在第一部分中，对在Rhynie发现的硅化泥炭层进行了一般性的描述，并详细描述了一种名为Rhynia Gwynne-Vaughani的维管植物。进一步的研究表明，有两种Rhynia，我们现在区分为Rhynia Gwynne-Vaughani和Rhynia major。第一部分的叙述适用于这两个物种。与它们沿着出现的还有一种植物，其组织等级与Rhynia相似，但与该属截然不同：我们将其命名为Hornea Lignieri。另一方面，将在下一部分中描述的Asteroxylon Machiei是一种更大尺寸和更复杂形态的植物。因此，我们现在能够建立四个古老的血管隐花植物的存在和主要特征，从Rhynie床。本文对R. Gwynne-Vaughani和R.主要和Hornea Lignieri详细描述。最后，将简要地考虑事实的形态轴承。
In Part I a general account was given of the silicified peat-bed found at Rhynie, and one vascular plant was described in detail under the name of Rhynia Gwynne-Vaughani. Further study has shown that there are two species of Rhynia which we now distinguish as Rhynia Gwynne-Vaughani and Rhynia major. The account in Part I applies to both these species. Along with them there occurs a plant of similar grade of organisation to Rhynia, though quite distinct from that genus: this we name Hornea Lignieri. Asteroxylon Machiei, on the other hand, which will be described in the next part, was a plant of larger size and much more complex morphology. We are thus now able to establish the existence and main features of four archaic Vascular Cryptogams from the Rhynie bed. In the present paper additional notes on R. Gwynne-Vaughani are given, and R. major and Hornea Lignieri described in detail. In conclusion, the morphological bearings of the facts will be briefly considered.
