Question: Are Hyacinthoides and Brahea both plant genera ?
Context: 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. The name Felicia derives from the Latin adjective "felix", meaning "happy", though in the neuter plural form "felicia" it literally means "happy things" and often occurred in the phrase "tempora felicia", "happy times".  The sense of it as a feminine personal name appeared in post-Classical use and is of uncertain origin.  It is associated with saints, poets, astronomical objects, plant genera, fictional characters, and animals, especially cats. 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. Hyacinthoides is a genus of flowering plants in the family Asparagaceae, known as bluebells. 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". 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. Hyacinthoides lingulata is a species of bulbous plant that lives in North Africa, from Morocco to Tunisia.  It is widespread in short grass and agricultural fields, flowering in autumn when the rains begin.  The flowers are generally paler than the common bluebell ("Hyacinthoides non-scripta"), but have a similar scent. Brahea is a genus of palms in the Arecaceae family.  They are commonly referred to as Hesper Palms and are endemic to Mexico and Central America.  All Hesper Palms have large, fan-shaped leaves. 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.
