Nothia aphylla
Nothia was a genus of Early Devonian vascular plants whose fossils were found in the Rhynie chert in Scotland. It had branching horizontal underground stems (rhizomes) and leafless aerial stems (axes) bearing lateral and terminal spore-forming organs (sporangia). Its aerial stems were covered with small 'bumps' (emergences), each bearing a stoma. It is one of the best described early land plants. Its classification remains uncertain, although it has been treated as a zosteroph… http://taylorlab.berkeley.edu/sites/default/files/taylorlab/publications/berbee2007a.pdf

WebFeb 1, 2007 · Nothia aphylla is a small sporophyte with possible affinities in the Zosterophyllophyta. The plant consists of an aerial system of dichotomously branching orthotropic axes that arise from prostrate rhizomatous axes ( Fig. 1a–c ).

WebThis reconstruction of the sporangia of Nothia aphylla was made by El-Saadawyg and Lacey (1979).Nothia is a rare plant in the Rhynie Chert and it is not yet completely understood. Kidston and Lang thought the sporangia to belong to the plant Asteroxylon, but it turned out to be a new plant. The stem of Nothia shows a peculiar wavy surface. WebIn this view, the "zosterophylls" comprise a paraphyletic group, ranging from forms like Hicklingia, which had bare stems, to forms like Sawdonia and Nothia, whose stems are covered with unvascularized spines or enations. The genus Renalia illustrates the problems in classifying early land plants.
