438 MESOZOIC FLORAS OF UNITED STATES. 



merit resembling W. C, B., No. 1659, and stained the same color as that, 

 but in a bad state of preservation. The form of the scars can not be 

 determined. There is also a transverse fracture, which renders the 

 vertical thickness uncertain. A little over half of the trunk is present, 

 the irregular longitudinal tangential fracture passing one side of the 

 middle. The diameter is 19 cm., the radial distance at right angles to 

 this 11 cm., and the present vertical thickness 7 cm. (Locality: PI. 

 LXXX, No. 106.) 



PI. LXXXIX, Fig. in, 4, shows the outer surface of the Travers 

 fragment. No. 2, M. G. S.-W. C, B., No. 9060, a small, much worn piece 

 of the armor of a trunk of unknown size, of dark color and low specific 

 gravity. This small area, however, 9 cm. by 11 cm., shows very clearly 

 both leaf scars and reproductive organs. It is simply a piece of bark, 

 convex on the outer and concave on the inner surface, and 3 cm. to 4 cm. 

 thick. (LocaUty : PL LXXX, No. 69.) 



PI. LXXXIX, Fig. Ill, 9, gives a view of the outer surface of the 

 Marlowe fragment, No.l, M. G. S.-W. C, B., No. 9055, which is a rather 

 large piece from the side of a trunk, probabl}^ at the base, bounded by 

 two longitudinal radial fractures and one transverse fracture, and extend- 

 ing to the middle of the medulla. The surface is well preserved, and the 

 fractures show the internal structure. It is 15 cm. long, 12 cm. wide 

 above, and 8 cm. below, and 9 cm. thick. (Locahty: PI. LXXX, 

 No. 100.) 



PI. LXXXIX, Fig. Ill, 10, shows the broad side of the R. T. Don- 

 aldson fragment. No. 11, M. G. S.-W. C, B., No. 9054, a light-reddish 

 stained fragment, probably from near the base of a trunk, showing 

 much worn scars on the convex outer surface and the bases of the strands 

 on the concave inner surface. It is 16 cm. long (high), 12 cm. wide 

 (tangentially), and 6 cm. thick, probably including the outer ring of 

 wood. (Locality: PI. LXXX, No. 106.) 



PI. XCIV, from a fine platinum print made by Mr. Smillie, shows 

 as clearly as a picture can show the leading characters of the species as 

 embodied in the next most perfect specimen, W.C., B., Nos. 1659 and 1659a, 

 which were simply broken apart but fit each other perfectly. The view 

 is from the base, but, as in the specimen last described, the leaf scars 

 are shown only below the equatorial zone. The two pieces constitute
