Lycium cestroides is a plant species from the genus of the buckthorn ( Lycium ) inthe nightshade family (Solanaceae).
description
Lycium cestroides is a mostly 1 to 2 m high, upright shrub that can rarely reach heights of up to 5 m. The leaves are hairless and 10 to 90 mm long and 4.5 to 47 mm wide.
The flowers are hermaphroditic and usually five-fold, but four-, six-, eight- or nine-fold flowers are rarely found. The calyx is tubular or sometimes also bell-shaped, the calyx tube is 2 to 3.5 mm long and covered with 1 to 2.5 mm long calyx tips. The crown is tubular to funnel-shaped and has a solid, intense purple color. The stamens are hairy on about 1 to 2 mm of the lower part of the base.
The fruit is a red, orange or dark purple, spherical to ovoid berry with a length of 5 to 9 mm and a width of 4 to 8 mm.
The number of chromosomes is 2n = 24.
Occurrence
The species is widespread in South America and occurs there in Argentina and Bolivia .
Systematics
Molecular biological studies place the species as a sister species to a large clade that only contains American species of the genus. This ranking is only supported by a bootstrap value of 76%, but flower morphology and the resulting specialization in hummingbirds as pollinators indicate a special role among the American representatives of the genus.
