TEIASSIC FLORA OF BALI) HILL. 
The almost perfect leaf-sheath here figured (fig. 16) shows its 
cliaracteristic contracted form. It can be matched with a stem of 
equal diameter in. the National Museum collection, having the whorls 
in position, and which was obtained from the uppermost coal seams 
at Newcastle, New Soutli Wales. 
The figured sjiecimen referred by Dr. Walkoni to this s])ecies, 
from the Ipswich Series (Trias.), of Denmark Hill, Ipswich, Queens- 
land, has more distinctly separate leaves than usual ; their shortness 
and nan'omiess makes them referable to Phi/Uotliem rather than to 
NeAjmkrmiteff, as Walkom has remarked. 
Phyllofheca cmiertma T. Woods, from the Hawkesbury Sandstone 
of Sugarloaf Hill, New South Wales, represents a probable joint with 
indications of leaf-sheaths, and not unlike the specimen here fiyured 
(fig. 16). 
Dmieii'SKms. The leaf-whorl, as preserved in the Bacchus Marsh 
specimens, has a maximum diameter of 26mm., whilst the lieight of 
the whorl, that is, the length of the longest leaves, is 35mm. 
Distribution. Plnjllutheca australis is confined to Australia and 
lasmauia. It is commonest in the Middle and Uj)per Coal Measures 
(Permian) of New South Wales, but is occasionally found in the 
1 riassic. ^ I he Ipswich Series, in (fiieensland, of similar age, contains 
this species, as recorded by Dr. Walkoni ; and there is a sjiecimen 
from Brisbane in the National Museum. Feistmantel recorded 
Phijllotheca australis from the Mersey Coal-field and the Jerusalem 
Basin of Tasmania.^” 
^ The record of Phyllothpea australis in the Progress Kejjort 
(No. III.) of the A ictorian Ceological Surv'ev, p. 60, as occurring 
in the .lurassic of Cape Patterson, a,|)))ears to be open to some doubt. 
The specimen has not been found in the collection of the National 
Museum ; there is, ho-wever, an example from the Albeit River, 
Cippsland. labelled by McCoy as P. australis, but this identification 
seems open to question, as only the denuded stem is seen, with 
traces of joints, and might more justifiably be referred to Equisrtites 
which is not uncommon in those beds. The Cippsland Coal-measures, 
have generally been acTejited as the equivalent of the upper Mesozoic 
of (fiieeiLsland (Walloon Series), but there are a few interesting 
occurrences of exceptional plant species which may, wdth further 
study, jirove the existence of a Triassic flora as w^ell, and wdiich, 
from the already kmnvn evidence, must be the case in Tasmania. 
The w'orking out of the exact succession of floras, in both areas 
is much to be desired. That for Tasmania has already been com- 
menced by Dr. Walkom, wJio has recentlv published a paper ou 
J5ismanian Mesozoic Plants, and the 'writer, in collaboration 
wnth Miss I. (Mokson, hopes shortiv to undertake the descritition 
of the Victorian Mesozoic Flora.
