The term "devil dance" was an early 20th century description of the performance, derived from Western perceptions of the costumes worn by performers.[5]

Phylogeny
Cannabis likely split from its closest relative, Humulus (hops), during the mid Oligocene, around 27.8 million years ago according to molecular clock estimates. The centre of origin of Cannabis is likely in the northeastern Tibetan Plateau. The pollen of Humulus and Cannabis are very similar and difficult to distinguish. The oldest pollen thought to be from Cannabis is from Ningxia, China, on the boundary between the Tibetan Plateau and the Loess Plateau, dating to the early Miocene, around 19.6 million years ago. Cannabis was widely distributed over Asia by the Late Pleistocene. The oldest known Cannabis in South Asia dates to around 32,000 years ago.[92]

Taoism
Beginning around the 4th century, Taoist texts mentioned using cannabis in censers. Needham cited the (ca. 570 AD) Taoist encyclopedia Wushang Biyao (Chinese: 無上秘要) ("Supreme Secret Essentials") that cannabis was added into ritual incense-burners, and suggested the ancient Taoists experimented systematically with "hallucinogenic smokes".[65] The Yuanshi shangzhen zhongxian ji 元始上真眾仙記 ("Records of the Assemblies of the Perfected Immortals"), which is attributed to Ge Hong (283-343), says:

For those who begin practicing the Tao it is not necessary to go into the mountains. … Some with purifying incense and sprinkling and sweeping are also able to call down the Perfected Immortals. The followers of the Lady Wei and of Hsu are of this kind.[66]
Lady Wei Huacun (Chinese: 魏華存) (252-334) and Xu Mi (Chinese: 許謐) (303-376) founded the Taoist Shangqing School. The Shangqing scriptures were supposedly dictated to Yang Xi (Chinese: 楊羲) (330-c. 386) in nightly revelations from immortals, and Needham proposed Yang was "aided almost certainly by cannabis". The Mingyi bielu (Chinese: 名醫別錄) ("Supplementary Records of Famous Physicians"), written by the Taoist pharmacologist Tao Hongjing (456-536), who also wrote the first commentaries to the Shangqing canon, says, "Hemp-seeds (Chinese: 麻勃) are very little used in medicine, but the magician-technicians (shujia 術家) say that if one consumes them with ginseng it will give one preternatural knowledge of events in the future."[67][68] A 6th-century AD Taoist medical work, the Wuzangjing (Chinese: 五臟經) ("Five Viscera Classic") says, "If you wish to command demonic apparitions to present themselves you should constantly eat the inflorescences of the hemp plant."[69]

Joseph Needham connected myths about Magu, "the Hemp Damsel", with early Daoist religious usages of cannabis, pointing out that Magu was goddess of Shandong's sacred Mount Tai, where cannabis "was supposed to be gathered on the seventh day of the seventh month, a day of seance banquets in the Taoist communities."[70]

One of 10 ancient Chinese incense burners, known as braziers, found in the 2,500-year-old cemetery with burned cannabis residues high in THC.
Update: On June 12, 2019, archaeologists reported a new and striking discovery in the Xinjiang province: 10 wooden incense burners, known as braziers, with cannabis residues inside eight tombs in the Jirzankal Cemetery dating back to 500 BC, which is the same time period when the previous plant material was found. Tests determined that there were higher levels of THC than in the past, leading to the speculation that the cannabis was used (but not literally smoked) for intoxication purposes.

“We can start to piece together an image of funerary rites that included flames, rhythmic music and hallucinogen smoke, all intended to guide people into an altered state of mind,” the researchers write in the study published in the journal Science Advances.

In 2016, Archeologists found 13 well-preserved cannabis plants at a 2,500-year-old burial site in Western China. Writing in the journal Economic Botany, researchers described the discovery as “an extraordinary cache of ancient, well-preserved Cannabis” that “appear to have been locally produced and purposefully arranged and used as a burial shroud.” The plants were displayed on top of a corpse in a tomb at Jiayi cemetery in Turpan in the Xinjiang region.

In 2008, archeologists discovered another cache of ancient cannabis in the area in the grave of a shaman. Xinjiang has a long history with cannabis—from the ancient Subeixi culture to the Muslim Uyghurs who continue their tradition of hash-making to this day.


Ancient cannabis stalks and leaves found amongst bones in Western China in 2016.

The plant finding marks the first time complete cannabis material from this time period has been discovered. It also confirms what archeologists have long suspected: that cannabis was cultivated in the region at the time. And like previous parts of ancient cannabis plants that were found, “researchers suspect that this marijuana was grown and harvested for its psychoactive resin,” reports National Geographic.

While cannabis plants have many uses, scientists think that this ancient population cultivated cannabis for its psychoactive properties since they haven’t located any hemp textiles in the area, and the seeds are too small to serve as a source of nutrition. The flowers of the discovered plants were resinous and hairy, and so well preserved that the trichomes were still visible.

Other archeological evidence from Eurasia had residue of opium and cannabis that were apparently used for “drug-fueled rituals.” Ancient Chinese medicine texts also contained references to the psychoactivity of cannabis and other plants, Freedom Leaf previously reported.

Earlier in 2016, a review of archeological records suggested that cannabis may have played a crucial role in human migration patterns 5,000 years ago. The early migrants’ routes eventually evolved into the Silk Road. The research suggests that the cannabis trade may have helped fuel this ancient migration that contributed to the rise of European and Asian civilizations.

“The two things happened at the same time,” reports the Influence. “The Yamnaya spread out across the continent, and cannabis cultivation flourished in their wake.”

A lectotype is a designated specimen selected from a group of syntypes (original material) when a holotype (original, designated type specimen) is not available or when the original type material consists of multiple specimens. It serves as the reference point for the name of the species or taxon.

Here's a more detailed explanation:
  • Syntypes:
    When a species is first described, the original material used for the description may consist of multiple specimens. Each of these specimens is considered a syntype.

  • No Holotype or Holotype Missing:
    If the original description didn't designate a holotype, or if the designated holotype is lost or destroyed, a lectotype can be chosen from among the syntypes.

  • Multiple Original Specimens:
    If the original description included more than one specimen, a lectotype can be selected to serve as the definitive reference.

  • Lectotype as the Reference:
    Once a lectotype is selected, it becomes the definitive reference for that species name. If there's any doubt about the correct application of the name, the lectotype must be consulted.

  • Type Locality:
    The location where the lectotype (and by extension, the species) is found is the type locality.
In simpler terms: Imagine you're describing a new type of butterfly, and you have several specimens of it. You could choose one of those specimens as the lectotype to be the "official" example of that species if a holotype wasn't originally designated, or if the holotype is missing.
