NOTE ON THE WALLOON JURASSIC FLORA REID. 169 



characteristic amongst others : — Tceniopteris Tenison- 

 Woodsi, T. Dunstani, the large-leaved T. Carruthersi, T. 

 Icnirkuliformc, and T. Wiananiattce : also CladopMebis 

 australis. 



In the Walloon of ]Moreton district, Cladophlebis 

 australis and, to a less degree, Taniopteris spatidata are the 

 predominant species. This holds good through a vertical 

 section of strata probably 5,000 feet thick in the area lying 

 between Marburg and Wilson's Peak. Both are recorded 

 from Darling Downs and from Roma. 



An important feature, however, is that no undoubted 

 species of Thinnfcldia nor any of the Trrniopiendcv, except 

 T. spatulata, were found in the Walloons of the Moretou 

 district, nor during the detailed survey of Rosewood, where 

 fossilferous beds are abundant, and where an intensive 

 search for fossil evidence may be claimed to have been, 

 made. 



Dr. Jensen has informed me that C australis is the 

 most abundant form in the Walloon at Roma, and that no 

 species of Thinnfeldia, nor of Taniiopteris, other than T. 

 spatulata were found in those beds. Thinnfeldia 

 odontopteroides is, however, found there in Ipswich Beds 

 underlying barren sandstones below the Walloon, but not 

 associated with the Walloon plants. Walkom likewise does 

 not record Thinnfeldia, and of the To'nioptcridce only T. 

 spatulata, from the Walloon of South-east Queensland, 

 Darling Downs, and Roma.^ 



The only record of Thinnfeldia in the Walloon of 

 IMoreton District is T. odontopteroides var. falcata, from 

 Rosew^ood Scrub, 10 miles from Ipswich, identified by 

 Tenison-Woods^ and included in the synonymy of T, 

 lancifoliii by Walkom.*^ A provisional determination by 

 Tenison-Woods" of a specimen as GleicJienia li)ieata from 

 the same locality is regarded by Walkom as a doubtful 

 synonym of T. acuta, but this can be disregarded owing to 

 the degree of doubt as to its identity. I can only assert 

 that during the detailed survey of the Rosewood coalfield,
