Zur Lehre vom Wachsthum der Pflanzenzelle.

Erste Ausgabe. - "Cohn's work on P. pluvialis also marked an important advance toward a redefinition of the cell and toward a recognition that Schleiden had placed too much emphasis on the cellulose cell wall. By suggesting, like Braun, that there existed primordial plant cells (motile swarm cells) devoid of cellulose walls, Cohn confirmed and expanded the suggestions of Nägeli, Mohl, Braun, and others that the essential constituent of the cell was its protoplasmic contents" (DSB). - Vereinzelt gering stockfleckig, sonst gut erhalten. - DSB 3, 336
