?bu ?an?fah mad ibn Daw?d D?nawar? (815-896 CE, Arabic: ?) was an Islamic Golden Age polymath, astronomer, agriculturist, botanist, metallurgist, geographer, mathematician, and historian. He was born in the region of Dinawar, in Kermanshah in modern-day western Iran. He studied astronomy, mathematics and mechanics in Isfahan and philology and poetry in Kufa and Basra. He died in Dinawar. His most renowned contribution is Book of Plants, for which he is considered the founder of Arabic botany. There is no consensus regarding his ethnic background among scholars. Ludwig Adamec considers him to be of Kurdish descent, while Encyclopedia of Islam classifies him as an Arabphilologist and scientist, however, Encyclopaedia Iranica lists him as Persian.Encyclopædia Britannica Online classifies him to be of Kurdish origin. Neutral academics consider him to have been Kurdish, while encyclopedia's with a clear bias prefer to list him as belonging to their own ethnicity (Persian according to Encyclopedia Iranica, Arab according to Encyclopedia of Islam). 
He is the author of about fifteen works
His General History (al-Akhbar al-Tiwal) has been edited and published numerous times (Vladimir Guirgass, 1888; Muhammad Sa'id Rafi'i, 1911; 'Abd al-Munim 'Amir & Jamal al-din Shayyal, 1960; Isam Muhammad al-Hajj 'Ali, 2001), but has not been translated in its entirety into a European language. Jackson Bonner has recently prepared an English translation of the pre-Islamic passages of al-Akhbar al-Tiwal.
Al-Dinawari is considered the founder of Arabic botany for his Kitab al-Nabat (Book of Plants), which consisted of six volumes. Only the third and fifth volumes have survived, though the sixth volume has partly been reconstructed based on citations from later works. In the surviving portions of his works, 637 plants are described from the letters sin to ya. He describes the phases of plant growth and the production of flowers and fruit.
Many of the Muslim early Botanical works are lost, such as that of Al-Shaybani (d.820), Ibn Al-Arabi (d.844), Al-Bahili (d.845) and Ibn as-Sikkit (d.857), but their works, however, are extensively quoted in later books by Abu Hanifa Al-Dinawari.
Parts of al-Dinawari's Book of Plants deals with the applications of Islamic astronomy and meteorology to agriculture. It describes the astronomical and meteorological character of the sky, the planets and constellations, the sun and moon, the lunar phases indicating seasons and rain, the anwa (heavenly bodies of rain), and atmospheric phenomena such as winds, thunder, lightning, snow, floods, valleys, rivers, lakes, wells and other sources of water.
Parts of al-Dinawari's Book of Plants deals with the Earth sciences in the context of agriculture. He considers the Earth, stone and sands, and describes different types of ground, indicating which types are more convenient for plants and the qualities and properties of good ground.
Abu Hanlfah al-DInawarl was a Persian of liberal outlook, who took an interest in botany among other sciences.
