Question: Are Muscari and Cananga both genuses?
Context: Cananga is a small genus of trees in the family Annonaceae.  One of its species, "Cananga odorata", is important as the source of the perfume ylang-ylang.  Two species are recognized: Muscari botryoides is a bulbous perennial plant of the genus "Muscari" and one of a number of species and genera known as grape hyacinth.  It is sometimes grown as an ornamental plant. Muscari armeniacum is a bulbous plant of the genus "Muscari" with basal, simple leaves and short, flowering stems.  It is one of a number of species and genera known as grape hyacinth, in this case Armenian grape hyacinth or Garden Grape-hyacinth.  The flowers are purple, blue (with a white fringe), white (var.  "Album") or pale pink (var "Pink Sunrise") and the plants are usually 15 cm tall.  "M. armeniacum" blooms in mid-Spring (April or May in the Northern Hemisphere) for 3–4 weeks.  Some selections are fragrant.  Established bulbs leaf in the autumn. Muscari neglectum is a perennial bulbous plant, one of a number of species and genera known as grape hyacinth and in particular common grape hyacinth or starch grape hyacinth. " Muscari" are perennial bulbous plants native to Eurasia.  They produce spikes of dense, commonly blue, urn-shaped flowers.  It is sometimes grown as an ornamental plant, for example, in temperate climates as a spring bulb. Pseudomuscari is a genus of bulbous perennials in the family Asparagaceae, subfamily Scilloideae.  They were formerly included in the genus "Muscari" (as the Pseudomuscari group, section or subgenus).  Species of "Pseudomuscari" have flowers in shades of pale or bright blue, and are small plants with dense flower spikes or racemes.  A feature which distinguishes them from "Muscari" is the bell-shaped flower which is not constricted at the mouth.  One species, "P. azureum", is popularly grown in gardens as an ornamental Spring-flowering plant. Muscari latifolium (broad-leaved grape hyacinth) is a species of flowering plant of the genus of the grape hyacinths ("Muscari") in the family (Asparagaceae).  The specific epithet "latifolium" means "broad-leaved". Muscari racemosum is a perennial bulbous plant, one of a number of species and genera known as grape hyacinth.  Originally from south-west Turkey where it grows in rocky places, it is sometimes grown as an ornamental plant.  It may be found in the horticultural literature under the synonym "Muscari muscarimi". Cananga odorata, known as the cananga tree (Indonesian: "kenanga" , Filipino: "ilang-ilang" ), is a tropical tree that originates in Indonesia, which in early 19th century spread to Malaysia and the Philippines.  It is valued for the perfume extracted from its flowers, called ylang-ylang (a name also sometimes used for the tree itself), which is an essential oil used in aromatherapy.  The tree is also called the fragrant cananga, Macassar-oil plant, or perfume tree.  Traditional Polynesian names include Mata‘oi (Cook Islands), Mohokoi (Tonga), Moso‘oi (Samoa), Moto‘oi (Hawai), Mokosoi/Mokasoi/Mokohoi (Fiji). 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". Muscari is a genus of perennial bulbous plants native to Eurasia that produce spikes of dense, most commonly blue, urn-shaped flowers resembling bunches of grapes in the spring.  The common name for the genus is grape hyacinth (a name which is also used for the related genera "Leopoldia" and "Pseudomuscari", which were formerly included in "Muscari"), but they should not be confused with hyacinths.  A number of species of "Muscari" are used as ornamental garden plants.
