epiblem

Noun

epiblem (countable and uncountable, plural epiblems)

1. Synonym of rhizodermis.
   • Beginning now with the root of the vascular ciyptogams, it may be added that in these the epiblem is not replaced by a periderm, although a well developed hypoderma frequently takes the place of the epiblem layer, which dies and disappears.1895, Emily Lovira Gregory, Elements of Plant Anatomy, page 120
   • In the case of Anthephora pubescens, when epiblem cells and root hairs die, the cells do not lose their contents, which forms a coagulated mass that also takes on a red colour with Congo Red.1936, Transactions of the Royal Society of South Africa - Volume 23, page 4
