THE MARYLAND CYCADS. 423 



It is of a dark iron-red color, well silicified, moderately hard, and 

 heav.y. The height along the longest edge is 32 cm., but along the shortest 

 edge it is only 22 cm. At the middle above the oblique base where 

 widest it has a breadth of 23 cm., indicating a major axis for the trunk 

 of 30 or 35 cm. The minor axis at the base, one side of the center to 

 miss the fracture, is 18 cm. Measured over the circumference, 43 cm. 

 are found to be preserved here. The radial thickness below is 12 cm., and 

 9 cm. at the summit. (Locality: PL LXXX, near No. 34.) 



PI. LXXXIV, Fig. 2, represents the Johns Hopkins University 

 cycad No. 3 in a much better position than it was shown in the view 

 sent by Tyson to Mr. Meek (see PI. LXXXIII, Fig. 2). This specimen 

 was described by Professor Fontaine on pp. 190-191 of his monograph 

 as "Fragment No. 1," but not figured. It is a segment from the side of 

 a trunk that has suffered from vertical compression. Its only remarkable 

 feature is what seems to be a true branch or secondary axis near the upper 

 edge which rises about 3 cm. above the general surface. It is surrounded 

 by leaf scars and shows at the center a well-defined axis, apparently 

 vascular, with very small tubes irregularly scattered through it. The 

 branch is elliptical in cross section, the longer diameter being horizontal 

 and 8 cm. and the shorter vertical and 5 cm., while the axis, also elliptical, 

 is 20 mm. by 10 mm. thick. The fragment is soft and friable and of a 

 hght-ash color, pure white within, as shown where freshly broken or 

 bruised, appearing as if calcareous. (Locality: PI. LXXX, near No. 129.) 



Most of the specimens at the Woman's College were arranged in a 

 large group and photographed in 1900. This group includes, besides all 

 the principal types, a large number of less important specimens and 

 small fragments that are not otherwise illustrated. The view is intro- 

 duced here as PI. LXXXVII, and the specimens included in it are treated 

 as figures of that plate. Being arranged in tiers it has been found con- 

 venient in finding the figures to number the tiers in Roman from below 

 upward, I-V, and the figures from left to right on each tier in Arabic. 

 Seventeen of the figures of this group represent specimens referred to 

 C. marylandica. These will be taken up in the order of the figures, and 

 those not elsewhere figured will be described. 



PL LXXXVII, Fig. 11, 3 represents the Link trunk, W. C, B., No. 

 1481, whose history has already been given and which will be fully 

 described below.
