In Mr. Bibbin's contribution to the Original Sources of the Maryland 

 Cycads, and in the chapter on their Folklore compiled by Miss Hopkins 

 from the data collected by him, it was found advantageous to introduce 

 illustrations of most of these historic specimens. These illustrations 

 will be enumerated here, along with such additional ones as it has seemed 

 necessary to introduce. 



PL LXXXI represents the Johns Hopkins cycad No. 1, as photo- 

 graphed by Tyson along with a quantity of silicified wood, and is a repro- 

 duction of the view sent by him to Doctor Newberry and found among his 

 effects by Doctor HoUick. The circumstances, so far as known to me, 

 are described in the historical part of this paper (p. 414). The speci- 

 men was inclined away from the camera so as to show the base. It is a 

 fine and nearly perfect trunk, more or less conical in shape, but somewhat 

 elhptical in cross section, perhaps from lateral compression. It tapers 

 both ways, but only slightly downward. At the summit it is much, 

 smaller, rounding off more rapidly on one side than on the other, as shown 

 in Professor Fontaine's pi. clxxix, Monogr. U. S. Geol. Surv., Vol. XV. 

 The axis is seen to fairly good advantage from the base. At the summit 

 there is a cavity or "crow's nest" 14 cm. across, with a somewhat definite 

 rim, succeeded by a nearly flat depression marked very clearly by small 

 scars of polygonal shape or nearly circular. These average about 6 mm. 

 in diameter. Some of those at the outer margin are subrhombic, and 

 evidently represent small leaves or bracts. The inner polygonal ones 

 may represent floral organs. The material with which they are filled 

 is marked at the summit by somewhat definite pits or scars, as of special 

 organs. The center of this apical depression is occupied by a terminal 

 bud 5 cm. in diameter and 13 mm. high. It is irregularly covered with
