452 FLORA OF THE CARBONIFEROUS PERIOD-. 



3. L. majus f Brongt. 

 M. C. Sydney, R. Brown. 



4. L. 



Broad ovate, short, pointed, one nerved, half an inch long. 

 Upper coal formation, Pictou. 



5. L. intermedium, L. & H. 

 M. C. Sydney, R. Brown's list. 



Halonia, Lepidostrobus and Lepidophyllum, including only 

 parts of Lepidodendron and Lepidophloios, are to be regarded as- 

 merely provisional genera. 



Lepidophloios, Sternberg. 



Under this genus I include, on the evidence of numerous 

 specimens, those plants kuown under the names Ulodendron, L. <fc 

 H., Bothrodendron, L. & H., and Lomatofloyos, Corda, and in part 

 Halonia, Lepidostrobus and Lepidophyllum. These trees have 

 more or less elevated areoles or leaf-bases, rhombic in outline, and 

 terminated by rhombic scars, bearing long, narrow, one-nerved 

 leaves. The fruit consists of large strobiles borne on the sides 

 of the stem and branches.' The internal structure presents a 

 large cellular pith, a slender cylinder of scalariform vessels, a very 

 thick cellular and corky bark, and a dense rind or epidermis. 

 They appear to have branched seldom and dichotomously, and are 

 nearly related to Lepidodendron. They are abundant in the 

 Middle coal formation . 



1. Lepidophloios Acadianus, s. n. 



M. C. Joggins, Salmon, R., Pictou, J. W. D. ; Sydney, R- 

 Brown. 



Leaf-bases broadly rhombic or in old stems regularly rhombic 

 prominent, ascending, terminated by v§ry broad rhombic scars 

 having a central point, and two lateral obscure points. Outer 

 bark laminated or scaly. Surface of inner bark with single points 

 or depressions. Leaves long, linear, with a strong keel on one side 

 five inches or more in length, cone-scars sparsely scattered on 

 thick branches, either in two rows or spirally, both modes being 

 sometimes seen on the same branch. Scalariform axis scarcely 

 an inch in diameter in a stem five inches thick. Fruit, an ovate 

 strobile with numerous acute scales covering small globular spore 

 cases. This species is closely allied to Ulodendron majus and 

 Lepidophloios laricinum, and presents numerous varieties of 

 marking.
