Pseudoprospero firmifolium | |
Pseudoprospero is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae (also treated as the family Hyacinthaceae). [2] The genus has a single species Pseudoprospero firmifolium, [1] which is endemic to South Africa (the Cape Province, KwaZulu-Natal). [3]
Pseudoprospero firmifolium grows from an underground bulb whose tunic has dry, paper-like outer layers. The channelled linear leaves are evergreen. The flowers are borne in a loose many-flowered raceme, which usually has a side branch. Individual flowers have white to lilac tepals which are joined at the base and persist into the fruiting stage. The stamens are more-or-less erect, with filaments joined at the base to the tepals and to each other. The seeds are black. [4]
From the 1970s onwards, Franz Speta and co-workers split up the broadly defined genus Scilla , placing many of its species into separate genera. [5] One of these genera was Pseudoprospero, created by Speta in 1998 for the former Scilla firmifolia. [1] Subsequent studies have confirmed that Pseudoprospero firmifolium is distinct not only from Scilla but from all other genera in the tribe Hyacintheae (or the subfamily Hyacinthoideae for those who accept the family Hyacinthaceae), [6] being placed in its own subtribe. [note 1]
Two subspecies are recognised: [1]
Five homoisoflavanones, 3,5-dihydroxy-7,8-dimethoxy-3-(3',4'-dimethoxybenzyl)-4-chromanone, 3,5-dihydroxy-7-methoxy-3-(3',4'-dimethoxybenzyl)-4-chromanone, 3,5-dihydroxy-7,8-dimethoxy-3-(3'-hydroxy-4'-methoxybenzyl)-4-chromanone, 3,5,6-trihydroxy-7-methoxy-3-(3'-hydroxy-4'-methoxybenzyl)-4-chromanone and 3,5,7-trihydroxy-3-(3'-hydroxy-4'methoxybenzyl)-4-chromanone, can be isolated from the dichloromethane extract of the bulbs of P. firmifolium.

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. 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.
Ledebouria is a genus of African bulbous perennial herbs in the Asparagus family, Asparagaceae, subfamily Scilloideae. Most members were previously part of the genus Scilla. A number of species are grown by cacti and succulent enthusiasts for their patterned leaves.
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.
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.
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.
Scilla litardierei, the amethyst meadow squill or Dalmatian scilla, is a species of flowering plant in the family Asparagaceae. A bulbous perennial, with blue grape-hyacinth like flowers, blooming in late spring, much later than the more popular Siberian squill and later than Muscari which it resembles.
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.
Daubenya is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae. It is native to the Cape Province of South Africa. At first believed to consist of a single species, Daubenya aurea, the genus was expanded in 2000 to include the genera Androsiphonand Amphisiphon and various species that had previously been classified as Polyxena, Massonia, or Neobakeria. "The poor congruence between morphological and other characters within Hyacinthaceae has also made generic circumscriptions very difficult. One of the consequences of this has been the recognition of a large number of genera that are poorly defined morphologically."-
Fessia is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae. It is distributed from Iran to Central Asia and Pakistan.
Fusifilum is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae. It is distributed in southern Africa. Some sources consider that all the species should be placed in the genus Drimia.
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.
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.
Homoisoflavonoids (3-benzylidenechroman-4-ones) are a type of phenolic compounds occurring naturally in plants.
Eucomis montana is a plant species in the family Asparagaceae, subfamily Scilloideae, found in South Africa and Eswatini (Swaziland). When in flower in summer, the plant reaches a height of up to 45 cm, with a dense spike (raceme) of greenish flowers, topped by a "head" of green bracts.
