Family of mistletoes
Psittacanthus flowering atop a treeLoranthaceae , commonly known as theshowy mistletoes , is afamily offlowering plants .[ 2] [ 3] It consists of about 75 genera and 1,000 species ofwoody plants , many of themhemiparasites . The three terrestrial species areNuytsia floribunda (the Western Australian Christmas tree),Atkinsonia ligustrina (from theBlue Mountains of Australia), andGaiadendron punctatum (from Central/South America) Loranthaceae are primarilyxylem parasites, but theirhaustoria may sometimes tap thephloem ,[ 4] whileTristerix aphyllus is almostholoparasitic .[ 5] For a more complete description of the Australian Loranthaceae, seeFlora of Australia online Archived 2018-04-01 at theWayback Machine ,[ 2] for the Malesian Loranthaceae seeFlora of Malesia .
Originally, Loranthaceae contained allmistletoe species, but the mistletoes of Europe and North America (Viscum ,Arceuthobium , andPhoradendron ) belong to the familySantalaceae . TheAPG II system 2003 assigns the family to the orderSantalales in the cladecore eudicots .
Molecular phylogenetics suggests the following relationships of tribes, subtribes and genera:[ 6] [ 7] [ 8] [ 9] Nuytsia is sister to the rest of the Loranthaceae,[ 10] with many characters, including its pollen, its fruit (dry and three winged), and the number of itscotyledons , differing substantially from all other Loranthaceae genera.[ 5] The root parasitic habit is thought to be the basal condition of the family,[ 5] with the stem/branch parasitic habit evolving ca. 28-40 million years ago.[ 5] [ 11] However, Grimssonet al. (2017)[ 12] estimate this as occurring somewhat earlier (ca. 40-52 million years ago).
78 genera are accepted:[ 13]
