Sannantha similis is a species in the myrtle family, Myrtaceae and is endemic to eastern Australia. It is a shrub with narrowly lance-shaped leaves, and groups of three white flowers arranged in leaf axils.
Sannantha similis is a shrub that typically grows to a height of, its branchlets more or less square in cross-section. Its leaves are narrowly lance-shaped, long and wide on a petiole long. The flowers are in diameter and arranged in leaf axils in groups of three on a peduncle long, each flower on a pedicel long with narrowly triangular bracteoles up to long at the base. The floral tube is smooth, the sepal lobes up to about long. The petals are white, broadly elliptic to round, long and wide and there are 7 to 20 stamens. Flowering occurs from January to March, and the fruit is a capsule in diameter.[1] [2] [3]
This species was first formally described in 1997 by Anthony Bean who gave it the name Babingtonia similis in the journal Austrobaileya from specimens collected near Springbrook in 1994.[4] In 2007, Peter Gordon Wilson transferred the species to Sannantha as S. similis in Australian Systematic Botany.[5] The specific epithet (similis) means "like" or "resembling", referring to this species' similarity to Babingtonia angusta, (now Sannantha angusta).
This species was previously included in Baeckea virgata (J.R.Forst. & G.Forst.) Andrews.
Sannantha similis grows in a range of habitats, including open forest and rainforest margins, from near Brisbane in south-eastern Queensland to near Newcastle in New South Wales.
