1494 QUEENSLAND FOSSIL FLORAS 
(c) The Triassic flora. The only series definitely Triassic 
in age in Queensland is the Ipswich Series, whose flora, as at 
present known, comprises some thirty-six species, as 
follows :— 
Equisetites rotiferum Stenopteris elongata 
Equisetites sp. Bennettites (Williamsonia) sp. 
Phyllotheca australis Pterophyllum multilineatum 
Neocalamites hoerensis Tenopteris Tenison-Woodsi 
Neocalamites cf. Carrerei Teniopteris Carruthersi 
Schizoneura ct. africana Teniopteris Dunstani 
Cladophlebis australis Teniopteris lentriculiforme 
Cladophlebis Roylei Teniopteris wianamattee 
Coniopteris delicatula Teniopteris crassinervis 
Dictyophyllum rugosum Ginkgo antarctica 
Thinnfeldia Feistmanteli Ginkgo digitata 
Thinnfeldia lancifolia Ginkgo cf. magnifolia 
Thinnfeldia odontopteroides Baiera Simmondsi 
Thinnfeldia acuta Baiera bidens 
Daneopsis Hughesi Baiera ipsviciensis 
Sagenopteris rhoifolia Baiera ginkgoides 
Sphenopteris lacunosa Stachyopitys annularioides 
Sphenopteris swperba Stachyopitys Simmondsi 
In addition, gymnospermous seeds and coniferous 
woods are abundant. 
The presence of a number of species whose systematic 
position is uncertain makes it inadvisable to state here the 
proportions of the larger plant groups. There may be 
noted, however, a relative abundance of ferns, cycads and 
ginkgos. A remarkable feature is the apparent absence 
of coniferous remains, with the exception of large silicified 
trunks which are probably coniferous, and are of rather 
common occurrence. Forerunners of Mesozoic conifers 
have been found in the Upper Paleozoic rocks in New 
South Wales, but have not yet been found in Queensland. 
The flora of the Ipswich Series shows in general a 
resemblance to floras in various parts of the world, which 
have been regarded as of Rhetic age, and there seems little 
‘doubt that the position of the Ipswich Series in the 
Geological Record may be fixed as Upper Triassic. | 
‘The flora which shows the closest resemblance to the 
Ipswich flora is that of the Stormberg beds in South Africa, 
there being at least nine species which are identical or
