From the structure of some fossil woods in the New Zealand Survey collection which 
are believed to have been derived from this locality it would appear that this fossil 
forest is composed chiefly of trees having the' Araucarian type of structure. These 
woods are not described here, however, as the records of the locality from which 
they were obtained are uncertain. They appear, however, to be similar to Arau- 
carioxylon australe Crie(l). There is also, I think, little or no doubt that the 
Osmundaceous stems described by Crie(2), and more recently by Kidston and Gwynne- 
Vaughan(3), which were recorded as having been obtained at Toitoi and at Gore 
were really derived from the neighbourhood of Curio Bay, Waikawa(4). 
The Collections. —This locality is one of the richest in plant-remains known in 
New Zealand, so far as the Mesophytic floras are concerned. I have examined a 
large series of specimens, collected by Hector in 1878 and by Park in 1886, belonging 
to the New Zealand Geological Survey collection. 
Previous Records. —With the exception of various nomina nuda mentioned by 
Hector(5) and others, the following are the only species hitherto figured from Waikawa. 
They were published by Hector(6) in 1886 
Hector’s Name. Modern Name. 
Taxites manawao Hect. .. — Elatocladus tenuifolia (McCoy). 
Pecopteris grandis Hect. . . = Cladophlebis australis (Morr.). 
Asplenites palceopteris Unger .. = Coniopteris hymenophylloides (Brongn.). 
Park(7) says that Macrotceniopteris lata, and Tceniopteris stipulata, as well as 
Pecopteris, Asplenites, Taxites, Lomarites, and Camptopteris also occur. 
In 1907 Kidston and Gwynne-Vaughan (3) described the petrified stems of 
Osmundites Dunlopi K. & G.-V. and 0. Gihhiana K. & G.-V., which, as mentioned 
above, were no doubt derived from this locality. 
Conclusions as to the Age of the Beds. —The following is a list of the records 
from Waikawa :—- 
Fern-like Plants— 
Osmundites Dunlopi K. & G.-V. 
O. Gihhiana K. & G.-V. 
Cladophlebis australis (Morr.). 
Coniopteris hymenophylloides (Brongn.). 
Thinnfeldia Feistmanteli (Goth.). 
Tceniopteris vittata Brongn. 
Cycadophyta— 
Cycadites sp. 
Ptilophyllum acutifolium Morr. 
P. sp. 
P ODOZAMITE M~ 
Podozamites gracilis sp. nov. 
CoNIFERALES— 
Elatocladus conferta (0. & M.). 
E. sp. 
There can be no doubt, I imagine, that this flora is of Jurassic age, but the 
question as to the division of the Jurassic to which it should be assigned is of a more

published in the Annals of Botany, 1914, which contains a discussion on specimens of 
Osmundites from Waikawa, and also from Kawhia, North Island.
