160 Geology and Fossil Flora of P.E.I. 



in a memoir published about the same time with my Report, * c 

 a species which he names Walchia linearifolia, and which 

 is vfery near to W. gracilis, and especially to the variety of that 

 species figured by Mr. Eain. Knorria-like stems and specimens 

 of Sternbergia, obtained by Mr. Eain in the same beds, may all 

 belong to this species. Large Noeggerathia-like leaves, such as 

 those referred to by Mr. Bain, are not infrequent in the Permiao 

 elsewhere, and have been variously referred to ferns, to palms, and 

 to taxine trees of the type of Salisburia. I have not seen Mr- 

 Bain's specimens of these leaves.

The few plants collected by Mr. Bain in the Upper Trias, or 

 Trias proper, are especially interesting in consequence of the 

 paucity of well-preserved fossils in this formation. He finds m 

 these beds a Calami tes with very fine ribs of the type of C. 

 arenaceus, and which may be an internal cast of that Triassic 

 species, which, when perfect, is really an Equisetum rather than a 

 Calamite ; also certain Knorria-like branches different from 

 Tylodendron but probably branches of coniferous trees (Fig. 1), 

 and a species of Walchia apparently distinct from that of the 

 lower beds. It has very stout and straight branches, marked 

 with interrupted furrows. Its branchlets are long, slender and 

 crowded, and at right angles to the branch. The leaves are closely 

 appressed, triangular and scale-like. Detached branchlets have 

 thus the aspect of the Mesozoic genus Pachyphylliim, but the 



* I may remark here that I have obtained from the Permo-carbon- 

 iferous of Cape John, on the Nova Scotia coast, a leafy branch with 

 long parallel-sided obtuse leaves, and which may indicate a species 

 of Ulmannia or Voltzia, but is not sufficiently perfect for precise- 

 description.
