1. Remarks on the Coal Plant termed Stigmaria
Published online by Cambridge University Press: 16 March 2015
Extract
The author, after noticing the proofs of Stigmaria being the root of Sigillaria, called attention to the external organs, known formerly as the leaves, and more recently as the rootlets of the former. He stated that in the many examples of stigmaria which he had examined, he had never observed these rootlets articulated to the stem by anything resembling a ball-and-socket joint, considering the appearance which had led to this notion as due to shrinkage and state of preservation.
