In botany, a bulb is structurally a short stem with fleshy leaves or leaf bases that function as food storage organs during dormancy.
 (In gardening, plants with other kinds of storage organ are also called "ornamental bulbous plants" or just "bulbs".)
Dovyalis is a genus of shrubs and small trees. Recent genetic evidence has shown the genus to belong to the family Salicaceae; formerly it was classified in the family Flacourtiaceae.
 The 15 species are native to Africa (Ethiopia south to South Africa) and southern Asia (India, Sri Lanka).
 Some are cultivated for their fruit.
Notholirion macrophyllum is a species of the genus "Notholorion", in the Liliaceae (lily) family.
 They are bulbous flowering plants originating in Asia.
 "N. macrophyllum" is the smallest species in the family, with a height of 20–25 cm.
 The leaves are basal, 30–40 cm long and about 2 cm wide.
 from June to August "N. macrophyllum" produces a racemose inflorescence bearing 2–4 (occasionally 6) pale violet to purple or red, bell-shaped, hermaphrodite, flowers with dark purple flecks in the throat, about 5 cm in length.
 After flowering the plant produces a capsular fruit.
The following is a list of tulip species and cultivars which have gained the Royal Horticultural Society's Award of Garden Merit.
 They are bulbous perennials, originally from sunny, open habitats in Europe and Asia.
 Thousands of cultivars are available in a huge range of sizes, shapes and colours (other than pure blue).
 They are usually sold as bulbs to be planted in autumn and winter for flowering in mid- to late spring.
 They are frequently treated as bedding plants, accompanied by other seasonal favourites such as wallflowers and forget-me-nots, flowering for one season before being discarded.
 However, in favoured locations they can be left in the ground to re-appear the following and subsequent years.
 Like many other bulbous plants they require a hot, dry dormant period in the summer.
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.
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.
Calydorea is a small genus of perennial, herbaceous and bulbous plants in the iris family (Iridaceae) native to Mexico and South America.
 The plants in the genus are small with tunicated bulbs.
 The flowers are light blue, violet, white, or yellow, depending on the species, of which there are around twenty.
 Taxonomists considered that the already known genera "Salpingostylis" (endemic from Florida), "Cardiostigma" (from Mexico), "Catila" (from Brazil) and "Itysa" (from Venezuela) are not enough different from each other to justify their taxonomic segregation and, for this reason, all of them are now included in "Calydorea".
Brian Frederick Mathew MBE, VMH is a British botanist, born in the village of Limpsfield, Surrey, England.
 His particular area of expertise is bulbous plants, particularly ornamental bulbous plants, although he has contributed to other fields of taxonomy and horticulture.
 He has authored or co-authored many books on bulbs and bulbous genera which appeal to both botanists and gardeners, as well as specialist monographs on other genera, including "Daphne" (with Chris Brickell), "Lewisia", and "Helleborus".
 His work has been recognized by the British Royal Horticultural Society and the International Bulb Society.
Tocantinia is a monotypic genus of herbaceous perennial bulbous plants flowering plants in the Amaryllis (Amaryllidaceae) family, subfamily Amaryllidoideae.
 The sole species is Tocantinia mira.
Notholirion is a small Asian genus of bulbous plants in the lily family.
 It is closely related to Lilium, but each individual flowers only once, and then dies after producing offsets.
 The bulb is covered by a tunic.
 Leaves are basal, produced in autumn and winter.

Question: Are both Dovyalis and Notholirion bulbous plants?
