TAXITES, Brgt. 

 Taxites Olriki?, Heer. 

 Plate L, Figs. 6, 6a. 

 Heer, "PL Arct.," i, p. 95, pi. i, figs. 21-24c; xlv, fig. 1 a, b, c. 



Branches slender; leaves distichous, linear-lanceolate, blunt at the apex, rounded 

 and narrowed at the base, sessile. 



The leaves are sessile, not decurrent at the narrowed base, and 

 therefore not referable to the genus Sequoia. Those I have seen average 

 23 millimeters long by 3£ millimeters broad, the same length as indicated 

 by Heer, only slightly narrower; they are more or less curved backward, 

 have a deep medial nerve, and the surface, as seen in fig. 6a, is distinctly 

 transversely lineate but not broadly transversely wrinkled, as seen in 

 Heer's fig. 1 of pi. xlv. But this difference, as also the length of the 

 leaves, which the author has seen in some fragments reaching 31 to 33 

 millimeters, is not sufficient to eliminate the close affinity indicated by 

 the essential characters ; for the best specimens of Heer have the leaves of 

 the same length as those figured here, and the transverse undulations of the 

 leaves have been remarked by the author upon one specimen only. As in 

 Heer's specimens, the borders of the leaves are flat and smooth and the 

 apex blunt. The species cannot be referred to Taxodium any more than 

 to Sequoia. 



Hab. — Corral Hollow, California.
