Australian Cultivar Registration Authority: The Australian Cultivar Registration Authority (ACRA) is the International Cultivar Registration Authority (ICRA) for Australian plant genera, excluding those genera or groups for which other ICRAs have been appointed.

Nerine: Nerine (nerines, Guernsey lily, Jersey lily, spider lily) is a genus of flowering plants belonging to the Amaryllidaceae family, subfamily Amaryllidoideae.  They are bulbous perennials, some evergreen, associated with rocky and arid habitats.  They bear spherical umbels of lily-like flowers in shades from white through pink to crimson.  In the case of deciduous species, the flowers may appear on naked stems before the leaves develop.  Native to South Africa, there are about 20–30 species in the genus.  Though described as lilies, they are not significantly related to the true lilies (Liliaceae), but more closely resemble their relatives, "Amaryllis" and "Lycoris".  The genus was established by the Revd.  William Herbert in 1820.

Scirpus: Scirpus is a genus of aquatic, grass-like species in the family Cyperaceae (the sedges), many with the common names club-rush or bulrush (see also bulrush for other plant genera so-named).  Other common names are deergrass or grassweed.  They have grass-like leaves, and clusters of small spikelets, often brown.  Some species (e.g. "S. lacustris") can reach a height of 3 m, while others (e.g. "S. supinus") are much smaller, only reaching 20–30 cm tall.

Nerine latent virus: Nerine latent virus (NeLV) is a plant pathogenic virus.  It infects "Nerine", "Narcissus", "Hippeastrum" and "Ismene" plants.

Aichryson: Aichryson is a genus of about 15 species of succulent, subtropical plants, mostly native to the Canary Islands, with a few in the Azores, Madeira and Morocco, and one in Portugal.

Carduus: Carduus is a genus of flowering plants in the aster family, Asteraceae, and the tribe Cynareae, one of two genera considered to be true thistles, the other being "Cirsium".  Plants of the genus are known commonly as plumeless thistles.  They are native to Eurasia and Africa, and several are known elsewhere as introduced species.  This genus is noted for its disproportionately high number of noxious weeds compared to other flowering plant genera.

Robert Brown (botanist, born 1773): Robert Brown FRSE FRS FLS MWS (21 December 1773 – 10 June 1858) was a Scottish botanist and palaeobotanist 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, including the erection of 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.

Nerine sarniensis: Nerine sarniensis, commonly known as Guernsey lily or Jersey lily, is a species of flowering plant in the family Amaryllidaceae.  It is the type species of the "Nerine" genus.  It is widely cultivated in the temperate world and is particularly associated with the island of Guernsey, as reflected in both its Latin and common names ("sarniensis" means "from Guernsey"), though it doesn't originate there, nor is it a true lily (it is more closely related to "Amaryllis" and "Sternbergia").  It is native to the Northern and Western Cape Provinces of South Africa, though it is now naturalized in France, Madeira and Azores.

Isaac Henry Burkill: Isaac Henry Burkill (18 May 1870 – 8 March 1965) was an English botanist who worked in India and in the Straits Settlements (present day Singapore).  He worked primarily in economic botany but published extensively on plant biology, ethno-botany, insect-plant interactions and described several species.  He published a two volume compilation on the plants of economic importance in the Malay Peninsula, collating local names and knowledge.  He also wrote a detailed history of botany in India.  The plant genera "Burkillia" and "Burkillianthus" were named in his honour.

Matthew Jebb: Matthew Hilary Peter Jebb (born 1958) is an Irish botanist and taxonomist specialising in the ant plant genera "Squamellaria", "Myrmecodia", "Hydnophytum", "Myrmephytum" and "Anthorrhiza", as well as the carnivorous plant genus "Nepenthes".
