Khat: pharmacognostical aspects.
A survey was made of the early literature on the production of khat. A botanical and micromorphological examination of 15 samples of Catha edulis was carried out and the findings were compared with data from the earlier literature on the subject. Based on earlier and present observations, the vital organs (leaves, flowers, fruit and seeds) are described, with illustrations, to assist in the identification of khat.
