REPORT ON JURASSIC PLANTS. 
By Frederick Chapman , A.L.S., &*c., Palaeontologist to the National 
Museum. 
(With three pla'tes.) 
Introductory Remarks. 
Specimens numbered from 129 10 195, collected by Mr. A. E. Kitson, 
F.G.S., are remains of Jurassic plants, which appear to be from a 
slightly different horizon, or at all events, from an area exhibiting a 
different facies from that which yielded the specimens recently dealt with 
by Mr. A. C. Seward, of Cambridge. 1 . The plant-remains are contained 
in an ochreous shaly mudstone, and in many cases are remarkably well 
preserved. The present series is of a highly interesting nature, and 
should considerably advance our knowledge of the distribution of the 
Jurassic flora of Victoria. 
I't may at this point be noted that Tceniopteris spatulata and its 
varieties appear to range through the whole series of beds in Victoria now 
regarded as Jurassic. Other types of plant-remains, however, will 
probably occur at definite horizons, and when sufficient data have been 
accumulated it should be possible to divide the Mesozoic coal-bearing 
series systematically, and thus to correlate the various Jurassic beds in 
different parts of the State. 
One of the most important and abundant species in the present 
collection is Thinnfeldia odontopteroides , Morris sp., here found in 
company with T. Maccoyi, a species lately described by Mr. Seward. 
Coniopteris hymenophylloides , var. australica, Seward, on the other hand, 
is very rare in this series, as are also Sphenopteris ampla, McCoy, and 
Cladophlehis denticulata , var. australis , Morris. 
The remains of Palissya australis , McCoy, are characteristic, and seem 
to be distinctly separable from forms which may be regarded as tropical 
examples of Taxites. A genus and (?) species of new occurrence in 
Victoria, Australia, is Cheirolepis cf. setosus, Phillips, sp. ; a recognised 
member of the Yorkshire Jurassic flora. The slender habit and upturned 
branches of this form are characters which offer a marked contrast to the 
appearance of branches of the Brachyphyllum type. Some of the Gipps- 
land specimens also bear a resemblance to plant-remains which have been 
described from Yhe Trias, Rhsetic and Jurassic beds of Europe under the 
name of Widdringtonites, but the material is not sufficient for deter¬ 
mination.
