Cecropia (C. peltata and C. pachystachya) have naturalized and become invasive in parts of Malesia, including Singapore, Java, Indonesia, and Peninsular Malaysia, challenging previous assumptions about the region's introduced flora. While C. peltata was first documented in 1862–1868 at Buitenzorg (Indonesia), its exact source remains uncertain. The study also debunks earlier claims about a third species, C. palmata, which is not extant in Malesia. Using historical records and botanical documentation, the authors clarify the status of these invasive plants, providing critical insights for conservation efforts.
