Triplarina imbricata
Triplarina imbricata, commonly known as creek triplarina, is a species of flowering plant in the myrtle family, Myrtaceae and is endemic to northern New South Wales. It is a shrub with weeping branches, narrow egg-shaped leaves, and flowers in pairs with five sepals, five relatively small white petals and fourteen to seventeen stamens. Description. "Triplarina imbricata" is a shrub that typically grows to a height of up to and has a grey, scaly or fibrous bark. The leaves are narrow egg-shaped with the narrower end towards the base, long and wide on a petiole long. The  flowers are arranged in leaf axils in pairs on a peduncle long. Each flower is about in diameter with bracts about long. The sepal lobes are long and wide and have oil dots. The petals are white, more or less round, long and wide. There are fourteen to seventeen stamens on filaments about long and the ovary has three locules. Flowering has been recorded in November and December and the fruit is a hemispherical capsule long and wide. Taxonomy and naming. This species was first formally described by James Edward Smith in 1802 and given the name "Leptospermum imbricatum" in  the "Transactions of the Linnean Society of London" from specimens collected in 1791 by David Binton near Port Jackson. In 1826, John Sims described the species as "Baeckea camphorata" in the "Botanical Magazine" from an unpublished description by Robert Brown, but noted that "this species [has] as good a right to rank with "Leptospermum" as with "Baeckia", which has been considered to have five or eight stamens". In 1838, Rafinesque described the genus "Triplarina", changing the name "Baeckea camphorata" to "Triplarina camphorata" in his book "Sylva Telluriana", noting it had "fifteen stamens". In 1843, Schauer, apparently unaware of Rafinesque's  publication, described "Camphoromyrtus brownii", also based on "B. camphorata" in "Linnaea: ein Journal für die Botanik in ihrem ganzen Umfange, oder Beiträge zur Pflanzenkunde" but the name was illegitimate. In 1995, Anthony Bean reinstated the genus "Triplarina", based the name "T. imbricata" on Sims's "Leptospermum imbricatum", and considered "Baeckea camphorata" to be a synonym of "Triplarina camphorata". Distribution and habitat. This triplarina occurs in the Tabulam and Nymboida districts where it grows in heath, often in damp places. Conservation status. "Triplarina imbricata" is classified as "endangered" under the Australian Government "Environment Protection and Biodiversity Conservation Act 1999" and the  New South Wales Government "Biodiversity Conservation Act 2016". The main threats to the species include habitat loss, weed invasion and trampling by domestic livestock.
