Opercularia vaginata (dogweed) is a species of plant within the genus Opercularia , in the family Rubiaceae. It is endemic to the southwest of Western Australia. [4]
O. vaginata is a spreading or erect perennial which grows to a height of 0.45 m on sandy, granitic and lateritic soils, and coastal limestone. [5] Its green or green-yellow flowers are seen from July to December. [5]
It is found in Beard's provinces of Eremaean Province and the South-West Province, or the later classification of IBRA regions of Avon Wheatbelt, Coolgardie (biogeographic region), Esperance Plains, Gascoyne, Geraldton Sandplains, Jarrah Forest, Mallee (biogeographic region), Murchison (biogeographic region), Swan Coastal Plain, Warren and Yalgoo (biogeographic region). [5]
It was first described by Jacques Labillardiere in 1804 as Opercularia vaginata in de Jussieu's Annales du Muséum d'histoire naturelle. [1] [2]
Antoine Laurent de Jussieu was a French botanist, notable as the first to publish a natural classification of flowering plants; much of his system remains in use today. His classification was based on an extended unpublished work by his uncle, the botanist Bernard de Jussieu.
The Monimiaceae is a family of flowering plants in the magnoliid order Laurales. It is closely related to the families Hernandiaceae and Lauraceae. It consists of shrubs, small trees, and a few lianas of the tropics and subtropics, mostly in the southern hemisphere. The largest center of diversity is New Guinea, with about 75 species. Lesser centres of diversity are Madagascar, Australia, and the neotropics. Africa has one species, Xymalos monospora, as does Southern Chile. Several species are distributed through Malesia and the southwest Pacific.
Southwest Australia is a biogeographic region in Western Australia. It includes the Mediterranean-climate area of southwestern Australia, which is home to a diverse and distinctive flora and fauna.
Jacques-Julien Houtou de Labillardière was a French biologist noted for his descriptions of the flora of Australia. Labillardière was a member of a voyage in search of the La Pérouse expedition. He published a popular account of his journey and produced the first Flora on the region.
Banksia ser. Dryandra is a series of 94 species of shrub to small tree in the plant genus Banksia. It was considered a separate genus named Dryandra until early 2007, when it was merged into Banksia on the basis of extensive molecular and morphological evidence that Banksia was paraphyletic with respect to Dryandra.
Banksia nivea, commonly known as honeypot dryandra, is a species of rounded shrub that is endemic to Western Australia. The Noongar peoples know the plant as bulgalla. It has linear, pinnatipartite leaves with triangular lobes, heads of cream-coloured and orange or red flowers and glabrous, egg-shaped follicles.

The flora of Western Australia comprises 10,842 published native vascular plant species and a further 1,030 unpublished species. They occur within 1,543 genera from 211 families; there are also 1,335 naturalised alien or invasive plant species more commonly known as weeds. There are an estimated 150,000 cryptogam species or nonvascular plants which include lichens, and fungi although only 1,786 species have been published, with 948 algae and 672 lichen the majority.

The botanical provinces of Western Australia (or Beard's Provinces) delineate "natural" phytogeographic regions of WA, based on climate and types of vegetation. John Stanley Beard, in "Plant Life of Western Australia" (p. 29-37) gives a short history of the various mappings.
