Sartilmania Sennicaulis Sporathylacium Steganotheca Stockmansella (rhynialeans) Tarrantia (rhynialeans?) Tortilicaulis Uskiella (rhynialeans) It has been suggested that the poorly preserved Eohostimella, found in deposits of Early Silurian age (Llandovery, around ), may also be a rhyniophyte. Others have placed some of these genera in different groups. For example, Tortilicaulis has been considered to be a horneophyte. Rhynie flora The general term "rhyniophytes" or "rhyniophytoids" is sometimes used for the assemblage of plants found in the Rhynie chert Lagerstätte - rich fossil beds in Aberdeenshire, Scotland, and roughly coeval sites with similar flora. Used in this way, these terms refer to a floristic assemblage of more or less related early land plants, not a taxon. Though the rhyniophytes are well represented, plants with simpler anatomy, like Aglaophyton, are also common; there are also more complex plants, like Asteroxylon, which has a very early form of leaves.
