Kidston, R., Notes on some Scottish floras oi Lower 

 Carboniferous age. (Summary of Progress of the Geo- 

 logical Survey of the United Kingdom for 1903 [without titre]. 

 1903. p. 130—137.) 



From the Campbeltown Coalfield, among other Lovver 

 Carboniferous plants, Sphenopteris elegans Brong., Sphenopteris 

 Linki (Göpp), and a new genus and species Diplotheca stel- 

 lata were obtained. The latter is a fern fructification allied to 

 Calymmatotheca Stur., but differs in the long linear sporangia 

 being united at the base in pairs. Six pairs of geminate 

 sporangia spread starlike from a common point of attach- 

 ment, giving the fossil much the appearance of a whori of 

 Anmilarla leaves. 



The following are among the more important plants obtai- 

 ned from the Fifeshire Coalfield. Rhacopteris paniciili- 

 fera Stur., lirst British record, Alcicornopteris n. sp., Sphe- 

 nopteris n. sp., Rhodea moravlca (Ett.) and Bothrodeudroii 

 Depereti Vaffier (new to Britain, and discussed here). 



From the Calciferous Sandstone of Cockburns path,. 

 Berwickshire, the three following very rare species are 

 recorded. Sphenopteris siibgeniculata (Stur), Rhodea macha- 

 neki (Ett.), Rhodea patentissima (Ett.). Arber (Cambridge).

 and Distribution. (Presidential Address to the Botanical 

 Section of the British Association. Southport. September 

 1903. Separate Copy. 25 pages. With 2 maps.) 



The author's aim is to illustrate one aspect of palaeobotany 

 which has not received its due share of attention : the geogra- 

 phica! distribution of the floras of the past. 



One difficulty that meets us at the outset in approaching 

 the study of plant distribution is that of synonomy. Endless
