Mohl's “Primordial Utricle”

Abstract

I SHOULD like to inquire, through the medium of NATURE, whether the way in which botanists now use Mohl's term “primordial utricle” is strictly accurate? In Sachs' “Lehrbuch,” and in the English translation, it is applied to the parietal layer of protoplasm found in plant cells which are old enough to have a large central vacuole, and this practice is now generally followed by English botanists.
