Mature leptoids of the gametophytes ofPolytrichadelphus magellanicus (Bryophytes) share various characteristics with sieve elements of true vascular plants. Degenerated nuclei, however, persist in these cells, which also retain small vacuoles. Their end walls present many enlarged plasmodesmata. Endoplasmic reticulum and vesicles occasionally accumulate near these walls. The possible role in translocation of certain of the observed structures is discussed.
