THE FLORA OF THE COAL FORMATION. 483 



2. 0. subcuneata, Buiibury (Fig. 1G6, A). M. C, Sydney (11, 

 Brown). 



DiCTYOPTERIS, Gutb. 



Dlctyopteris obliqua, Bunbury (Fig. 16G, D). M. C, Sydney (R. 

 Brown). 



LoNCHOPTERis, Brongn. 



Lonchopteris tenids, spec. nov. Pinnate or bipinnate ; pinnules 

 contiguous at the base, nearly at right angles to petiole, oblong 

 elongate, obtuse. Network of veins very delicate. Allied to L. 

 Bricii, Brongn., but with smaller, more elongate pinnules and 

 finer veins. I suspect this to be a thick-leaved Pecopferis, showing 

 a coarse cellular reticulation on the upper surface. M. C, Sydney 

 (R. Brown). 



Sphenopteris, Brongn. 



1. Sphenopteris munda, spec. nov. (Fig. 69). Like 8. Duhuis- 

 sonii, Brongn., or S. irregulayns, Sternberg, in habit ; but the pinnides 

 are obovate, decurrent, and few-veined. M. C, Grand Lake and 

 Springhill (C. F. Hartt). 



2. S. hymenophylloicles, Brongn. M. C, Sydney (R. Brown) ; U. 

 C, Joggins (J. W. D.). 



3. S. latior, spec. nov. (Fig. 70). Petiole forking at an obtuse 

 angle, slender, tortuous; divisions bipinnate; plume with broad, 

 rounded, confluent pinnules ; veins twice forked, with sori in the forks 

 of the veins. In habit like S. latifolia, Brongn., S. Newherryi, and *S^. 

 squamosa^ Lesq. M. C, Grand Lake and Springhill (C. F. Hartt) ; 

 U. C, Pictou (J. W. D.). 



4. S. decipiens^ Lesquereux. M. C, Sydney (R. Brown). 



5. S. gracilis^ Brongn. M. C, Joggins. (J. W. D.) ; Grand Lake 

 (C. F. Hartt). 



6. S. artemisicefolia, Brongn. M. C. Grand Lake, Springhill (C. 

 F. Hartt) ; Sydney (R. Brown). 



7. S. Canadensis, spec. nov. (Fig. 71). General aspect like S. 

 Ilceninghausi, but secondary pinnules with a margined petiole, and 

 oblong pinnules divided into three to five obtuse points. It is not 

 unlike S. marginata, from the Devonian of St. John. Bay de Chalcur 

 (Logan); Sydney? (R. Brown). 



8. S. Lesquereuxii, Newberry. M. C, Sydney (R. Brown). 



9. S. microloba, Guttbicr. M. C, Sydney (R. Brown). 



10. S. obtusiloba {?), Brongn. M. C, Bay dc Chalcur (Logan).
