146 ON THE FOSSIL FLORA OF THE COAL DEPOSITS OF AUSTRALIA, 



1876 ; Geyler, Jura Pflanzen aus Japan, 1877 ; Feistmantel Flora 

 of the Jabulpur group, Upper Gondwanas, Pal. India, vol. 2, p. 

 11 (91), pi. 3, fig. 7 to 14, pi. 4, fig. 1 to 10. 



Leaves remote, deciduous, entire, narrowed at base, lanceolate 

 acuminate at the apex, nerves many, forked just above the base 

 then simple and converging to the apex. Dr. Feistmantel adds 

 that this is " a very characteristic form widely spread in the 

 Jurassic formation. It is known from Spitzbergen, England, S. 

 Russia, East Siberia, Amur, and Japan. In our own Jabulpur 

 group, it is pretty frequent." To these localities I am enabled to 

 add Australia. I have found it very abundantly at Ipswich. In 

 the work already quoted by Dr. Heer on the Jurassic Flora of 

 Eastern Siberia, he distinguishes a number of varieties, some of 

 which were formerly regarded as distinct species. Thus P. distans 

 of Presl., a Rhastic fossil is connected with P. lanceolatus, as well 

 as P. eichwaldi of Schimper. Dr. Feistmantel finds three varie- 

 ties in India, namely, P. lanceolatus genuinus, in which the leaves 

 are lanceolate with a pretty acuminate apex. South Rewab, 

 Jabulpur, and Sher River. P. Ian. var. spathulatus, Feistm., pi. 

 4, fig. 11-12. Leaves shorter, oval lanceolate, base attenuate. 

 "There are some leaves which I think however belong to the same 

 species, distinguishing it as a variety only." South Rewah. 



Both these varieties occur abundantly in the Ipswich basin, 

 one specimen showing how the leaves were affixed to the 

 parent stem, and though the fragment is imperfect it shows pre- 

 cisely the growth figured by Schimper. (Atlas, pi. 71, fig. 1.) 

 There are other fragments of stems which also show the mode of 

 attachment attributed to this species. I am aware of course of 

 the risk of error in making the identification between the fossils of 

 Ipswich and those of Europe, but the resemblance is so close that 

 I do not think that there is any ground for hesitation. 



In the Queensland specimens the veins are simple, straight, 

 parallel, from 8 to 12 in a leaf. Length of leaves from 45 

 to lOOmillim., breadth from 2 to 12 according as the leaf is ovate 

 or lanceolate.
