Phebalium glandulosum
Phebalium glandulosum, commonly known as desert phebalium, is a species of shrub that is endemic to eastern Australia. It has glandular-warty stems covered with silvery to rust-coloured scales, wedge-shaped leaves that are scaly on the lower surface, and yellow flowers arranged in umbels on the ends of branchlets. Description. "Phebalium glandulosum" is a shrub that typically grows to a height of . It has glandular-warty stems that are densely covered with silvery to rust-coloured scales. It has wedge-shaped leaves that are long and wide on a short petiole. Five to ten pale to  bright yellow flowers are arranged in more or less sessile umbels on the ends of branchlets, each flower on a pedicel long. The calyx is hemispherical to top-shaped, long, glandular warty and covered with scales on the outside. The petals are long and overlap each other. Flowering occurs in spring and the follicles are erect and long. Taxonomy. The species was first formally described by English botanist William Jackson Hooker in Thomas Mitchell's "Journal of an Expedition into the Interior of Tropical Australia" in 1848. In 1970, Peter G. Wilson described three subspecies of "P. glandulosum" in the  journal "Nuytsia", a further subspecies in 1998 in the same journal and in 2008 Robyn L. Giles described a further three in "Australian Systematic Botany". The names of the six subspecies are accepted at the Australian Plant Census: Distribution and habitat. "Phebalium glandulosum" is widespread in heath, forest and mallee and occurs in Queensland, New South Wales, Victoria and South Australia.
