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.
The tribe Griffineae includes 2 genera with 22 species from South America which are actually endemic to Brazil. A typical character of the representatives of the tribe are the flowers - They are with blue or lilac color collected into an umbel. Only the members of this tribe and the genus Lycoris are able to form flowers with such color in the whole family Amaryllidaceae. The plants in this group are typical perennial flowers which are producing bulbs. The leaves are green, with elliptical form in the most of the cases but in some members as in Worsleya they are sword-shaped.
The Amaryllidaceae are a family of herbaceous, mainly perennial and bulbous flowering plants in the monocot order Asparagales. The family takes its name from the genus Amaryllis and is commonly known as the amaryllis family. The leaves are usually linear, and the flowers are usually bisexual and symmetrical, arranged in umbels on the stem. The petals and sepals are undifferentiated as tepals, which may be fused at the base into a floral tube. Some also display a corona. Allyl sulfide compounds produce the characteristic odour of the onion subfamily (Allioideae).
Hippeastreae is a tribe of plants belonging to the subfamily Amaryllidoideae of the Amaryllis family (Amaryllidaceae). Species in this tribe are distributed in South America. Flowers are large and showy, zygomorphic, with the stamens in varying lengths, inflorescence bracts are often fused basally. The seeds are flattened, winged or D-shaped. Reported basic chromosome numbers are x= 8-13, 17, and higher. All the species in this tribe present a remarkable aesthetic interest and horticultural value.
Amaryllidoideae is a subfamily of monocot flowering plants in the family Amaryllidaceae, order Asparagales. The most recent APG classification, APG III, takes a broad view of the Amaryllidaceae, which then has three subfamilies, one of which is Amaryllidoideae, and the others are Allioideae and Agapanthoideae. The subfamily consists of about seventy genera, with over eight hundred species, and a worldwide distribution.
Narcisseae is a small tribe of plants belonging to the subfamily Amaryllidoideae of the Amaryllis family (Amaryllidaceae), where it forms part of the Eurasian clade, and is one of three tribes in the European (Mediterranean) clade. It contains two genera and approximately 58 species, but probably also Lapiedra. The two genera are distinguished from each other by the presence of a paraperigonium in the former.
Haemantheae are a tribe of subfamily Amaryllidoideae. They are herbaceous monocot perennial flowering plants with a predominantly African distribution. Three subtribes are proposed and six genera including the type genus, Haemanthus, are included. They are characterised by the presence of baccate (berry) fruit.
Calostemmateae are a very small tribe of subfamily Amaryllidoideae. They are herbaceous monocot perennial flowering plants endemic to Australasia. The tribe consists of two genera, Proiphys and Calostemma.
Pancratieae are a small European tribe of subfamily Amaryllidoideae, consisting of two genera including the type genus, Pancratium.
Traubiinae is a subtribe of plants classified under the tribe Hippeastreae. It belongs to the subfamily Amaryllidoideae of the Amaryllis family (Amaryllidaceae).
Eustephieae is a tribe, where it forms part of the Andean clade, one of two American clades.
Stenomesseae was a tribe, where it forms part of the Andean clade, one of two American clades. The tribe was originally described by Traub in his monograph on the Amaryllidaceae in 1963, as Stenomessae based on the type genus Stenomesson. In 1995 it was recognised that Eustephieae was a distinct group separate from the other Stenomesseae. Subsequently, the Müller-Doblies' (1996) divided tribe Eustephieae into two subtribes, Stenomessinae and Eustephiinae.
Eucharideae is a tribe of plants within the family Amaryllidaceae. It was augmented in 2000 by Meerow et al. following a molecular phylogenetic study that revealed that many elements of the tribe Stenomesseae segregated with it, rather than separately, and were subsequently submerged in it. It forms one of the tribes of the Andean subclade of the American clade of the subfamily.
Clinantheae is a tribe, where it forms part of the Andean clade, one of two American clades. The tribe was described in 2000 by Alan Meerow et al. as a result of a molecular phylogenetic study of the American Amaryllidoideae. This demonstrated that the tribe Stenomesseae, including the type genus Stenomesson was polyphyletic. Part of the tribe segregated with the Eucharideae and were submerged into it, while the other part formed a unique subclade. Since the type species of Stenomesson was not part of the second sublclade it was necessary to form a new name for the remaining species together with the other genera that remained. This was Clinanthus, the oldest name for these species, and consequently the tribe Clinantheae.
Hymenocallideae is a tribe, where it forms part of the Andean clade, one of two American clades. The tribe was originally recognised by both Meerow (1995) and the Muller-Doblies' (1996). Its phylogenetic position within the Amaryllidoideae was established by Meerow et al. in 2000, while in-depth infratribal relationships were established in 2002.
Crininae is one of four subtribes within the tribe Amaryllideae, with a pantropical distribution (Crinum) and also sub-Saharan Africa.
Cliviinae is a small subtribe of Haemantheae, and therefore within the African clades of Amaryllidoideae. It consists of two genera, Clivia, and Cryptostephanus.
Haemanthinae is a small subtribe of Haemantheae, and therefore within the African clades of Amaryllidoideae. It consists of two genera, Haemanthus, and Scadoxus.
Gethyllidinae is a small subtribe within the amaryllis family. It is within tribe Haemantheae, and therefore within the African clades of Amaryllidoideae. It contains two genera, Gethyllis and Apodolirion, both are endemic to southern Africa.
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.
