the apex. The centre from which the leaves radiate has a shining 

 coaly aspect, as if a soft bud or vegetable base of some thickness 

 had been pressed down and carbonized. The same specimen 

 contains a portion of another similar group. 



N'oeggerathiopsis media (Dana), loc. cit., pi. 12, fig. 10. Elon- 

 gate lanceolate, tapering towards the base and broadest within an 

 inch of the apex. Extremity subtriangular, and apex rounded. 

 Veins a little divergent about fifteen to half an inch. One leaf 

 five inches long, about an inch wide within an inch of apex, and a 

 fourth of an inch at base ; another shorter. Newcastle. 



Noeggarathiopsis elongata. — This is a doubtful species which 

 Dana identified with Morris Zeug o phyllites elongatus, but says 

 that it was found at Newcastle, which is clearly an error. He 

 says that it may be identical with Goeppert's i\ r . distans* but 

 that plant grew in clusters, and, moreover, had veins bifurcating 

 in the middle, which does not occur in Morris' fossil. 



Noeggerathiopsis prisca, Eeistmantel (Pal. Flor. Oest. Aust., 

 p. 158, pi. 16, fig. 3). Leaves unknown, leaflets (pinnules) 

 medium-sized, sub-rhomboid, obovate, slightly inequilateral. Nerves 

 close and fine, emerging radiately from a narrow base and forking 

 twice or thrice. 



Greta Creek, N.S.W., under the marine paleozoic fossiliferous 

 strata. 



Cordaites. Unger. 



Stem a simple woody cylinder without medullary rays, but 

 composed of radiating scalariform vessels, encircling a large pith 

 with transverse lamellar partitions. Bark marked with leaf-scars. 

 Leaves simple, sessile, very long, flat, parallel- sided, with broad 

 clasping base, easily disarticulated from the stem, no midrib, but 

 flue parallel neuration. 



These plants are variously placed by different authors. The 

 leaves have certainly the aspect of endogenous plants, but the stem 

 and woody tissure are cryptogamic. Schimper regards them as 

 coniferous. They are characteristic of the Devonian and Carboni- 

 ferous periods.
