Acis trichophylla is a species of flowering plant in the family Amaryllidaceae, native to Portugal, Spain and Morocco. [1] 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 trichophylla is a bulbous perennial, growing up to 30 cm tall, although usually shorter. There are generally three very narrow leaves per bulb, appearing before the flowers, each leaf being up to 18 cm long but only at most 1 mm wide. Flowering is in late winter or early spring. The flowers are white, sometimes with pink tinges or occasionally all pink, and are arranged in groups of two to four on a stem (scape) that is about as long as or longer than the leaves. Each flower is borne on a long stalk (pedicel), up to 45 or 60 mm long, and has six tepals, 12–20 mm long, with sharp tips, that open widely to form a bell shape. The two spathes are shorter than the pedicels. The style is slightly longer than the stamens. [2] [3] [4] [5]
The nomenclature of Acis trichophylla is somewhat complex. The epithet trichophyllum was first published, in the combination Leucojum trichophyllum, by Peter Schousboe in 1800. [6] [7] The combination was used again as a supposedly new name by Félix Brotero in 1804, [8] but as it had already been published in 1800, Leucojum trichophyllumBrot. is an illegitimate later homonym. [1] In 1829, Robert Sweet suggested that Leucojum trichophyllum belonged in Acis, but did not explicitly use the combination Acis trichophylla nor make clear whose Leucojum name he meant. [9] The combination Acis trichophylla was first used in 1830 by George Don, referring to Sweet (he actually used the masculine form trichophyllus). [10]
Although William Herbert in 1837 also placed the species in Acis, [11] most later botanists used the genus Leucojum , treating it as L. trichophyllumSchousb. [2] [3] [4] In 2004, it was restored to Acis, along with other species of Leucojum, on the basis of a molecular phylogenetic study. [12]
A number of infraspecies have been described, none of which are recognized by the World Checklist of Selected Plant Families as of December 2017 [update] . [1] Forms with pinkish flowers have been called f. broteri and f. purpurascens, those with larger flowers var. grandiflorum. [3]
Acis trichophylla is found in central and southern Portugal, south central and south-western Spain and across the Mediterranean in Morocco. [1] It is found in dry sandy ground. [2]
Acis trichophylla is cultivated as an ornamental bulb. It requires protection from frost, and warm dry conditions for a long time in summer, hence growing in an alpine house or bulb frame is recommended. Unless planted deeply, around 15 cm, it tends to divide into small non-flowering bulbs. [3]
Amaryllis is the only genus in the subtribe Amaryllidinae. It is a small genus of flowering bulbs, with two species. The better known of the two, Amaryllis belladonna, is a native of the Western Cape region of South Africa, particularly the rocky southwest area between the Olifants River Valley and Knysna. For many years there was confusion among botanists over the generic names Amaryllis and Hippeastrum, one result of which is that the common name "amaryllis" is mainly used for cultivars of the genus Hippeastrum, widely sold in the winter months for their ability to bloom indoors. Plants of the genus Amaryllis are known as belladonna lily, Jersey lily, naked lady, amarillo, Easter lily in Southern Australia or, in South Africa, March lily due to its propensity to flower around March. This is one of numerous genera with the common name "lily" due to their flower shape and growth habit. However, they are only distantly related to the true lily, Lilium. In the Victorian Language of Flowers, amaryllis means "pride, determination and radiant beauty".
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.
Brunsvigia is a genus of African flowering plants in the family Amaryllidaceae, subfamily Amaryllidoideae. It contains about 20 species native to southeastern and southern Africa from Tanzania to Cape Province.
Melaleuca trichophylla is a shrub in the myrtle family, Myrtaceae, endemic to the south-west of Western Australia. Its pink or purple flowers appear from August to December in its native range. It has long been cultivated.
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.
Allium stocksianum is a species of flowering plant in the Amaryllidaceae family. It is native to Pakistan, Afghanistan and Iran. It is a perennial herb up to 15 cm tall, with a bulb up to 20 mm across. Umbels are hemispherical, up to 5 cm across, with pink to purple flowers.
Allium umbilicatum is a species of flowering plant in the Amaryllidaceae family. It is a wild onion native to Pakistan, Afghanistan, Turkmenistan, Uzbekistan, Iran, and Tajikistan. It is a perennial herb up to 40 cm tall, with an egg-shaped bulb up to 15 mm long. Leaves are tubular. Umbels are hemispherical, densely crowded with many pink flowers.
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.
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 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.
Nerine undulata syn. N. crispa is a species of flowering plant in the subfamily Amaryllidoideae of the family Amaryllidaceae, that is native to the eastern Cape of South Africa. Growing to 45 cm (18 in) tall, it is a bulbous perennial with narrow grasslike leaves that are almost evergreen, and umbels of 8-12 slender, crinkled pale pink or mid-pink flowers 5 cm across in autumn.
Nerine humilis, commonly known as dwarf nerine, is a species of flowering plant in the subfamily Amaryllidoideae of the family Amaryllidaceae, native to the Cape of South Africa. Growing to 40 cm (16 in) tall, it is a variable (polymorphic) bulbous perennial with narrow leaves appearing at the same time as umbels of 1-12 slender, crenellated flowers in shades of pink, in autumn. It is a summer dormant deciduous species, meaning that the top growth disappears for a period during summer months. Plants can be found in large colonies in their native habitat, the Fynbos of the Cape Floristic Region, appearing to respond well to the frequent fires in the area.
