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.
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.
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.
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.
The Panax (ginseng) genus belongs to the "Araliaceae" (ivy) family.
 "Panax" species are characterized by the presence of ginsenosides and gintonin.
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".
Shiu-Ying Hu, BBS (22 February 1910 – 22 May 2012) was a Chinese botanist.
 She was an expert in the plant genera of "Ilex" (Aquifoliaceae), "Hemerocallis" (Amaryllidaceae), and "Panax" (Araliaceae).
 She studied the families Orchidaceae, Compositae, and Malvaceae, and Chinese medicinal herbs and food plants.
 She was given the nickname "Holly Hu" by her colleagues for her extensive work with holly plants.
Panax notoginseng is a species of the genus "Panax", and it is most commonly referred to in English as notoginseng.
 In Chinese it is called "tiánqī" (田七), tienchi ginseng, "sānqī" (三七) or "sanchi", three-seven root, and mountain plant.
 "P. notoginseng" belongs to the same scientific genus as Asian ginseng.
 In Latin, the word "panax" means "cure-all", and the family of ginseng plants is one of the best-known herbs.
Tabernaemontana is a genus of flowering plants in the family Apocynaceae.
 It has a pan-tropical distribution, found in Asia, Africa, Australia, North America, South America, and a wide assortment of oceanic islands.
 These plants are shrubs and small trees growing to 1–15 m tall.
 The leaves are evergreen, opposite, 3–25 cm long, with milky sap; hence it is one of the diverse plant genera commonly called "milkwood".
 The flowers are fragrant, white, 1–5 cm in diameter.
Carpentaria acuminata (carpentaria palm), the sole species in the genus Carpentaria, is a palm native to tropical coastal regions in the north of Northern Territory, Australia.

Question: are Carpentaria and Panax both plant genera ?
Answer: yes
