Lycium athium is a plant type from the genus of Lycium ( Lycium ) in the family of the nightshade family (Solanaceae).
description
Lycium athium is an upright shrub 1 to 1.5 m tall . Its leaves are succulent and hairless. They become 3 to 12 mm long and 1 to 3 mm wide.
The flowers are hermaphrodite and fourfold. The calyx is bell-shaped and hairless. The calyx tube is 1.5 to 2 mm long, the calyx lobes 0.5 to 0.8 mm. The crown is funnel-shaped and colored white, whitish-green or yellow-green. The corolla tube has a length of 2.5 to 3 mm, the corolla lobes are 1.5 to 2 mm long. The base of the stamens is hairy tomentose.
The fruit is an orange or red, spherical berry that is 5 to 6 mm long and 3.3 to 4 mm wide. It contains two seeds .
Occurrence
The species is widespread in South America and occurs there in Argentina in the province of Formosa .
Systematics
Molecular biological studies place the species as a sister species to Lycium minimum . Both species have stone fruit-like fruits with two seeds, as they occur in a similar way in the not closely related species Lycium californicum and Lycium ameghinoi . In the latter, however, the fruits are completely woody, which does not occur with Lycium athium and Lycium minimum .
