440 FLORA OP THE CARBONIFEROUS PERIOD. 



6 G. dubius, Artis. 



M. 0. Sydney, R. Brown ; Joggins, J. W. D., Logan ; U. O 

 Piclou, J. W. D. 



7. O. Nova Scotica, s. n. 

 M. C. Joggins, J. W. D. 



Ribs equal, less than a- line wide, striate longitudinally. Joints 

 obscurely marked and with circular areoles separated by the 

 breadth of 3 to 4 ribs. Bark of moderate thickness. 



8. C nodosus, Schlot. 



M. C. Sydney, R. Brown : Grand Lake, C. F. Hartt. 

 This species has long slender branchlets, with close whorls of 

 short rigid leaves. 



9. C. arenaceous ? Jaeger. 



This species is mentioned with doubt in Lyell's list. 

 Equisetites, Sternberg.. 



Equisetites curta, s. n„ 



M. C. Sydney, R. Brown. 



Short thick stems, enlarging upward and truncate above, joints 

 numerous, sheaths as long as the joints, with unequal acuminate 

 keeled points. Lateral branches or fruit with longer leaf-like 

 points. Has the characters of Equisetites, but its affinities are 

 quite uncertain. 



ASTEROPHYLLTTES, Brongt. 



1. Asterophyllites foliosa,L. and H. 



M. C. Joggins, J. W. D ; Sydney, R. Brown. 



2. A. equisetiformis, L. and H. 



M. C. Sydney, R. Brown ; Pictou, J. W. D. 



3. A. grandis, Sternberg. 



M. C. Grand Lake, C. F. Hartt ; Bay de Chaleur, Logan ; Sydney^ 

 Bunbury. 



The specimens resemble this species, but are not certainly the 

 same. Logan's specimens have terminal spikes of fructification. 



4. A. 



A species with tubercles (fruit) in the axils is mentioned in 

 Lyell's list as from Sydney. I have not seen it, but have a speci- 

 men from Mr. Brown similar to A. tuberculata, Sternberg, which 

 may be the same. 



5. A. trinervis, s. n. 



M. C. Sydney, R. Brown. 



Main stem smooth, delicately striate, with leaves a t the nodes 

 Branches delicately striate, with numerous whorls of linear nearly
