Robert Brown was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders.
Eucalyptus oleosa, commonly known as the red mallee, glossy-leaved red mallee, acorn mallee, oil mallee or giant mallee, is a tree or mallee that is native to Australia. The leaves were once harvested for the production of cineole based eucalyptus oil. Eucalyptus cneorifolia is now the predominant strain used in production due to a higher oil content in new growth.
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions. It is a characteristic that is not used scientifically for the definition of most families and genera of plants because it often can be used as an accurate characteristic only at the single species level. The word succulent comes from the Latin word sucus, meaning 'juice', or 'sap'. Succulent plants may store water in various structures, such as leaves and stems. The water content of some succulent organs can get up to 90–95%. Some definitions also include roots, thus geophytes that survive unfavorable periods by dying back to underground storage organs may be regarded as succulents. In horticultural use, the term succulent is sometimes used in a way that excludes plants that botanists would regard as succulents, such as cacti. Succulents are often grown as ornamental plants because of their striking and unusual appearance, as well as their ability to thrive with relatively minimal care.
The flora of Australia comprises a vast assemblage of plant species estimated to over 30,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae (Banksia), Myrtaceae, and Fabaceae.
Eucalyptus salmonophloia, commonly known as salmon gum, wurak or weerluk, is a species of small to medium-sized tree that is endemic to Western Australia. It has smooth bark, narrow lance-shaped to curved adult leaves, flower buds in groups of between nine and thirteen, creamy white flowers and hemispherical fruit.

Blanche Warre-Cornish née Ritchie was an English writer and conversationalist, celebrated for the "pregnant and startling irrelevancies" of her discourse. She edited some reminiscences of her cousin, the novelist William Thackeray.
Eucalyptus calycogona, commonly known as the gooseberry mallee or square fruited mallee, is a mallee that is endemic to southern Australia. It has smooth bark, narrow lance-shaped adult leaves, flower buds that are square in cross-section arranged in groups of seven in leaf axils, creamy white, sometimes pink flowers, and fruit that are square in cross-section.
Eucalyptus longicornis, commonly known as red morrel, morryl, poot or pu, is a species of large tree that is endemic to the south-west of Western Australia. It has rough, fibrous, fissured bark on the trunk, smooth greyish bark above, flower buds in groups of seven or more, white flowers and shortened spherical fruit.
Eucalyptus myriadena, also known as blackbutt, is a species of mallee or tree that is native to Western Australia. It has rough, coarse flaky bark on part of the trunk, smooth bark above, linear to narrow lance-shaped adult leaves, flower buds in groups of between nine and thirteen, white flowers and narrow cylindrical to barrel-shaped fruit. It is widely distributed in the wheatbelt and goldfield areas of the state.
