Arabische Pflanzennamen aus Aegypten, Algerien und Jemen (Arabic plant names from Egypt, Algeria, and Yemen) is a book on botanical names of plants native to these three countries. It is comprised almost entirely of lists of plant names, alphabetically ordered in Latin and Latinized Arabic, but sometimes also in Arabic. The book is organized into six sections: (1) Arabische Pflanzennamen aus der Flora von Aegypten (Arabic plant names for the flora of Egypt); (2) Arabische Pflanzennamen aus der Flora von Jemen nach Forskal (Arabic plant names for the flora of Yemen according to Forskal); (3) Arabische Pflanzennamen aus der Flora von Jemen und Süd-Arabien (Arabic plant names for the flora of Yemen and South Arabia); (4) Arabische Pflanzennamen aus der Flora von Biskra (Arabic plant names for the flora of Biskra [in the northern Algerian desert]); (5) Arabische Pflanzennamen aus dem Küstenland und dem Tel-Bergland von Nordwest-Algerien (Arabic plant names from the coastland and mountains of northwestern Algeria); and (6) Arabische Nomenklatur der Datel-Palme in Aegypten und Algerien (Arabic terminology of the date palm in Egypt and Algeria). An introduction discusses the writing of the Arabic alphabet with Latin letters. The author is Georg August Schweinfurth (1836−1925), a Baltic German botanist, who studied at the universities of Heidelberg and Munich. He is mostly known for his travels in Sudan and the Congo-Nile watershed regions, and his discovery of the Uele River (a tributary of the Congo). Some of his Central Africa travel is preserved in his Im Herzen von Afrika: Reisen und Entdeckungen im centralen äquatorial-Afrika während der Jahre 1868 bis 1871, translated into English as The Heart of Africa: Three Years' Travels and Adventures in the Unexplored Regions of Central Africa from 1868 to 1871. The book presented here, however, is the result of Schweinfurth’s later travels and research in other regions, namely North Africa and Arabia, including the period 1875−88 when he lived in Cairo, where he established a geographical society with the support of Khedive Ismail. Peter Forskal (also seen as Forsskål, 1732−63) was a Swedish naturalist who accompanied German explorer Carsten Niebuhr on his expedition to Arabia, arriving in Yemen in 1762. Forskal began working diligently on area plants but died of malaria seven months later.
