Lycium depressum is a plant type from the genus of Lycium ( Lycium ) in the family of the nightshade family (Solanaceae).
description
Lycium depressum is a 1.5 to 2.5 m high, with spines reinforced shrub . The leaves are 20 to 50 mm long and 4 to 17 mm wide. The leaf blade is elongated, inversely lanceolate to elliptically elongated, elliptically lanceolate or lanceolate to narrowly lanceolate. The tip is blunt to almost pointed, the base wedge-shaped.
The flowers are single or in clusters of two to six on 5 to 7 mm long pedicels . The calyx is more or less cup-shaped, the calyx lobes are irregular, can be blunt or pointed and are finely haired. The crown is pale purple to purple in color. The corolla tube is 4 to 5 mm long, hairless and funnel-shaped. The length of the corolla lobes corresponds to about a third of the length of the corolla tube, the corolla lobes are ciliate. The stamens protrude beyond the crown, the stamens are hairless at the base.
The fruit is a red, spherical berry 5 to 6 mm in diameter . The seeds are kidney-shaped, brown, about 2 mm long and finely reticulated and pitted.
The flower stalk on the fruit extends up to 24 mm.
The number of chromosomes is 2n = 24.
Occurrence
The species occurs in West Asia, Central Asia, the Caucasus and Pakistan.
Systematics
According to molecular biological studies, the species is most closely related to Lycium europaeum . Both are classified in a large monophyletic clade of ancient species of the genus, but the exact relationships within the clade are still unclear.
