Description
Plants in the genus Baeckea are glabrous shrubs, sometimes small trees, usually with the leaves arranged in opposite pairs or decussate. The flowers are usually arranged singly in leaf axils on a pedicel with two bracteoles at the base but that sometimes fall off as the flower opens. There are five sepals and five white to deep pink , more or less round petals that are free from each other. Five to fifteen stamens are arranged in a single row and are shorter that the petals and open by parallel slits. The fruit is a capsule containing many seeds.[2][3][4][5][6]
Taxonomy
The genus Baeckea was first formally described in 1753 by Carl Linnaeus in his Species Plantarum.[7][8] The genus is named in honor of the Swedish physician Abraham Bäck (or Baeck) (1713–1795).[9][10]
Many species formerly placed in the genus are currently included in Euryomyrtus, Harmogia, Kardomia, Oxymyrrhine, Rinzia, Sannantha, Seorsus and Triplarina.[3]
The closest genera to Baeckea are the fleshy-fruited Myrcianthes and Acmena, and the dry-fruited Angophora and Backhousia.[11]
Distribution and habitat
Species in the genus Baeckea are endemic to Australia, apart from B. frutescens that also occurs in Malesia.[2][12]
