Note 18 — Chapter IV
Reading edition
The fossil given in Fig. 9 is named by Lindley (Foss. Flo. t. 15, 16), Calamites nodosus. He admits, however, that it was not found in actual contact with a calamite stem. It has exactly the contour of an asterophyllite, and might, perhaps, be referred to that genus. It is inserted here that the reader may see the general form of the asterophyllites, and the close relationship that subsists between these plants and the calamites.
