WebFeb 1, 2024 · Poricidal dehiscence in nine of the species is accomplished by resorption and/or collapse tissues. Resorption tissue alone occurs in two species, both in one, and six species have only collapse tissue. Cells of both tissues are initially meristematic. Resorption tissue develops crystals and breaks down in the same way as granular pouches. Webspecies of Lycianthes typically have poricidal anther dehiscence.
