Paposoa laeta is the only species of the monotypic genus Paposoa in the family Amaryllidaceae endemic to northern and central Chile.[3]
Description
[edit]Vegetative characteristics
[edit]Paposoa laeta is a bulbous,[4] over 10 cm tall plant with ovoid,[5] tunicate bulbs[4] bearing flat,[6] linear,[4] 30–60 cm long, and 5–9 mm wide leaves.[5]
Generative characteristics
[edit]The inflorescence with a hollow,[6] 10–30 cm long, and 2–4 mm wide scape[5] bears 1–7[4] violet to purple,[6] zygomorphic flowers.[5] The flowers have 6 tepals. The androecium consists of 6 stamens. The gynoecium consists of 3 carpels. The trilocular capsule fruit bears flat,[4] shiny, black seeds.[5]
Cytology
[edit]The chromosome count is 2n = 16.[5]
Taxonomy
[edit]It was described as Rhodophiala laeta Phil. by Rodolfo Amando Philippi in 1860.[6][2] A new genus Eremolirion Nic.García was described by Nicolás García Berguecio in 2019,[5] but due to confusion with the similarly named Eremiolirion J.C.Manning & F.Forest (Tecophilaeaceae), a new genus Paposoa Nic.García and species Paposoa laeta (Phil.) Nic.García was required and published by García in 2020.[7] Within the tribe Hippeastreae, it is placed in the subtribe Traubiinae.[8]
Etymology
[edit]The generic name Paposoa refers to Paposo, Chile.[9] The specific epithet laeta means bright,[10]
Distribution and habitat
[edit]It occurs in the Atacama and Antofagasta regions,[1][4] where it is found in desert and desert fog oases (Lomas).[1]
Conservation
[edit]It has a restricted habitat and distribution.[5]
