Lycium pallidum is a plant type from the genus of Lycium ( Lycium ) in the family of the nightshade family (Solanaceae). The fanatics Sagenosoma elsa feeds probably monophag by plants.
description
Lycium pallidum is a 1 to 2 m high, dense and tangled branched shrub that is armed with spines . The leaves are frosted, hairy glandular and 10 to 15 mm long and 3 to 15 mm wide.
The flowers are hermaphroditic and five-fold. The calyx is cup-shaped to bell-shaped and has a bluish frosting. The calyx tube becomes 5 to 8 mm long, the calyx lobes are about as long as or longer than the calyx tube. The crown is lanceolate to ovate or elliptical in shape and colored white to lavender-purple, but mostly greenish with purple veins. The corolla tube reaches a length of 12 to 25 mm, the length of the corolla lobes corresponds to 1/5 to 1/3 of the length of the corolla tube. The stamens are densely hairy almost to the edge of the corolla tube.
The fruit is a red or reddish-blue, egg-shaped berry that reaches a diameter of 10 mm or less. It contains four to 50 seeds .
The number of chromosomes is 2n = 24.
Occurrence
The species is distributed in North America and occurs there in the Mexican states of Coahuila , Nuevo León , San Luis Potosí and probably in northern and eastern Chihuahua , as well as in the US states of Arizona , California , Nevada , Utah , Colorado , New Mexico and Texas in front.
Systematics
Internal system
Two varieties are distinguished within the species:
- Lycium pallidum var. Pallidum
- Lycium pallidum var. Oligospermum C.L. Hitchc.
External system
Molecular biological studies place the species together with Lycium cooperi , Lycium macrodon , Lycium puberulum and Lycium shockleyi in a clade that is a sister clade to the genus Grabowskia within the genus Lycium .
