"Lehrbuch der Botanik für Hochschulen" by Strasburger, Noll, Schenck, and Schimper is a botanical textbook first published in 1894. Known simply as "Strasburger," this work became the "Bible of botanists" in German-speaking regions shortly after its debut. For over a century, four rotating university professors maintained its comprehensive coverage of all botanical aspects, from cellular biology to plant geography. The textbook has been translated into multiple languages and remains a standard reference today.
