E-book Plants and vegetation of NW Ethiopia : A new look at Rodolfo E.G. Pichi Sermolli’s results from the ‘Missione di Studio al Lago Tana’, 1937
d more in the development of science, particularly in Ethiopia, because the Italian language in which they are published is not more widely read. These results should be more widely known, and the present authors hope that this publication will help to remedy that problem. We provide commented translations of the papers that present the field observations and we analyse the updated lists of the herbarium collections. In contrast, Pichi Sermolli’s many later publications in English, mainly his work on ferns, are widely read. By reconstructing the sequence of Pichi Sermolli’s 1937 collections and databas-ing the species, we have localised his collecting localities as precisely as possible. By reconstructing and updating the identification of the collections made at each site, it has been possible to draw conclusions about the vegetation of the localities and com-pare these with both of the recent reconstructions of the natural habitats of Ethiopia, Friis et al. (2010) and Friis et al. (2022), opening up hitherto unused information. We have also connected our interpretations of the modern vegetation with Pichi Sermolli’s many photographs of landscapes, which are preserved as negatives and kept in photo-graphic archive “Fondo Missione Dainelli al Lago Tana, lotto 501” at the Società Geo-grafica Italiana in Rome.3The analysis in this paper is a much extended successor to work made for a paper by Friis (2015), where initial observations were made on the importance of Pichi Ser-molli’s 1937 collections. That paper was written to celebrate, on the 3rd of October, 2014, the centenary of the Tropical Herbarium in Florence (Centro Studi Erbario Tropi-cale), the institution which holds the most complete set of Pichi Sermolli’s collections from the Lake Tana expedition. The Tropical Herbarium in Florence was originally initiated in 1904 by Pietro Romualdo Pirotta as the Erbario Coloniale at the “La Sapi-enza” University in Rome, intended to house material coming from the Italian colo-nies of Eritrea and Somalia. But when, in 1913, a National Herbarium in Florence was planned, Pirotta, convinced of the usefulness of this initiative, accepted to move the Erbario Coloniale to Florence in 1914, in the same building as and next to the National Herbarium.
