S54 PEOCiEEDINGS OF THE GEOLOGICAL SOCIETY. [April 24, 



what has already been remarked in regard to the wide range of the 

 Palaeozoic plants. 



I have previously recorded a species of Lepidodenclron from South 

 Africa, which cannot be separated from a common British species, 

 and a species of Flemingites from South Brazil, closely allied to that 

 of our own Coal-measures. 



There is a small group of Lepidodendra in the Coal-measures, 

 which by the form of their scars are closely related to this Devonian 

 species. Indeed there are no characters in the portions yet known 

 of them which justify their separation specifically from the Devo- 

 nian plant. It cannot be doubted, however, that this is the result 

 of our imperfect knowledge of these plants. The group I refer to 

 is that for which Presl proposed the generic name Bergeria (Stern- 

 berg, Flora Vorw. vol. ii. p. 184) ; and if a new generic name is 

 required to separate them from Lepidodendron proper, this, of course, 

 must be adopted. "We may add to the forms enumerated by Presl 

 as belonging to this group the two following fossils : — Lepidophloios 

 tetragonus, Dawson, and Lepidodendron tetragonum, Geinitz (non 

 Sternb.). 



Among the Devonian fossils presented by the Rev. W. B. Clarke 

 to the Society's Museum, there is a fragment of a Lepidodendroid 

 plant which I cannot separate from that found at Kiltorkan, to 

 which Dr. Haughton gave the name of Sigillaria dichotoma, and after- 

 wards of Cyclostigma TciltorTcense, and which, after receiving many 

 other aliases, should be named, I believe, Syringodendron dicho- 

 tomum, it being a species of tbat genus as amended by Brongniartin 

 his ' Histoire,' and again in his ' Tableau.' 



A small fragment in Mr. Daintree's collection seems to indicate a 

 third species of Lepidodendron, allied to if not identical with Sage- 

 naria ohovata, Eichwald. I cannot, however, be certain, from the 

 single specimen, whether the markings are on the surface of the 

 stem, and so sufficient to warrant its specific determination. 



Portions of the rachis of a fern like those to which Baily has given 

 the name of Filicites Uneatus, and fragments of a Calamites (it may 

 be C. radiatus, Brongn.), complete the list of Mr. Daintree's Devo- 

 nian plants. 



The remaining fossil plants Mr. Daintree refers to two horizons, 

 the older characterized by the presence of Glossopteris Browniana, 

 Brongn., and the younger by Tceniojyteris Daintreei, M'Coy. 



Glossopteris Broivniana has been so frequently described and 

 figured, that I find nothing additional worth recording from an 

 examination of Mr. Daintree's specimens, unless it be that one 

 shows some indications of fruit in the form of linear sori running 

 along the veins, and occupying a position somewhat nearer to the 

 margin of the frond than to the midrib. 



In addition to the species which I have desci'ibed and figured, 

 there are associated with Glossopteris fragments of a small species 

 of Sehizopteris, apparently bearing fruit on the apex of the truncate
