Akuatik, eksotik, Hydrocharis, HydrocharitaceaeAbstrak
Aktivitas manusia menyebabkan terjadinya perpindahan suatu jenis tumbuhan asing dari daerah sebaran aslinya ke daerah baru, misalnya melalui jalur perdagangan tanaman hias. Salah satu jenis tumbuhan asing akuatik yang diperdagangkan sebagai tanaman hias di Pulau Jawa yaitu Hydrocharis laevigata (Humb. & Bonpl. ex Willd.) Byng & Christenh. dari suku Hydrocharitaceae. Penelitian ini dilakukan untuk mengkaji H. laevigata secara botani yang mencakup ciri morfologi, taksonomi, pemanfaatan, ekologi, dan potensinya sebagai tumbuhan asing invasif. Metode yang digunakan dalam studi ini berupa studi literatur dengan menelaah berbagai referensi ilmiah. Hasil telaah menunjukkan bahwa H. laevigata berasal dari kawasan Amerika Tengah dan Selatan. Secara morfologi, jenis ini dicirikan oleh perawakan berupa terna melayang, bertangkai daun pendek, helaian daun membundar telur melebar hingga membundar, aerenkim di bagian abaksial daun, bunga uniseksual, perhiasan bunga berwarna putih, benang sari berjumlah enam, tangkai sari saling berlekatan membentuk tabung, dan bunga betina tanpa daun mahkota bunga. Hydrocharis laevigata dimanfaatkan sebagai tanaman hias untuk akuarium dan kolam. Namun, keberadaannya di Pulau Jawa perlu diperhatikan. Hal tersebut karena jenis ini dilaporkan telah menginvasi Australia dan Afrika.
