Duboisia hopwoodii
''Duboisia hopwoodii'' is a shrub native to the arid interior region of Australia. Common names include pituri, pitchuri thornapple or pitcheri. It has an erect habit, usually growing to between 1 and 3 metres in height and has long, narrow leaves.〔〔 Flowers are white and bell-shaped with violet-striped throats. These appear between June and November in the species native range followed by purple-black, rounded berries which are 3 to 6 mm in diameter.〔
==Pituri==
(詳細はIndigenous Australians mix the dried leaves of a small population of ''D. hopwoodii'' growing around the Mulligan River with wood ash to make a variety of pituri, the traditional Aboriginal chewing mixture. ''D. hopwoodii'' plants from this region are high in nicotine and low in the much more toxic drug nornicotine, whereas those found in some other parts of Australia can have very high levels of nornicotine and are sometimes used to contaminate water holes and stun animals to help in hunting.〔(【引用サイトリンク】title=Duboisia hopwoodii - Pituri Bush )〕 The paleontologist Dr Gavin Young named the fossil agnathan ''Pituriaspis doylei'' after the plant, as he thought he might be hallucinating, as though under the effects of pituri, upon viewing the fossil fish's bizarre form.〔Long, John A.
