includes examples closely resembling Baiera australis. Tenison-Woods’ 
Ipswich species, Jeanpaulia bidens* * * § represents a type of leaf very similar to 
the Gippsland species. 
Fig. 36 (220, allotment 30, Jumbunna East).—The lamina is not quite 
complete, and the number of segments may have originally exceeded five ; 
the longest segment has a length of 2'3cm., and is 4mm. in breadth. 
Fig. 37 (202, allotment 1, parish of Kongwak).—The lamina is less 
spreading than in the leaf shown in Fig. 36 ; in the broadest segment there 
appear to be nine or ten veins. 
Localities. —Allotment 30, Jumbunna East; allotment 32a, Kongwak. 
Other Specimen. — 29 (Allotment 32a, Kongwak). 
Baiera delicatula, sp. nov. 
Fig. 38. 
Leaf of similar form to Baiera gracilis , Bunb., and B. Muensteriana, Presl, 
but of smaller size. The lamina, which is dissected into numerous narrow 
linear segments, is bisected by a deep median sinus. 
This form of leaf may be conveniently regarded as a type distinct from 
Baiera australis; while agreeing in the numerous narrow segments with 
B. gracilis it can hardly be included under that species. The specimen shown 
in Fig. 38 suggests a leaf of more delicate texture than B. australis ; the slender 
and spreading segments might represent the ultimate divisions of a fern frond 
such as Actinopteris radiata or Schizcea dichotoma.'f 
Fig. 38 (208, Irvine’s Creek, Otway district).—The petiole is l'8cm. in 
length, and the lamina is approximately 3'5cm. broad ; the veins are hardly 
visible. 
Locality. —Irvine’s Creek, Otway district. 
Previous writers have shown that the Ginkgo ales were formerly repre¬ 
sented in the Australian flora. In 1883 Tenison-WoodsJ figured a leaf under 
the name Jeanpaulia bidens from the Burnett Kiver coal, which he placed in 
the Ophioglossaceae. Feistmantel§ included this species, as Baiera bidens , in 
the Taxacese, and Shirley|| adopted the generic name Ginkgo for Tenison- 
Woods’ type, which he compared with Heer’s Ginkgo Sibirica and G. Schmidti- 
ana. In 1888 Ratte described an unusually large leaf-as Jeanpaulia pabnata, 
from the Wianamatta shales, which he speaks of as Triassic ; in a later note 
the same author adopts the generic name Salisburia .If More recently Shirley** 
has recorded additional leaves of the Ginkgo and Baiera type from the Ipswich 
formation of Queensland. The leaf named by Saporta, ^Salisburia antarctica, 
and figured also by Ratte and Shirley,Jt may be added to the list of Australian 
representatives of the Ginkgoales. In Stirling’s Reports of 1892 and 1899
