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]
The Jardin des plantes, also known as the Jardin des plantes de Paris when distinguished from other jardins des plantes in other cities, is the main botanical garden in France. The term Jardin des plantes is the official name in the present day, but it is in fact an elliptical form of Jardin royal des plantes médicinales, which is related to the original purpose of the garden back in the 17th century.
The French National Museum of Natural History, known in French as the Muséum national d'histoire naturelle, is the natural history museum of France and a grand établissement of Sorbonne Universities. The main museum is located in Paris, on the left bank of the Seine. It was established in 1635 by King Louis XIII as the royal garden of medicinal plants, and in 1793, after the Revolution, it was reorganized in its present form and under its present title. As of 2017, the museum has 14 sites throughout France, including the original location at the Jardin des Plantes, which remains one of the seven departments of MNHN.

Cephalotus is a genus which contains one species, Cephalotus follicularis the Albany pitcher plant, a small carnivorous pitcher plant. The pit-fall traps of the modified leaves have inspired the common names for this plant, which include 'Albany pitcher plant", "Western Australian pitcher plant", "Australian pitcher plant", or "fly-catcher plant."
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.

Hakea petiolaris, commonly known as the sea-urchin hakea, is a shrub or small tree with cream-coloured and pink or purple flowers and woody fruit. It is endemic to the south west of Australia, occurring at the coastal plain, jarrah forest and wheatbelt regions, often at the ancient granite outcrops of Western Australia.

Esperance Plains, also known as Eyre Botanical District, is a biogeographic region in southern Western Australia on the south coast between the Avon Wheatbelt and Hampton regions, and bordered to the north by the Mallee region. It is a plain punctuated by granite and quartz outcrops and ranges, with a semi-arid Mediterranean climate and vegetation consisting mostly of mallee-heath and proteaceous scrub. About half of the region has been cleared for intensive agriculture. Recognised as a bioregion under the Interim Biogeographic Regionalisation for Australia (IBRA), it was first defined by John Stanley Beard in 1980.
Mallee, also known as Roe Botanical District, is a biogeographic region in southern Western Australia. Located between the Esperance Plains, Avon Wheatbelt and Coolgardie regions, it has a low, gently undulating topography, a semi-arid mediterranean climate, and extensive Eucalyptus mallee vegetation. About half of the region has been cleared for intensive agriculture. Recognised as a region under the Interim Biogeographic Regionalisation for Australia (IBRA), it was first defined by John Stanley Beard in 1980.

The flora of Western Australia comprises 10,252 published native vascular plant species and a further 1,245 unpublished species. They occur within 1,543 genera from 211 families; there are also 1,276 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.
Adenanthos obovatus, commonly known as basket flower, or, jugflower, is a shrub of the plant family Proteaceae endemic to Southwest Australia. Described by French naturalist Jacques Labillardière in 1805, it had first been collected by Archibald Menzies in 1791. Within the genus Adenanthos, it lies in the section Eurylaema and is most closely related to A. barbiger. A. obovatus has hybridized with A. detmoldii to produce the hybrid A. × pamela. Several common names allude to the prominent red flowers of the species. It grows as a many-stemmed spreading bush up to 1 m (3.3 ft) high, and about 1.5 m (4.9 ft) across, with fine bright green foliage. Made up of single red flowers, the inflorescences appear from April to December, and peak in spring.
