TIIK MAKVLANI) CYC'ADS. 423 



It is of a (lai'k iron-fcd coloi', well silicilicd, nuKloratoly hai'd, and 

 li(>av\ . The hoijilit aloiifr the lono;est odfjo is '.i'2 cm., hut alons the shortest 

 edo;e it is only 22 cm. At the middle above the ol)li(iue base where 

 widest il lias a breadth of 23 em., indicating a major axis foi- lli(> trunk 

 of 30 oi' 3-') 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: PI. LXXX, near No. 34.) 



PL LXXXIV, Fig. 2, represents (he .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. I9()-H)l of his monogi'aph 

 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 

 featur(> is what seems to be a true branch or secondary axis near the ujiper 

 edge which risers about 3 cm. above the general surface. It is sui'rounded 

 by leaf scars and shows at the (tenter 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 hoi'izontal 

 and 8 cm. and the shorter vei'tical and 5 cm., while the axis, also elli])tical, 

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

 light -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 wei'e arranged in a 

 large group and photograplied 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 inti-o- 

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

 as figures of that plate. Being ari'anged 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 oi'dfM' of the figui'es, and 

 those not elsewhere figured will be described. 



PI. LXXXVn, Fig. 11, 3 represents the Link trunk, W. C, B., Xo. 

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

 described below.
