Abstract
This part of the account of our examination of the plants preserved in the silicified peat-bed of early Old Red Sandstone age found at Rhynie will be devoted to the consideration of a number of general questions concerning the four Vascular Cryptogams which it has yielded.1. In the first place the morphological characters of Rhynia Gwynne-Vaughani, R. major, Hornea, and Asteroxylon will be reviewed and the attempt made to reconstruct the external appearance of these plants as they grew. In relation to this a few additional features of the plants will be described.2. This will lead naturally to a consideration of the general bearings upon plant-morphology of the facts mentioned in this series of papers.Keywords
