Description:Excerpt from Proceedings of the Biological Society of Washington, Vol. 11: March 13, 1897 A year ago I had proceeded far enough to have discovered that the cycadean trunks from the Iron Ore beds of Maryland embraced no less than seven good species which could be clearly separated and described, and since that time I have accomplished the work of describing and naming these species and of assign ing each specimen to its appropriate specific group. As it is very convenient in the general discussion to be able to speak of these forms in a definite way, I have decided to publish these names with the descriptions, so that the new species may not need to be mentioned prior to such description, thereby cum bering the literature with nomina nuda. It is, however, clearly to be understood that these descriptions are not final, as they are based entire] y on external characters and such macroscopic observations as I have been able to make of the internal parts prior, for the most part, to the cutting of sections, and do not embody anv results that may be arrived at by Dr. Knowlton after a microscopic study of the various tissues. This latter, however, can scarcely result in reducing the number of species, as the more general characters are those that have been chiefl y relied upon for Specific differentiation, and if it results in increas ing the number by showing that some of the specimens possess internal characters that cannot be specificallv united with the others, this will lead to no confusion.
