Sannantha pluriflora
Sannantha pluriflora, commonly known as tall baeckea, is a species of flowering plant in the myrtle family, Myrtaceae, and is endemic to continental southeastern Australia. It is a shrub or small tree with lance-shaped to elliptic leaves, and groups of two to nine white flowers arranged in umbels in leaf axils.

Description
Sannantha pluriflora is an erect shrub or small tree that typically grows to a height of  and has branchlets that are more or less square in cross-section. The leaves are lance-shaped to elliptic,  long and  wide on a petiole  long. The leaves have prominent oil glands, especially on the lower surface. The flowers are up to  in diameter and arranged in umbels of two to nine in leaf axils on a peduncle  long. Each flower is on a pedicel  long with linear bracteoles up to  long at the base. The floral tube is more or less smooth, the sepal lobes up to  long. The petals are white and broadly egg-shaped to round,  long and there are 8 to 15 stamens. Flowering mainly occurs from October to January and the fruit is a capsule  in diameter.

Taxonomy
This species was first formally described in 1855 by Victorian Government Botanist Ferdinand von Mueller who gave it the name Camphoromyrtus pluriflora in his Definitions of rare or hitherto undescribed Australian plants. In 2007, Peter Gordon Wilson placed it in the newly created genus Sannantha as S. pluriflora in Australian Systematic Botany.

In 1775, Johann and Georg Forster described Leptospermum virgatum in Characteres Generum Plantarum and in 1810, Henry Cranke Andrews transferred the species to Baeckea as B. virgata, a name that was previously misapplied to the present species. In 1999, Anthony Bean revised B. virgata in the journal Austrobaileya, and that name is no longer accepted by the Australian Plant Census.

Distribution
Sannantha pluriflora mostly grows in forest near streams and is widespread on the coast and nearby tablelands of New South Wales south from Port Stephens to Gippsland in eastern Victoria.
