to the Beania type, and it is not improbable that these examples' 

 indicate ancestral features, as CelakoTsky ' has suggested. Without 

 wishing to overstrain such arguments as may be adduced in favour 

 of this view, we prefer to regard Beania gracilis as a female flower, 

 which was more probably borne by a plant belonging to the 

 Ginkgoaceae than by a member of the true Cycadaceae. 



A type of flower similar to Beania has been described by 

 Ifathorst as Zamiostrohus stenoracMs, from the Ehtetic plant-beds- 

 of Scania.''

The main features of the type - specimen are well shown in 

 Carruthers' drawing, but the central axis and the wrinkled seeds- 

 are rather more clearly reproduced in Eig. 11, PL IX.

Genus CZEKANOWSKIA. 



[Heer, Flor. foss. Arct. vol. iv. (2), p. 65, 1877.] 



Heer places the genus CzehanowsMa among the ConifcrEe, and 

 defines it as follows : — 



" Folia numerosa in ramulo abbreviato caduco fasciculate, 

 subulata, rigida, diohotoma, squamis compluribus persistentibus 

 circumdata. Flores feminei racemosi. Fruotus pedunculo brevi 

 insidens, nuoulis duabus valde approximatis." 



The long and naiTOw needle-like leaves, originally placed by 

 Lindley & Hutton ° in the genus Solenites and compared by them 

 with the recent Isoetes, are considered by Heer to belong to 



' Celakovsky (90).
