Although the number of forms, forty in all, is not large, it will 
at once be noted that it embraces representatives of the four domi- 
nant and characteristic groups of the older Gondwana flora, — viz: 
Phyllotheca, Glossopteris, Gangamopteris, and Noeygerathiopsis—all 
of which are present in identical oriental species. In the flora enu- 
merated above the older Gondwana regions of the Eastern Hemis- 
phere are generically or specifically represented by Reinschia austra- 
lis (1) var brasiliensis, Phyllotheca Griesbachi, Phyllotheca Muelleriana, 
Phyllotheca sp., Sphenopteris hastata? Neuropteridium Plantianum, 
Glossopteris Browniana, Glossopteris indica, Glossopteris ampla, 
Glossopteris occidentalis, Glossopteris sp., Vertebraria sp., Gangamo- 
pteris obovata, Arberia minasica, Oftokaria ovalis, and Noeggera- 
thiopsis Hislopi (2). 
The types ‘described under the genera fRosellinites, Derbyelia, 
and Hastimima also while new, are to be regarded as belonging 
to the Southern flora, and will probably be found in other lower 
Gondwana areas. 
The Northern fiora is specifically represented by but two species, 
Lepipophlois laricinus, and Sigillaria Brardii; and, indirectaly, by 
but four species, Lepidodendron Pedroanum, Sigillaria australis, 
Sigillaria (2?) muralis, and Psaronius brasiliensis. 
It will perhaps be found later that Lycopodiopsis Derbyi, the 
Psaronius (3) just mentioned, the types referred to Dadozxylon and the 
species of Cardiocarpon, are in reality characteristic of the Southern 
flora, rather than of a transitional zone of intermingled specics. 
{t is, in fact, probable that the fossil woods, some of the seeds, 
and the Lycopodiopsis are Southern types.

(2) As further proot of the identity of the older Gondwana flora in South America 
mention may be made of the identilication by Professor Kurtz (in Bodenbender, Bol. 
Acad, Nac. Ciencias, Cordoba, vol XVII, 1902, p. 203), from heds af the same series in 
Arventina, of G/lossopterts vetifera, Euryphylliim Whithanwn, Rhipidopsis ginkgoides, 
Lhipidopsis densinervis, Phyliotheca deliquescens. 
(3) The tetrastichous section of Psaronius, represenled by Psaronius brasiliensis 
has not yet been recognized in the Northern flora.
