microscopic examination of specimens of Myeloxylon from the 
Millstone Grit of the British Carboniferous. Similar or identical 
wood from other localities have been classed at different times as a 
palm, a fern and a cycad and have been described under the

‘termediate between the ferns and cycads, but most closely allied 
to the latter. re Yay 2
