WebAug 1, 1979 · The most relevant of these are the stomata of Nothia aphylla. These also occur at tips of emergences or projections, not only on the sporangia, but also on their stalks and the stems bearing them (E1-Saadawy and Lacey, 1979). Stomata on the stems of Horneophyton were reported by Zimmermann (1927), and projections by Eggert (1974).
