Mr. Binney, F.R.S. : After the researches of Lindley, 
Geoppert, Brongniart, Prestwich, Hooker, and others, it 
really seemed that we had obtained almost a complete 
knowledge of the internal structure of Stigmaria. It is true 
that only Geoppert had seen the isolated bundles in the 
pith, all the specimens of the other observers having been 
imperfect in that portion of the plant, and giving no indica- 
tion of structure there. In my own researches I have rarely 
met with a Stigmaria shewing any structure in the central 
axis, even where the small stems of Sigillaria vascularis 
displaying all the structure in that part are found in great 
abundance. 
Many years since, after the examination of a great number 
of specimens of Stigmaria in my collection, it occurred to me 
that an outer as well as an inner radiating cylinder would be 
discovered. In my remarks on Sigillaria , published in
