Native of the Himalaya, and quite hardy at Kew, where it flowers in May and June. It was in cultivation there in 1853, and had probably been introduced by Sir Joseph Hooker a few years previously. This plant yields the drug known as ‘Lycium’, used for ages in inflammatory affections of the eyes. The beautiful purplish berries are eaten in N. India. It is a species distinct in the hard, pale green leaves, conspicuously net-veined above, glaucous beneath, and almost entire.
