Galanthus is a small genus of approximately 20 species of bulbous perennial herbaceous plants in the family Amaryllidaceae. The plants have two linear leaves and a single small white drooping bell shaped flower with six petal-like (petaloid) tepals in two circles (whorls). The smaller inner petals have green markings.
Leucojum is a small genus of bulbous plants native to Eurasia belonging to the Amaryllis family, subfamily Amaryllidoideae. As currently circumscribed, the genus includes only two known species, most former species having been moved into the genus Acis. Both genera are known as snowflakes.
Galanthus nivalis, the snowdrop or common snowdrop, is the best-known and most widespread of the 20 species in its genus, Galanthus. Snowdrops are among the first bulbs to bloom in spring and can form impressive carpets of white in areas where they are native or have been naturalised. They should not be confused with the snowflakes, in the genera Leucojum and Acis.
Allium calamarophilon is a species of plant in the genus Allium. It is endemic to Greece, known only from one small population on the Island of Euboea, on a rocky ledge in the center of the island near the town of Kimi. Its natural habitats are Mediterranean-type shrubby vegetation and rocky shores. It is threatened by habitat loss.
Acis is a genus of perennial, herbaceous and bulbous plants in the amaryllis family. The genus consists of nine species distributed in Europe and Northern Africa. Acis was previously included in Leucojum; both genera are known as snowflakes.
Persoonia isophylla is a plant in the family Proteaceae and is endemic to New South Wales. It is an erect or spreading shrub with soft, pine-like leaves and groups of cylindrical yellow flowers. It is similar to P. pinifolia but the flowers of that species have small leaves at their base, where the flowers of P. isophylla have full-sized leaves at their base. The two species sometimes grow together but hybrids between them are rare.
Allium tenuiflorum is a Mediterranean species of wild onion found in Algeria, Morocco, Libya, Italy including Sardinia, and the Balkans.
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 Republics. 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.
Leucojum vernum, called spring snowflake, is a perennial bulbous flowering plant species in the family Amaryllidaceae that includes the onions, daffodils and Agapanthus. It is native to central and southern Europe from Belgium to Ukraine. It is considered naturalized in north-western Europe, including Great Britain and parts of Scandinavia, and in the US states of Georgia and Florida. It is cultivated as a spring-flowering ornamental bulbous plant. Usually a single white flower with greenish marks near the tip of each tepal is borne on a stem about 10–20 cm tall, occasionally more.
Fritillaria messanensis is a European species of flowering plant in the lily family, native to southeastern Europe: Italy, Greece, Albania, former Yugoslavia.
Acis autumnalis, the autumn snowflake, is a species of flowering plant in the family Amaryllidaceae. A short bulbous perennial, it is found on the western shores of the Mediterranean, from Spain and Morocco to Sicily and Tunisia.
Acis fabrei is a bulbous flowering plant in the family Amaryllidaceae, native to France. It has white flowers that appear in late spring after the leaves. Although first collected in 1882, it was not scientifically described until 1990. It is now known from only four populations in the Vaucluse department in south-east France, around Mont Ventoux and the River Nesque. It is considered to be a "threatened species".
Acis longifolia is a species of flowering plant in the family Amaryllidaceae, endemic to Corsica. Its white flowers appear in spring. It is sometimes cultivated as an ornamental plant, but is not fully frost-hardy.
Acis nicaeensis, sometimes called the French snowflake, is a species of flowering plant in the family Amaryllidaceae, native to south-eastern France. A small spring flowering bulb with white flowers, it is cultivated as an ornamental plant.
Acis tingitana is a species of flowering plant in the family Amaryllidaceae, native to north Morocco. Rare in cultivation, it is not fully frost-hardy.
Acis trichophylla is a species of flowering plant in the family Amaryllidaceae, native to Portugal, Spain and Morocco. It has very narrow leaves. The flowers are produced in late winter or early spring and are usually white, but sometimes pink-tinged or all pink. The species is cultivated as an ornamental bulb, but requires protection from hard frost.
Acis valentina is a species of bulbous flowering plant in the family Amaryllidaceae, native to eastern Spain. Its white flowers appear in autumn. It can be grown as an ornamental bulb, but may need protection from hard frost.
Acis rosea, known as the rose snowflake, is a species of flowering plant in the family Amaryllidaceae, native to Corsica and Sardinia. Unlike most members of the genus Acis, it has pink rather than white flowers. It is grown as an ornamental plant but requires protection from frost.
Galanthus reginae-olgae is a species of flowering plant in the family Amaryllidaceae, native to Sicily and the west and north-west Balkans. Some variants produce their pendant white flowers in autumn, others in winter and early spring. It is cultivated as ornamental bulbous plant, preferring warmer situations in the garden than other species of Galanthus (snowdrops).
Stenomesson leucanthum is a species of flowering plant in the family Amaryllidaceae. It is native to Peru. Pierfelice Ravenna the Chilean botanists who first formally described the species, using the basionym Pucara leucantha, named it after its white flowers.
