摘要：
Naked branched axes associated with sporangia, originally described by Kidston and Lang (1920) as the probable fertile region of Asteroxylon mackiei, were later shown by Lyon (1964) to belong to an unknown plant which he named Nothia aphylla. The name was validated by Høeg in 1967. Nothia aphylla is described here in greater detail from new material collected from the Rhynie locality. The sporangia are lateral in terminal branched spikes. Their arrangement ranges from spiral to semiverticillate. The fertile axes terminate in clusters of 2-5 sporangia. The stalked sporangia are rather reniform with a distal transversely-extended dehiscence slit. Systematically Nothia has similarities to both Zosterophyllophytina and Rhyniophytina. © 1979.
