Description

Vegetative characteristics

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

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

The chromosome count is 2n = 16. [5]

Taxonomy

It was described as Rhodophiala laetaPhil. by Rodolfo Amando Philippi in 1860. [6] [2] A new genus EremolirionNic.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 PaposoaNic.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

The generic name Paposoa refers to Paposo, Chile. [9] The specific epithet laeta means bright, [10]

Distribution and habitat

It occurs in the Atacama and Antofagasta regions, [1] [4] where it is found in desert and desert fog oases (Lomas). [1]

Conservation

It has a restricted habitat and distribution. [5]
