| 520 | _a"Aufzählung und Beschreibung der Acacien-Arten des Nilgebiets" by Schweinfurth is a scientific botanical monograph written in the late 19th century. It catalogues and diagnoses the Acacia species of the Nile basin and Red Sea littoral, emphasizing morphology, variability, distribution, and indigenous names. Aimed at botanists and collectors, it prioritizes field-observed traits of stems, bark, spines, leaves, flowers, and pods while reconciling herbarium material with travel-based study. The opening of the monograph explains the author’s motivation after a journey to Egypt: existing literature and herbaria left key “character plants” of the region insufficiently understood, prompting a focused study of Acacia as dominant trees from deserts to tropical-rain zones. He reports 24 wild species for the Nile region, expands on Bentham’s earlier work, and details the specimens and herbaria consulted, noting gaps (e.g., Indian and Senegambian material). A methodological preface stresses how climate, season, and even branch position can alter diagnostic features—spines, stipules, leaf division, and glands—warning against hasty species splitting. He then outlines stable floral characters, the role of bracts on peduncles, and seed traits, provides a comparative table, and introduces a key dividing Gummiferae and Vulgares. The text proceeds to Latin diagnoses and German notes for individual species with habitats and vernacular names. Early highlights include spirocarpa with desert and rain-belt forms, tortilis of the wadis, nilotica prized for tannin-rich pods, verugera with extraordinarily long spines, fistula whose insect-swollen thorns whistle in the wind, and Seyal with cinnamon-colored bark and falcate pods.
