DESCBIPTION OF SPECIES. 87 



resembled the wood of Pinus Strobus. The absence of foliage, of fruits, and 

 of branches or recognizable markings, seems to indicate that this wood has 

 traveled a long distance in the currents which transported the coarse sedi- 

 ment. All the facts then indicate that while the low grounds and marshes 

 abounded in Ferns and Equiseta, the high and remote grounds were covered 

 with coniferous plants. 



Baiera multifida, spec. nov. 



Plate XLV, Fig. 3; Plate XL VI, Figs. 1-3; Plate XLVII, Figs. 1, 2. 



Leaves narrowed below into a peduncle and divided dichotoinously into numerous 

 lacinise, which are strap-shaped, and in the ultimate divisions narrow and linear ; leaf 

 substance coriaceous, but not very thick, nerves strong, closely placed, forking dicho- 

 tomously at long intervals, parallel to one another and to the margins of the lacini»3. 



There is some variation in the mode of division of the leaves of this 

 plant. Quite a common form is that shown in Plate XLVI, Fig. 1, where 

 the leaves start with a cuneate base and divide first into two segments, 

 which in turn, by repeated division in a dichotomous manner, finally form 

 narrow thong-like lacinise, which are about 3 millimeters wide. These 

 may subdivide again, but I have never seen the lacinise any narrower. The 

 tips of these divisions are wanting in the most complete specimens seen, so 

 that the leaf must have had a length greater than that of the largest speci- 

 men found, or that depicted in Plate XLVI, Fig. 1. This leaf must have 

 had a length of over 25 centimeters, not including the petiole. Plate 

 XLVII, Fig. 2, represents segments of a leaf which must have been even 

 larger. The plant depicted in Plate XLVII, Fig. 1, must have had a great 

 expanse laterally, as well as in length. In Plate XLV, Fig. 3, the mode 

 of division near the base of the leaf is different from that seen in the 

 above-named figures. Here the formation of numerous segments of nearly 

 equal width would give the leaf more of a flabellate shape. The plant is 

 quite abundant at Clover Hill, and is not uncommon at Carbon Hill. 

 Strange to say I have not succeeded, in a single case, in finding the petiole, 

 although I sought for it persistently, and we would expect to find this por- 

 tion more commonly than any other, as its greater thickness and strength 

 would cause it to have a better prospect of preservation than the thinner
