AUTHOR'S PREFACE. 



The present contribution completes the examination of that 

 ^section of the Mesozoic fossil plants forming the flora of the Ipswich 

 and Walloon Series. A few specimens still remain undescribed ; 

 some of these have been obtained after the completion of the section 

 of the work dealing with them, and the description of others has 

 for various reasons been delayed, and it is hoped that at some 

 future date these will be described with any further specimens 

 which may be obtained. 



In my account of Tceniopteris given in Publication 257 of the 

 Queensland Geological Survey, reference was omitted to some 

 remarks on the Victorian species by Mr. F. Chapman in a Report on 

 Jurassic Plants published in the Records of the Geological Survey of 

 Victoria (vol. 2, pt. 4, p. 215). Chapman there regards T. spatulata, 

 McClelland, as a central t;ype, variations in two directions ranging 

 to the form known as T. Dainireei on the one hand and T. Carruthersi 

 on the other. To these two he gives varietal names T. SjMtulata 

 var. Carruthersi and T. spatulata var. Daintreei. 



As the result of my examination of the Queensland collections^ 

 I unite T. Daintreei with T. spatulata, and regard T. Carruthersi 

 as a distinct species. The latter species occurs in the Ipswich 

 Series and only occasionally in the Walloon Series, while T. spatulata 

 {—T. Daintreei) does not occur in the Ipswich Series, but only in 

 the Walloon Series. 



The example figured by Chapman from Park Cutting, near 

 Brisbane, as T. spatulata, McClelland,- shows the secondary veins 

 making an acute angle with the midrib and appears to be referable 

 to T. Tenison-Woodsi.
