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.
Bellevalia is a genus of plants in the family Asparagaceae, subfamily Scilloideae.
 It was first described as a genus in 1808.
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.
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.
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.
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.
Comptonella is a plant genus endemic to New Caledonia in the subfamily Rutoideae in the family Rutaceae.
 Molecular phylogenetic analyses suggest that this genus is nested in "Melicope".
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".
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.
Bellevalia paradoxa is a bulb forming plant in the genus "Bellevalia" of the "Asparagaceae" family, formerly classified in the "Muscari" genus, under which name it is commonly sold as "Muscari paradoxum".

Question: Are the plant genera Comptonella and Bellevalia in the same family?
Answer: no
