Dipcadi is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae (also treated as the family Hyacinthaceae). [2] It is widely distributed, occurring in southern Europe, most of Africa and the Middle East through to the Indian subcontinent. [1]

Description

Species of Dipcadi grow from small bulbs. The solitary flower stem (scape) bears a loose raceme of green or brown flowers, sometimes with different colours at the tips of the three inner tepals. The raceme is usually one-sided (secund). The tepals are joined at the base for up to two thirds of their length to form a tube. The apices of the tepals then curve outwards, particularly the outer three. The outer three tepals may have a rounded "spur" at their tips. The stamens, which are enclosed within the flower, are joined to the tube formed by the tepals and have flat filaments. The black seeds are in the shape of a disc or a flattened globe. [3] [4]

Dipcadi serotinum, from south-west Europe and north Africa, although sombre in colour, is sometimes cultivated by gardeners specializing in ornamental bulbous plants. [5]

Systematics

The genus was named by Friedrich Kasimir Medikus in 1790, based on the species Linnaeus had called Hyacinthus serotinus. Medikus distinguished Dipcadi from Hyacinthus because of the former's many flattened seeds and tubular flowers. [6] Along with three other genera, Albuca , Ornithogalum sensu lato and Pseudogaltonia , Dipcadi is placed in the tribe Ornithogaleae (or subfamily Ornithogaloideae by those who recognize the Scilloideae as the separate family Hyacinthaceae). [7]

Species

As of March 2013, the World Checklist of Selected Plant Families recognized 41 species and one hybrid: [8]

<span class="mw-page-title-main">Hyacinth</span> Genus of flowering plants in the family Asparagaceae

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.

<span class="mw-page-title-main">Scilloideae</span> Subfamily of bulbous monocot 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.

<i>Ornithogalum</i> Genus of perennial bulbous plants in the asparagus family (Asparagaceae

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.

<i>Muscari</i> Genus of flowering plants in the family Asparagaceae

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.

<i>Galtonia</i> Genus of 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.

<i>Massonia</i> Genus of flowering plants

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.

<i>Puschkinia</i> Genus of flowering plants

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.

<i>Scilla nana</i> Species of flowering plant

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.

<i>Drimia</i> Genus of flowering plants

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.

Alrawia is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae. It is native to north-eastern Iraq and Iran.

<i>Barnardia</i> Genus of flowering plants

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.

<i>Daubenya</i> Genus of flowering plants

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."-

<i>Fessia</i> Genus of flowering plants

Fessia is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae. It is distributed from Iran to Central Asia and Pakistan.

<i>Merwilla</i> Genus of flowering plants

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.

<i>Spetaea</i> Genus of flowering plants

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.

<i>Albuca shawii</i> Species of flowering plant

Albuca shawii is a species of bulbous plant from southern Africa. It flowers in the summer and has yellow flowers on stems to about 30 cm high.

<i>Eucomis humilis</i> Species of flowering plant

Eucomis humilis is a species of flowering plant in the family Asparagaceae, subfamily Scilloideae, native to KwaZulu-Natal and Lesotho. It was first described by Baker in 1895. The greenish to purplish flowers appear in summer and are arranged in a spike (raceme), topped by a "head" of green leaflike bracts. Cultivated as an ornamental plant, it can be grown successfully outside where frosts are not too severe.
