THE FLORA OF THE COAL FORMATION. 479 



7. C. Nova-Scotica, spec. nov. M. C, Joggins (J. W. D.). Ribs 

 equal, less than a line wide, striated longitudinally. Joints obscurely 

 marked, and with circular areoles separated by the breadth of three to 

 four ribs. Bark of moderate thickness. 



8. C. nodosKs, Schloth. (Fig. 163, C). This species has long slender 

 branchlets, with close whorls of short rigid leaves. M. C, Sydney 

 (R. Brown) ; Grand Lake (C. F. Hartt). 



9. C. arenaceus (?), Jjiger. This species is mentioned with doubt 

 in Lyell's list. 



Equisetites, Stembei'g. 

 Equisetites curta, spec. nov. (Fig. 164). 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. M. C, Sydney (R. Brown). 



ASTEROPHYLLITES, BrongU. 



1. Asterophjlliies foUosa, L. and H. M. C, Joggins (J. W. D.) ; 

 Sydney (R. Brown). Springhill [C. F. Hartt). 



2. A. grandis^ Sternberg (?). The specimens resemble this species, 

 but are not certainly the same. Logan's specimens have terminal 

 spikes of fructification. M. C, Grand Lake (C. F. Hartt) ; Bay de 

 Chaleur (Logan) ; Sydney (Bunbury). Springhill (C. F. Hartt). 



3. Aster ophyllites^ sp. 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 specimen from Mr Brown similar to A. tuberculatum Sternberg, 

 which may be the same. 



4. A. triiiervis, spec. nov. (Fig. 165, A). Main stem smooth, 

 delicately striate, with leaves at the nodes. Bi'anchcs delicately 

 striate, with numerous whorls of linear nearly straight leaves, 0*5 inch 

 long, twenty or more in a whorl, and showing two lateral nerves in 

 addition to the median nerve. M. C, Sydney (R. Brown). 



5. Asterophyllites [Bechera] curta, spec. nov. Stems thin, coarsely 

 ribbed. Internodes about a line long. Nodes with whorls of short 

 linear leaves, nearly at right angles to the stem, which bifurcates at 

 very obtuse angles. M. C, Pictou (.J. Barnes, Esq.) This peculiar 

 species is of the type of A. grandis, and belongs to the section Bechera 

 of Sternberg; plants which, at least in habit of growth, are certainly 

 different from ordinary Asterophyllites. 



Annularia, Sternberg. 

 1. xinmdaria sphenophylloides, Zenker (Fig. 165, B). M. C,
