Fossil Floras of Cape Colony. 69 



suggests a comparison witli the genus Podozamites, but this occurs 

 in association with gradually tapered leaves like that I'epresented 

 in fig. 9, and the difference in the method of termination is in 

 itself hardly a sufficient reason for the separation of the two 

 forms. 



With the exception of the forked vein shown in fig. 10, pi. ix., near 

 the apex of the specimen, I have not detected any certain indication 

 of the parallel veins in these leaf fragments from Cyphergat and 

 Molteno ; in Nrnggcrathiopsis leaves of similar form to that shown in 

 pi. ix. figured by Feistmantel,''' Zeiller,! and other authors the veins 

 are dichotomously branched in their course through the lamina, and I 

 have no hesitation in expressing the opinion that the African specimens 

 should not be referred to that genus. Kurtz \ has recently expressed 

 a similar opinion as to the difference lietween the true Noaggerathiopsis 

 and Morris's Zcugophyllites clongatus. 



Mr. x\rber § has also drawn attention to a confusion between Noegger- 

 athiopsis and Zcugoplvjllites. 



Plate IX., fig. 1 (C). 



An imperfect leaf 16 cm. long, and with an approximately uniform 

 breadth of 1'2 cm. The lamina between the fairly broad veins is 

 finely striated, the stri» no doubt representing hypodermal strands 

 of mechanical tissue. 



Plate IX., fig. 9 (d). 



The figure represents the gradually tapered (basal ?) end of an 

 incomplete leaf 10.5 cm. long. 



Plate IX., fig 10 (69). 



The blunt apex of a leaf from Molteno showing the converging 

 terminations of the veins. The venation is less clearly seen 

 in this specimen than in the other figured pieces. Acuminately 

 pointed leaves similar to the specimen from Cyphergat represented 

 in fig. 9 occur on the same piece of rock.
