One day in the summer of 1904 a broken Lepidostrobus petrified nicely by iron pyrites was sent to me by Mr. Samuel Spear, then residing four miles south of Indianola. Each year the specimen was exhibited to the class in Geology when Carboniferous plants were illustrated and the explanation given that it was a remarkably rare and choice specimen of a cone, the like of which I had never seen in any museum; but the real value of the specimen was not fully appreciated till I handed the specimen to Professor Stuart Weller at The University of Chicago in December, 1910. I had taken it with me that day, intending to carry it over to Professor Coulter for further information with reference to it. On seeing it, Professor Weller exclaimed that it was the very kind of a specimen that Professor Coulter had been seeking for years, no petrified Lepidostrobus having ever been reported in the United States. On Professor Coulter's request to section the specimen and describe it he was given full permission to do whatever was necessary to secure from it all the information possible. As the result of that work upon it we now have the splendid description and illustrations published by Professor Coulter and Dr. Land in the Botanical Gazette, Vol. 51, June, 1911.
