FLORA OF THE CARBONIFEROUS PERIOD. 439 



'¥■■ 



5. T. {minus, s. n. 



M. C. Joggins, J. W. D. Half the size of T. Hookeri, and sim- 

 ilar in form. 



6. T. rotundum, s. n. 



M. C. Joggins, J. W. D. Small, round ovate, slightly pointed. 



7. T. JVceggerathi, Brongt. 



Newer coal formation, Pictou, J. W. D. 



The Trigonocarpa are very abundant in some beds of the Mid- 

 dle coal formation. Most of them are fruits of Sigillarice, some 

 of them perhaps of conifers. 



Rhabdocarpus, Goep. and Berg. 



1. Rhabdocarpus s. n. 



M. C. Joggins, J. W. D. Ovate, acuminate, less than half an 

 inch long. 



2. R. insignis, s. n. 



U. C. Pictou, J. W. D. ; 1*5 inch long, ovate, smooth, with about 

 *I ribs on one side, and the intervening surface obscurely striate. 

 The nature of this fossil is perhaps doubtful, but if a fruit it is the 

 largest I have seen in the coal formation. 



Calamites, Suckow. 



1. Calamites Suckowii, Brongt. 



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

 Lake, C. F. Hartt. U. C. Pictou, J. W. D. Coal Creek, C. B. 

 Matthew. 



This species is one of the most common in an erect position. 

 It has verticillate branchlets with pinnate linear leaflets. .

 apparently one-nerved and 3 inches long.

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



4. C. ramosus, Artis.
