Blume, C.L. Museum Botanicum. 2 volumes. The dates given by BLUME for each separate part of volume 1 (1849-1851) seem always to have been considered to be correct. However, those of the 2nd volume are partly wrong: the preface is dated 1852, and may have been printed at that time, but the book was then not distributed. Each part consists of 16 pages.
