Aberdeenshire, now in course of publication by the Royal 

 Society of Edinburgh. Two species of Rhynia are now dis- 

 tinguished: R. Gwynne-Vaughani and R. major. The latter 

 is larger in all its parts than R. Gwynne-Vaughani and differs 

 in some details of the anatomy. These plants are rootless 

 and leafless and consisted of a subterranean rhizome with 

 $ rhizoids, dichotomously branched cylindrical aerial stems and 

 large terminal sporangia. 



Another equally simple plant, associated with these in the 

 Family Rhyniaceae, has been discovered and investigated. 

 This is named Hornea Lignieri and consisted of rhizomes, 

 branched stems, and terminal sporangia, without roots or 

 leaves. The rhizomes were lobed parenchymatous structures, 

 suggesting comparison with the protocorm of certain species 

 of Lycopodium. The stems branched dichotomously, and had 

 a simple central cylinder, cortex, and epidermis. No stomata 

 have yet been discovered in this plant, as they have in Rhynia, 

 but its organisation suggests a similar land-habit. The 

 sporangia are remarkable in the presence of a columella-like 

 central region making the spore cavity' dome-shaped. 



These simple Vascular Cryptogams suggest comparisons 

 with Bryophyta and Algae.
