(Centuriae Octavae Fasciculus Secundus Totiusque Operis Ultimus)
A botanical plate book from 1812 by Joseph Jacob von Plenck, edited by Joseph Lorenz Kerndl and published in Vienna by the Geistinger'sche Buchhandlung and Rudolph Gräffer & Comp., for botanists and naturalists. The hand-coloured plates show ferns and a cycad, each drawn whole with roots, fronds, and separate enlarged details of spore clusters and sori on the leaf undersides, a clear model for scientific specimen layouts.
