Baeckea is a genus of flowering plants in the myrtle family, Myrtaceae, all but one endemic to Australia. Plants in the genus Baeckea are shrubs or small trees with leaves arranged in opposite pairs, white to deep pink flowers with five sepals and five petals, and five to fifteen stamens that are shorter than the petals.

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]

The names of 27 species of Baeckea have been accepted by Plants of the World Online as at January 2022: [12]

<i>Leptospermum</i> Genus of shrubs

Leptospermum is a genus of shrubs and small trees in the myrtle family Myrtaceae commonly known as tea trees, although this name is sometimes also used for some species of Melaleuca. Most species are endemic to Australia, with the greatest diversity in the south of the continent, but some are native to other parts of the world, including New Zealand and Southeast Asia. Leptospermums all have five conspicuous petals and five groups of stamens which alternate with the petals. There is a single style in the centre of the flower and the fruit is a woody capsule.

<i>Leucopogon</i> Genus of flowering plants

Leucopogon is a genus of about 150-160 species of shrubs or small trees in the family Ericaceae, in the section of that family formerly treated as the separate family Epacridaceae. They are native to Australia, New Zealand, New Caledonia, the western Pacific Islands and Malaysia, with the greatest species diversity in southeastern Australia. Plants in this genus have leaves with a few more or less parallel veins, and tube-shaped flowers usually with a white beard inside.

<i>Prostanthera</i> Genus of plants

Prostanthera, commonly known as mintbush or mint bush, is a genus of about 100 species of flowering plants in the mint family Lamiaceae, and all are endemic to Australia. Plants are usually shrubs, rarely trees with leaves in opposite pairs. The flowers are arranged in panicles in the leaf axils or on the ends of branchlets. The sepals are joined at the base with two lobes. The petals are usually blue to purple or white, joined in a tube with two "lips", the lower lip with three lobes and the upper lip with two lobes or notched.

<i>Kunzea</i> Genus of flowering plants

Kunzea is a genus of plants in the family Myrtaceae and is endemic to Australasia. They are shrubs, sometimes small trees and usually have small, crowded, rather aromatic leaves. The flowers are similar to those of plants in the genus Leptospermum but differ in having stamens that are longer than the petals. Most kunzeas are endemic to Western Australia but a few occur in eastern Australia and a few are found in New Zealand. The taxonomy of the genus is not settled and is complicated by the existence of a number of hybrids.

<i>Homoranthus</i> Genus of flowering plants

Homoranthus is a genus of about thirty species of plants in the myrtle family Myrtaceae and all are endemic to Australia. Plants in this genus share similarities with those in both Darwinia and Verticordia. They are shrubs with their leaves arranged in opposite pairs and with flowers appearing either singly or in small groups, usually in upper leaf axils. They are found in Queensland, New South Wales and South Australia. The genus was first described in 1836. None of the species is common nor are they well-known in horticulture.
