From Wikipedia, the free encyclopedia
Alstroemeria[1] is a South American genus belonging to the Alstroemeria family, composed of 124 species distributed from southern Venezuela to southern Argentina and Chile.
The genus was named by Carl Linnaeus in honor of his friend, the Swedish botanist Clas Alströmer, who was the first to collect seeds of these species in South America and send them to Europe in 1753.
Alstroemeria plants are tuberous or rhizomatous and perennial. Each erect stem has a foliage of a few lanceolate leaves and ends in an umbel of 3 to 10 flowers. These have 6 tepals with markings and patches of contrasting colors. The basic chromosome number of the genus is x = 8.[2][3][4]

The exact number of species is difficult to determine because new taxa[5][6][7][8] are constantly being discovered and there are also nomenclatural problems that determine that many of the names cited are actually synonymies.[9][10][11] The following is a list of the species of the genus Alstroemeria accepted up to March 2010, in alphabetical order. For each species, the binomial name is given followed by the author, abbreviation according to convention and usage, and the valid publication.[12] Finally, for each species, its geographic distribution is also detailed.[13]
The nothospecies of the genus, that is, those taxa that have been shown to owe their origin to hybridization between two different species (for example, Alstroemeria × davisiae which is the hybrid between A. pelegrina and A. pulchella) are listed below together with their parental species where these are known:[13]
The following names are considered synonyms of Alstroemeria:[13]
