THE DEVONIAN PERIOD. 



slightly arcuate, ten to fifteen in a whorl, longer than the internodes. 

 Length of leaves one-half to three-fourths of an inch. This plant 

 is abundant in some layers of shale near St John. It resembles 

 A.foliosa, L. and H., but the leaves are longer, less curved, and more 

 numerous in a whorl. Some of the specimens show that the stem was 

 leafy, as well as the branches ; and I have a specimen, apparently the 

 termination of a main stem, showing the whorls of leaves diminishing 

 in size toward the apex. My specimen of this and the following 

 species of AsterophylUtes are from the collections of Messrs Matthew 

 and Hartt, and were obtained from the ledges and cliffs west of 

 Carlton. I believe the small strobiles, one of which is seen at H^ 

 to be the fruit of this species.

AsterophylUtes latifolia, Dn. (Fig. 187, A, B, D). Stem somewhat 

 slender, with enlarged nodes. Leaves oblong-lanceolate, about thirteen 

 in a whorl, one-nerved, longer than the internodes. Length of leaves 

 varying from one-fourth of an inch, near the ends of branches, to an
