Baiera leaves from Korumburra, similar in form to those shown in my Figs. 36 
and 37, but of larger size, are figured as Baiera subgracilis, McCoy.* * * § In the 
following list I have made some alterations in nomenclature, which appear to 
me to express the affinities of the Australian types. 
Baiera multifida, Font. 
1888. Salisburia palmata, Ratte. 
1898. Ginkgo Simmondsi, Shirley. 
The leaves described by Ratte and Shirley may be identical with Fontaine’s 
species from North American rhaetic beds.f Mr. ArberJ in a recent paper 
on Australian plants expresses himself in agreement with this opinion.§ 
Baiera bidens, Ten.-Woods. 
A form very similar to Bunbury’s Baiera gracilis\\ from England and 
other European regions. 
Baiera ginkgoales, Shirley. 
B. Ipsviciensis, Shirley.** 
The leaf named by Shirley, Ginkgo phoeniciformis is represented by a frag¬ 
ment too small for determination. 
Baiera subgracilis, McCoy. 
A large type of leaf from Gippsland^f with several fairly broad linear 
segments, comparable with B. bidens , T.-Woods. 
Ginkgo antarctica, Sap. 
1885. Salisburia antarctica , Saporta. 
1888. S. antarctica , Ratte. 
1898. Ginkgo antarctica , Shirley. 
This type is recorded by Shirley from Denmark Hill, Ipswich. 
A fragment figured by Johnston from Tasmania as Salisburia Hobartensis 
may be compared with Baiera Phillipsi, Nath., from the Yorkshire oolite 
rocks, but the specimen on which Johnston founded his species is hardly large 
enough for identification. 
In addition to the leaves referred to above, the fossils described by Shirley 
as Stachyopitys annularioides and S. Simmondsi may be compared with 
Schenk’s rhaetic species Stachyopitys Preslii, and, like the latter type, may 
possibly represent male flowers of one of the Ginkgoales. 
Female Flowers (Ginkgoales) (?). 
Figs. 39, 40. 
The collection includes several fragmentary specimens which are too 
imperfect to identify with any certainty, but it is possible they may be portions 
of a female inflorescence of Ginkgo or Baiera. In one specimen (Fig. 39, 
specimen 188 , allotment 32 a, Kongwak), there is a portion of an axis giving
