The species can be recognised on account of its tubular calyx, ± equal teeth, long narrow corolla tube, with the lobes less than 1/3rd their length and the galbrous filaments. The corolla tube is sometimes hairy within. The species is closely allied to the chinese Lycium barbarum Miller, from which it differs mainly in the filaments being glabrous at the base.
