10. G. divergens, Feist. 
IV. Type of Glossopteris decipiens. Midrib impersistent in the 
upper portion of the frond at a considerable distance from the 
apex. 
Frond narrowly spatulate, truncated at the base. Meshes narrow, 
oblong. 
11. G. decipiens, Feist. 
Frond oblong-oval, petiolate. Meshes broad, oblong. 
12. G. longicaulis, Feist. 
V. Type of Glossopteris orbicularis. Fronds orbicucalar, sube- 
marginate. Meshes broad, oblong-polygonal. 
13. G. orbicularts, Feist. 
To the group of species with elongated leaves, represented by 
Glossopteris stricta in the above synopsis, is to be added the Glos- 
sopteris occidentalis characterized, in addition, by its greatly elon- 
gated leaf with cordate base, acute apex, and Taeniopteroid nervation, 
arched and wide meshes close tothe rachis, but parallel, extremely 
close, and very rarely anastomosing while passing, nearly at a right 
angle, to the margin. 
Glossopteris is the most easily recognized and one of the most 
characteristic types (1) of the older Gondwana or Southern Permo- 
Carboniferous flora, to which Neumayr accordingly gave the name 
“‘Glossopteris flora”. with the exception of Victoria in Auslralia the 
genus is found in all regions (2) where the Gondwana flora is in 
evidence, in Asia, Australia, South Africa, and South America. 
It is also reported by Amalitzky from the Upper Permian of nor- 
thern Russia. As already noted the spore-bearing organs definitely 
correlated with the.leaves of Glossopteris are perhaps nearest related 
to the cycad type of inflorescence. 
Among the many thousands of specimens from different regions 
(1) As has already becn stated, the genus Gangamopteris is equally if not more char- 
racteristic of tropieal flora and is nearly always present; and since it is confined to the 
Jower, or Permo-Carboniferus Palaeozoic , Gondwana flora, it is far more appropiate and 
significant as the special geuus by whieh paleontogica'ly to d signate this flora. Not only 
docs the genus Glossopterts range, mingling with younver t pes, as hich as the Rhztic, 
but it has the furth r disadvantage of having had its name originaliy applied by Brongni- 
art and Sternberg, monotypicaily and with absolute val.dity, to the fussil plant remains, 
now known as Lepidophyllum.
