Merwilla plumbea, also known as the blue squill, is a threatened bulb-forming perennial herb in the small genus Merwilla endemic to the Drakensberg. [1] [2]
Merwilla plumbea is found in the eastern part of South Africa, in Eswatini and Lesotho. [2]
Merwilla plumbea is found on rocky, well-drained slopes at altitudes between 300-2500 metres. [2]
Mature individuals are thought to live, on average, for 25 years. [2]
Merwilla plumbea has been assessed as near threatened due to a 25% decline in the local population from intensive poaching of the bulbs in the wild. In 2006, 1 851 580 bulbs in the Warwick Muti Market and 235 872 bulbs were sold in the Faraday Muti Market. [2]
Two subspecies are recognised: [3]
Freesia is a genus of herbaceous perennial flowering plants in the family Iridaceae, first described as a genus in 1866 by Christian Friedrich Ecklon (1886) and named after the German botanist and medical practitioner, Friedrich Freese (1795-1876). It is native to the eastern side of southern Africa, from Kenya south to South Africa, most species being found in Cape Provinces. Species of the former genus Anomatheca are now included in Freesia. The plants commonly known as "freesias", with fragrant funnel-shaped flowers, are cultivated hybrids of a number of Freesia species. Some other species are also grown as ornamental plants.
Scilla luciliae is a species of flowering plant in the family Asparagaceae. It is referred to by the common names Bossier's glory-of-the-snow or Lucile's glory-of-the-snow, and is a bulbous perennial from western Turkey that flowers in early spring. After flowering, it goes into dormancy until the next spring. The specific epithet is in honour of Lucile, the wife of the Swiss botanist Pierre Edmond Boissier (1810-1885). It belongs to a group of Scilla species that were formerly put in a separate genus, Chionodoxa, and may now be treated as Scilla sect. Chionodoxa.
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.
Scilla section Chionodoxa, known as glory-of-the-snow, is a small group of bulbous perennial flowering plants in the family Asparagaceae, subfamily Scilloideae. Formerly treated as the separate genus Chionodoxa, they are now included in Scilla as a section. The section is endemic to the eastern Mediterranean, specifically Crete, Cyprus and Turkey. The blue, white or pink flowers appear early in the year making them valuable garden ornamentals. The common name of the group is based on the habit of flowering in high alpine zones when the snow melts in spring.
Scadoxus is a genus of African and Arabian plants in the Amaryllis family, subfamily Amaryllidoideae. The English names blood lily or blood flower are used for some of the species. The genus has close affinities with Haemanthus. Species of Scadoxus are grown as ornamental plants for their brilliantly coloured flowers, either in containers or in the ground in frost-free climates. Although some species have been used in traditional medicine, they contain poisonous alkaloids.
Cyrtanthus is a genus of perennial, herbaceous and bulbous plants in the family Amaryllidaceae, subfamily Amaryllidoideae.
Scilla nana, known as dwarf glory-of-the-snow, is a bulbous perennial flowering plant endemic to Crete. It flowers in early spring with flowers in shades of lilac blue. After flowering, it goes into dormancy until the next spring. It belongs to a group of Scilla species that were formerly put in a separate genus, Chionodoxa, and may now be treated as Scilla sect. Chionodoxa. It has not always been recognized as distinct from Scilla cretica.
Scilla lochiae, known as Loch's glory-of-the-snow, is a bulbous perennial from Cyprus flowering in early spring. After flowering, it goes into dormancy until the next spring. It was named after Lady Loch who collected it. It belongs to a group of Scilla species that were formerly put in a separate genus, Chionodoxa, which may now be treated as Scilla sect. Chionodoxa.
Scilla bifolia, the alpine squill or two-leaf squill, is a herbaceous perennial plant growing from an underground bulb, belonging to the genus Scilla of the family Asparagaceae.
Scilla × allenii is a hybrid between two species of flowering plants, both of which are now placed in the genus Scilla. One of the parents is Scilla bifolia. As of March 2020, sources differ as to the identity of the other, which may be either Scilla forbesii or Scilla luciliae.
Barnardia is a small genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae. The genus has two species, one found in the Balearic Islands and north-west Africa, the other in east China, Korea, Japan and adjacent localities. It was suggested in 2012 that the two species were not closely related.
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.
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.
Scadoxus membranaceus is a flowering plant in the Amaryllidaceae family. It is a bulbous plant from South Africa. The smallest of the species of Scadoxus, it is sometimes cultivated as an ornamental plant where a minimum temperature of 5 °C (41 °F) can be maintained.
Leucojum aestivum, commonly called summer snowflake or Loddon lily, is a plant species widely cultivated as an ornamental. It is native to most of Europe from Spain and Ireland to Ukraine, with the exception of Scandinavia, Russia, Belarus and the Baltic countries. It is also considered native to Turkey, Iran and the Caucasus. It is naturalized in Denmark, South Australia, New South Wales, Nova Scotia and much of the eastern United States.
Scilla cretica is a species of flowering plant in the Asparagaceae family. It is referred to by the common name Cretan glory-of-the-snow, and is a bulbous perennial native to Crete, flowering in early spring. It belongs to a group of Scilla species that were formerly put in a separate genus, Chionodoxa, and may now be treated as Scilla sect. Chionodoxa. It has not always been recognized as distinct from Scilla nana.
Galanthus plicatus, the pleated snowdrop, is a species of flowering plant in the family Amaryllidaceae, native to eastern Europe and western Asia. It is a spring flowering bulbous herbaceous perennial.
Anacampseros papyracea is a species of succulent plant in the family Anacampserotaceae. It is endemic to Southern Africa.
