Pseudogaltonia is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae (also treated as the family Hyacinthaceae). [3] It is distributed in southern Africa (the Cape Province of South Africa, Namibia, Botswana). [2]
Pseudogaltonia grows from a large bulb with a fibrous tunic. The flowers are borne on a long stem (scape) in a pyramid-shaped raceme. Individual flowers are borne on long stalks (pedicels) and droop downwards. The tepals are fused at the base, forming a tube about two-thirds or three-quarters of the length of the flower, swollen slightly at its base. The tubular part of the tepals is green, the free lobes are whitish with a green streak. The stamens, which protrude from the flower, have broad triangle-shaped filaments which arise from the mouth of the flower tube and green anthers. The seeds are black. [4] [5]
The name Pseudogaltonia was first used by Otto Kuntze in 1886 as the name of a section within the genus Hyacinthus . He also suggested that those who preferred smaller genera could use it as the name of a separate genus. [6] [note 1] In 1888, Adolf Engler used Kuntze's Pseudogaltonia as a genus name in his treatment of the Liliaceae. [8] Kuntze had named the only species known at that time as Hyacinthus pechuelii, which Engler transferred to Pseudogaltonia pechuelii. However, the species had already been described with the name Galtonia clavata in 1884, giving the epithet "clavata" priority over "pechuelii." [9] A second species of Pseudogaltonia, P. liliiflora, was named in 2009. [10]
The genus is placed in the tribe Ornithogaleae (or the subfamily Ornithogaloideae by those who use the family Hyacinthaceae). Within this tribe, molecular phylogenetic studies place it as most closely related to the genus Dipcadi . [4]
As of April 2013 [update] , the World Checklist of Selected Plant Families recognized the following two species: [10]
Hyacinthus is a small genus of bulbous herbs, spring-blooming perennials. They are fragrant flowering plants in the family Asparagaceae, subfamily Scilloideae and are commonly called hyacinths. The genus is native predominantly to the Eastern Mediterranean region from the south of Turkey to the Palestine region, although naturalized more widely.
Scilla is a genus of about 30 to 80 species of bulb-forming perennial herbaceous plants in the family Asparagaceae, subfamily Scilloideae. Sometimes called the squills in English, they are native to woodlands, subalpine meadows, and seashores throughout Europe, Africa and the Middle East. A few species are also naturalized in Australasia and North America. Their flowers are usually blue, but white, pink, and purple types are known; most flower in early spring, but a few are autumn-flowering. Several Scilla species are valued as ornamental garden plants.
Scilloideae is a subfamily of bulbous plants within the family Asparagaceae. Scilloideae is sometimes treated as a separate family Hyacinthaceae, named after the genus Hyacinthus. Scilloideae or Hyacinthaceae include many familiar garden plants such as Hyacinthus (hyacinths), Hyacinthoides (bluebells), Muscari and Scilla and Puschkinia. Some are important as cut flowers.
Ornithogalum is a genus of perennial plants mostly native to southern Europe and southern Africa belonging to the family Asparagaceae. Some species are native to other areas such as the Caucasus. Some species are classified as noxious invasive weeds in some portions of North America. Growing from a bulb, species have linear basal leaves and a slender stalk, up to 30 cm tall, bearing clusters of typically white star-shaped flowers, often striped with green. The common name of the genus, star-of-Bethlehem, is based on its star-shaped flowers, after the Star of Bethlehem that appears in the biblical account of the birth of Jesus. The number of species has varied considerably, depending on authority, from 50 to 300.
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, but they should not be confused with hyacinths. A number of species of Muscari are used as ornamental garden plants.
Galtonia is a genus of plants in the family Asparagaceae, subfamily Scilloideae. Native to Southern Africa, the genus is named after Sir Francis Galton. According to some authorities it has been subsumed into Ornithogalum as a subgenus, while others prefer to keep it as a separate genus.
Massonia is a genus of bulbous perennial flowering plants in the family Asparagaceae, subfamily Scilloideae. It is native to southern Africa, and is found in localities such as Namaqualand with hot and dry summers, being dormant in summer and growing during winter. The genus Whiteheadia has been merged into Massonia. It is classed as a cryptophyte.
Puschkinia is a genus of four known species of bulbous perennials in the family Asparagaceae, subfamily Scilloideae. It is native to the Caucasus and the Middle East. Puschkinia scilloides is grown as an ornamental bulbous plant.
Lachenalia is a genus of bulbous perennial plants in the family Asparagaceae, subfamily Scilloideae, which are usually found in Namibia and South Africa. Most of them have a dormancy period, but new roots will always grow every year.
Drimia is a genus of African, south European and south Asian flowering plants. In the APG IV classification system, it is placed in the family Asparagaceae, subfamily Scilloideae. When broadly circumscribed, the genus includes a number of other genera previously treated separately, including Litanthus, Rhodocodon, Schizobasis and Urginea.
Oziroe is a genus of bulbous South American plants in the squill subfamily within the asparagus family. Within the Scilloideae, it is the sole member of the tribe Oziroëeae and the only genus in the subfamily to be found in the New World.
Alrawia is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae. It is native to north-eastern Iraq and Iran.
Daubenya is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae. It is native to the Cape Province of South Africa.
Dipcadi is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae. It is widely distributed, occurring in southern Europe, most of Africa and the Middle East through to the Indian subcontinent.
Fessia is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae. It is distributed from Iran to Central Asia and Pakistan.
Merwilla is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae. It is distributed in southern Africa, from Zimbabwe to South Africa. This genus is named after the botanist Frederick Ziervogel Van der Merwe (1894–1968), who worked on this group.
Namophila is a monotypic genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae. The sole species Namophila urotepala is endemic to Namibia.
Prospero is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae. It is distributed in Europe, around the Mediterranean, and through the Middle East to the Caucasus.
Pseudoprospero is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae. The genus has a single species Pseudoprospero firmifolium, which is endemic to South Africa.
Spetaea is a monotypic genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae. The only known species Spetaea lachenaliiflora is found only in the south-west of the Cape Province in South Africa. Prior to 2003, it was incorrectly known as Scilla plumbea.
