extended to form a monograph of the Jurassic plants of Scotland. 

 The detaiied descriptions of species cover the Ferns and Gj^mno- 

 sperms of what is called the Culgower flora. The Kimeridgian age 

 of the leeds from which these plants were obtained is determined 

 from palaeozoological evidence. The Culgower flora is described as 

 having many features in common with the Upper Jurassic 

 i'Wealdenj of Spitzbergen, the English and German Weal- 

 den, as well as with the older Jurassic flora of East Yorkshire. 

 The following species are particularly dealt with: Sagenopteris Phil- 

 lipsi (Brongn.), Ham^inannia dicJiotoma Dunk., H. Buchii (Andrae), 

 H. Richteri sp. nov., Laccopteris Dunkeri Schenk, Matonidium goep- 

 perti (Ett.), Gleichenitis Boodlei sp. nov., G. cycadina (Schenk), Coni- 

 opteris hymenophylloides (Brongn.), C. argiita (L. & H.), C. qiänque- 

 loba (Phillips), Todites Wä/iamsoHt (Brongn.), Cladophlebis denticulata 

 (Brongn.), Marattiopsis Boiveri sp. nov., Rhisornoptei'is Gwini sp. nov., 

 Sphenopteris onychiopsoides sp. nov., Taeniopteris sp., Thinnfeldia 

 yhomboidalis Ett., T. arctica (Heer., T. de Geeri (Nath.), Dichopteris 

 Ponielii (Sap.), Ginkgo Sibirien Heer.), Baiera Braiiniann (Dunker), 

 B. Lindleyana (Schimper), Czekanowskin Mtirrayatta (L. &H.), Phoe- 

 iiicopsis Gitinii sp. nov., Araiicarites Milleri sp. nov., Armicnn'oxyloji 

 sp., Brachyphyllum sp., Elatides atrvifolia (Dunk.), E. Sternbergiana 

 (Schenk), Mascidostrobiis Zeilleri gen. et sp. nov., Taxites Seffreyi 

 sp. nov., Sphenolepidium sp, Coniferocaulon colymbeaefonne Fliehe, 

 Piiiites sp., Williamsonia pecten (Phillips), Pseiidoctenis eathiensis 

 (Richards) gen. nov., P. crassiuervis gen. et sp. nov., Zamitis Bu- 

 chiaims (Ett.), Z. Carnithersi Sew. , Pterophylluni Nathorsti {Seward) , 

 Nilssonia orieiüalis Heer., N. brevis Brongn, N. mediana (Leck.), 

 Bucklajidia MiUeriana Carr. , Otozaniites sp., Cycadospadix Pasinia- 

 nus Zingo. The author remarks on the many points of botanical 

 interest and importance which the Marcus Gunn collection affords, 

 and concludes hy noting the striking changes in geographical distri- 

 bution of several of the generic types. M. C. Stopes. 



Stopes, M. C, Furt her Observationes on the Fossil Flo- 

 wer, Cretovariuni. (Annais Bot XXIV. p. 679—681. 2 pls. 1910.) 



The paper records the discover}^ of and shortly describes ovules 

 in an ovary of Cretovarinm japonicum Stopes and Fujii, and illu- 

 strates also the details of the structure of the ovar}'' wall.

Stopes, M. C The Internal. Anatomv of Nilssonia orien- 

 talis. (Annais Bot. XXIV. p. 389—393. 1 pl. 1910.) 



The plant Nilssonia orientalis Heer had hitherto been known 

 only from leaf impressions from the Mesozoic deposits. Among the 

 nodules from the Japanese Cretaceous which include petrified plants, 

 a broken fragment revealed both the external features of a leaf, 

 which allowed of its Identification with N. orientalis, and also 

 enough of the same leaf embedded so as to allow a series of 

 sections to be cut to show its internal anatomy. The details of the 

 leaf anatomy are described, and they show that the structure was 

 of a simple cycadean type. M. C. Stopes.
