This plant is abundant in some layers of shale near Ht John. It resembles , L. and II., but the leaves are longer, loss curved, and more numerous in a whorl. Some of the s|jecimens 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 diminisiiing in size toward the apex. My specimen of this and the following species of Astcrophyllites are from the collections of Messrs Matthew and Ilartt, and were obtained from the ledges and cliffs west of Carlton. I believe the small strobiles, one of which is seen at 11'^ to be the fruit of this species. Fig. 187.â A, AstcropliylUtes Intifolia. D, A. latifolia, larger whorl of leaves. B, Do. apex of stem (?)
