Angophora is a genus of nine species of trees and shrubs in the myrtle family, Myrtaceae. endemism to eastern Australia, they differ from other in having juvenile and adult leaves arranged in opposite pairs, reduced to projections on the edge of the Hypanthium, four or five overlapping, more or less round , and a papery or thin, woody, often strongly ribbed capsule. Species are found between the Atherton Tableland in Queensland and south through New South Wales to eastern Victoria, Australia.
Description
Plants in the genus
Angophora are trees, occasionally shrubs, with rough bark except for
A. costata. The juvenile leaves differ from adult leaves in being hairy with raised oil glands. Both juvenile and adult leaves are arranged in opposite pairs, the adult leaves usually and paler on the lower surface. The flower buds are arranged in groups of three or seven. The flower has four or five small sepals, reduced to small projections on the rim of the floral cup. There are four or five more or less round, keeled, overlapping petals and whorls of many creamy white
. Unlike in
Eucalyptus and
Corymbia, the petals and sepals are not fused to form a cap-like operculum. The fruit is a papery or thin, slightly woody, hairy capsule with longitudinal ribs.
Taxonomy
The genus
Angophora was first formally described in 1797 by Antonio José Cavanilles in his book
Icones et Descriptiones Plantarum.
Angophora is closely related to Corymbia and Eucalyptus, and all three genera are often referred to as "eucalypts". Collectively the eucalypts dominate many Australian . Taxonomists have long recognised the relationships between the eucalypt taxa, but have not agreed upon a classification scheme. Some have proposed merging Angophora and Corymbia into genus Eucalyptus as Subgenus,[Brooker, M. I. H. (2000). A new classification of the genus Eucalyptus L'Her.(Myrtaceae). Australian Systematic Botany 13(1), 79–148.] a plan which was immediately rejected by others.[Ladiges, P. Y. and F. Udovicic. (2000). Comment on a new classification of the eucalypts. Australian Systematic Botany 13(1), 149–52.] Some authors maintain Angophora as a genus,[Steane, D. A., et al. (2001). Development and characterisation of microsatellite loci in Eucalyptus globulus (Myrtaceae). Silvae Genetica 50(2), 89–91.] while others continue to debate the issue.[Brummitt, R. K. (2003). Further dogged defense of paraphyletic taxa. Taxon 52(4), 803-04.][Nelson, G., et al. (2003). Brummitt on paraphyly: a response. Taxon 52(2), 295-98.]
Among the eucalypts, Angophora species were nicknamed "apples" by European settlers, who thought they resembled malus. Many are still known commonly as apples today.[
