Catha Edulis
Khat or qat ( ''ch’at''; Oromo: ''Jimaa'', so, qaad, khaad, khat or chat, ar, القات ''al-qāt'') is a flowering plant native to eastern and southern Africa. Khat contains the alkaloid cathinone, a stimulant, which is said to cause excitement, loss of appetite, and euphoria. Among communities from the areas where the plant is native, khat chewing has a history as a social custom dating back thousands of years analogous to the use of coca leaves in South America and betel nut in Asia. The World Health Organization (WHO) classified it in 1980 as a drug of abuse that can produce psychological dependence, although the WHO does not consider khat addiction to be a serious problem. The legality of khat varies by region. In many countries, khat might not be a specifically controlled substance but may nevertheless be illegal under more general laws. It is a specifically controlled substance in some countries including Canada, Germany, the United Kingdom, and the United States ...

International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized author abbreviations. These were initially based on Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew (Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium ( APNI). The IPNI database is a collection of the names registered by the three cooperating institutions and they work towards standardizing the information. The stan ...
