The presence of naturalized Alocasia cucullata (Lour.) G.Don (Araceae) in Java is reported for the first time in this paper. The species is an introduced ornamental plant native to India, Sri Lanka, and Indo-China and was only known in cultivation. In this study we collected samples from its naturalized populations in Sukabumi Regency (Cibadak Subdistrict) and Sumedang Regency (Jatinangor and Tanjungsari Subdistricts). The observed population grows along the roadside, coastal, ITB Jatinangor green space area, and palm oil plantation. In nature, A. cucullata may spread vegetatively either through root suckers, corms, and stem fragments. The description, distribution map, photographs, and a brief discussion are provided here.

We provide the occurrence data on five newly recorded alien Hydrocotyle Tourn. ex L. species (Araliaceae) in Java, namely H. acutiloba (F.Muell.) N.A.Wakef., H. bonariensis Comm. ex Lam., H. leucocephala Cham. & Schltdl., H. tripartita R.Br. ex A.Rich., and H. verticillata Thunb. Most species were introduced as ornamental plants and naturalized in Java. Hydrocotyle acutiloba and H. tripartita might have been accidentally introduced as soil contaminants during the Dutch Colonial Era, but both species had been misidentified as H. sibthorpioides. Descriptions, a key, distribution map, and images of the species are provided. [ABSTRACT FROM AUTHOR]
