Contemporary vellum, manuscript title on spine, red edges (title faded). Provenance : 19th-century marginalia giving the latest classifications of each plant, a few MS additions to plate titles in Helwing's first work, bibliographical note dated 1870 (on front pastedown) -- Stadtbibliothek Königsberg (stamp on title verso) -- Robert de Belder (1921-95; sold to Bernard Quaritch Ltd., not included in the sale at Sotheby's, April 1987). AN UNUSUAL SAMMELBAND OF FOUR CLOSELY-CONNECTED WORKS ON INDIGENOUS PRUSSIAN FLOWERS. Loesel's Flora Prussica was edited by Johann Gotsched, who received the manuscript and plates from Loesel's estate, and fittingly published the work in Königsberg, the university town where Loesel had been professor of medicine (1639-1655). To this the three later works by Helwing, the first containing 12 fine etchings of anemones, form valued additions. ALL RARE.
