Mandragora caulescens, the Himalayan mandrake, is a perennial herbaceous plant in the family Solanaceae, native to the Himalayas and mountainous regions of Myanmar and south-west China.
 One of the differences from the other species of "Mandragora" is that it has a stem, whereas they are stemless.
 Like all species of "Mandragora", it contains tropane alkaloids, making it toxic.
 It is used in traditional Chinese medicine.
Mandragora are a space rock/world dance-music band from Brighton, England, whose formative output can be described as psychedelic rock with ethnic sounds and tribal rhythms.
 Formed in 1983, the band have released 5 albums of their own, and a collaborative album with Phil Thornton.
 They built up a loyal following on the free festival circuit of the 1980s and 1990s, and were signed to Delerium Records.
 In recent years Mandragora have evolved into a world music/electronic dance act featuring singers and musicians from all corners of the globe.
Celastrus, commonly known as staff vine, staff tree or bittersweet, is a genus in the Celastraceae family which comprises about 30-40 species of shrubs and vines.
 They have a wide distribution in East Asia, Australasia, Africa, and the Americas.
Mandragora Movies was started in Bucharest, Romania in 2004 by Romanian film producer, film director, screenwriter and businessperson .
 Mandragora International Group also opened French and American subsidiaries in Paris and New York.
Mandragora is a plant genus belonging to the nightshade family (Solanaceae).
 Members of the genus are known as mandrakes.
 There are between three and five species in the genus.
 The one or two species found around the Mediterranean constitute the mandrake of ancient writers such as Dioscorides.
 Two or three further species are found eastwards into China.
 All are perennial herbaceous plants, with large tap-roots and leaves in the form of a rosette.
 Individual flowers are bell-shaped, whitish through to violet, and are followed by yellow or orange berries.
Mandragora officinarum is the type species of the plant genus "Mandragora".
 It is often known as mandrake, although this name is also used for other plants.
 s of 2015 , sources differ significantly in the species they use for "Mandragora" plants native to the Mediterranean region.
 In the narrowest circumscription, "M. officinarum" is limited to small areas of northern Italy and the coast of former Yugoslavia, and the main species found around the Mediterranean is called "Mandragora autumnalis", the autumn mandrake.
 In a broader circumscription, all the plants native to the countries around the Mediterranean Sea are placed in "M. officinarum", which thus includes "M. autumnalis".
 The names autumn mandrake and Mediterranean mandrake are then used.
 Whatever the circumscription, "Mandragora officinarum" is a perennial herbaceous plant with ovate leaves arranged in a rosette, a thick upright root, often branched, and bell-shaped flowers followed by yellow or orange berries.
Mandragora turcomanica, the Turkmenian mandrake, is a perennial herbaceous plant in the family Solanaceae, native to the Kopet Dag mountains in Turkmenistan and one location in neighbouring Iran.
 It differs from the mandrakes found around the Mediterranean ("Mandragora autumnalis" and/or "Mandragora officinarum") chiefly by being larger.
Mandragora autumnalis, known as mandrake or autumn mandrake, is recognized by some sources as a separate species from "Mandragora officinarum", although with different circumscriptions.
 Others regard it as merely part of this very variable species.
 Plants given the name "Mandragora autumnalis" consist of a rosette of leaves up to 60 cm across, close to the ground, with a central group of usually purplish flowers followed by yellow or orange berries.
 The large tap-roots as well as the leaves contain alkaloids and are toxic.
 They have traditional uses as herbal medicines.
Celastrus orbiculatus is a woody vine of the Celastraceae family.
 It is commonly called Oriental bittersweet.
 Other common names include Chinese bittersweet, Asian bittersweet, Round-leaved bittersweet, and Asiatic bittersweet.
 "Celastrus orbiculatus" was introduced into North America in 1879, and is considered to be an invasive species in eastern North America.
 It closely resembles the native North American species, "Celastrus scandens", with which it will readily hybridize.
Celastrus scandens, commonly called American bittersweet or bittersweet, is a species of "Celastrus" that blooms mostly in June and is commonly found on rich, well-drained soils of woodlands.
 It is a sturdy perennial vine that may have twining, woody stems that are 30 ft or longer and an inch or more thick at the base.
 The stems are yellowish-green to brown and wind around other vegetation, sometimes killing saplings by restricting further growth.
 It has tiny, scentless flowers at the tips of the branches.
 It has colorful, orange fruits that are the size of a pea.
 These fruits are poisonous to humans when ingested, but are favorites of birds.
 "C. scandens" roots were used by Native Americans and pioneers to induce vomiting, to treat venereal disease, and to treat symptoms of tuberculosis.
