336 GEOLOGICAL SURVEY OF THE TERRITORIES. 



In this one, the leaves closely appressed to the stem, either imbricated 

 or distant, two millimeters long, one millimeter broad in the broadest 

 part above the middle, have an oblong, elongated rhomboidal form, with 

 a short, acute point, and gradually taper from above the middle to the 

 decurrent base. In other specimens they are, as in fig. 7, linear, acu- 

 minate, or subulate, four to five millimeters long, less than One millimeter 

 broad, decurring at the base, more generally half open and straight, 

 sometimes, however, slightly falcate. Passing downward upon the 

 same branches, these leaves become shorter, more closely appressed to 

 the stem, the point only being turned outside, and they then are similar 

 to those of the enlarged fig. 5, differing merely by the size. A num- 

 ber of fragments of cones, also, one of them preserved nearly whole, 

 and still attached to a branch, prove that fig. 6 represents rather an 

 unopened young fruiting catkin of the same species than a male one, 

 as I supposed at first. The ripe cone is fourteen millimeters long, five 

 millimeters broad, cylindrical-oval, with scales deeply impressed into 

 the stone, and the apophyses three to four millimeters broad and nearly 

 as long, rhomboidal in outline, acutely narrowed ou both sides, bearing 

 in the middle or a little above a pointed (?) mammilla, marked by a small 

 hole in the stone. Another cone, cut in its length exposes the thick, 

 smooth (not crumpled) foliaceous appendages, and the receptacles of 

 the seeds, which are large and similar to those of the cone described in 

 Cret. Flora, Tab. I, Fig. 10 and 10 b , as Sequoia reichenbacM. Indeed, 

 the form of the opened cone is the same ; this last one appears only some- 

 what longer. All the fragments representing this species are, like the 

 cones, deeply impressed or molded into the stone, even the leaves, 

 which often penetrate it by their points. They appear thus of a thick 

 coriaceous consistence. Their outside surface is, of course, the only 

 part whose impression is represented. It is half-round or slightly chan- 

 neled; the inside surface, if exposed, could perhaps show a middle nerve. 

 This species is distantly related to Sequoia fa stigia.t a, Sternb.," described 

 above, differing by the pinnate mode of division of the branches, the 

 form of the leaves, etc. The fragment, fig. 7, has a likeness to the one 

 represented by Heer in his Flor. Fobs. Arct.HI, PI. XXVII, fig. 9°, as 

 Sequoia rigida, a species, however, far different by the visible nerve of 

 its leaves and by the large size of its cones.

Leaves by jive, very long and, slender, linear, deeply nerved, the base in- 

 closed in o, long cylindrical sheath; cones cylindrical, very long, scales with a 

 broadly rhomboidal shield (apophyse) acute on the sides, mammillate in the 

 center. 



The specimens representing this species are numerous, but all 

 more or less fragmentary. The attachment of the base of the leaves by 

 five is more or less distinctly marked by the long sheaths forming deep 

 holes into the stone, the orifice of which has remains of leaves; these 

 are very numerous, always seen by their deep impressions, half cylin- 

 drical on the back, channeled and deeply nerved on the inside, as 

 marked in the enlarged figure 7 a . The length of these leaves is not rec- 

 ognizable from our specimens, which have mere fragments, five to eight 

 centimeters long; but Prof. Heer, who had complete splendid speci- 

 mens for his description, gives the measure at twenty centimeters; 

 their width being scarcely one millimeter. The cylindrical cone is
