Hibiscus tiliaceus, commonly known as the sea hibiscus or coast cottonwood, is an evergreen species of flowering tree in the mallow family, Malvaceae, with a pantropical distribution along coastlines. It has also been introduced to Florida and New Zealand. It has been debated whether this species is native or introduced to Hawaii.
Names
Common names include sea hibiscus, beach hibiscus, coastal (or coast) hibiscus, coastal (or coast) cottonwood, green cottonwood, native hibiscus, native rosella, cottonwood hibiscus, kurrajong, sea rosemallow and dhigga (Maldivian).
The plant was introduced by Austronesian peoples that voyaged across Southeast Asia and Oceania as a source of wood and fibre. This is reflected in the names of the plant as spoken in many related languages spoken in those regions including balibago (Tagalog),
malobago (Bikol), malabago or malbago (Cebuano – Southern), maribago (Cebuano – Northern), lambago (Cebuano - Cagayan de Oro), waru (Sundanese & Javanese), varo (Malagasy), baru or bebaru (Malay), pagu (Chamorro), hau (Hawaiian), fau (Samoan), purau (Tahitian), and vau tree (Vietnamese). The specific epithet, "tiliaceus", refers to its resemblance of the leaves to those of the related Tilia species.
