PLANTS FROM CURRY COUNTY, OREG. 151 



larger leaf is torn in half longitudinally, and the smaller one shows the 

 basal part nearly complete. The larger leaf gives the shape best, and 

 hence this will be taken for description. It is 35 mm. long, oblong in 

 form, and tends to assume a flabellate shape. It narrows slightly toward 

 the base and was attached by the middle point of the base, which was 

 slightly auriculate. It is widest near the end, which is rounded off very 

 obtusely. It was probalDly 25 mm. wide near the end. The nerves are 

 very fine and closely placed. They diverge from the insertion of the base 

 and fork repeatedly, so as to fill the lamina of the leaf. In form and size 

 the leaves resemble those of Otozamites Klipsteini superha Sew., from the 

 Wealden of England. They most reseml^le those of the form figured on 

 pi. vii, fig. 9, of Seward's Wealden Flora, Pt. II, but the leaves now in 

 question narrow more toward the base. 



Taxites zamioides (Leckenbj-) Seward." 

 PI. XXXVIII, Figs. 15-18. 



The principal specimen regarded as representing Taxites zamioides is 

 a small bit of a twig with the bases of several leaves attached to it. 

 Enough of the leaf is preserved to show a ver}^ close agreement with the 

 T. zamioides of the Lower Oolite of Yorkshire, England. On some of the 

 specimens several detached leaves occur that are nearly entire, and which 

 agree well with those of this conifer. This conifer occurs at some of the 

 Jurassic localities in the vicinitj' of Buck Mountain, Oregon, not rarely, 

 and has been described by the writer in this paper. This is shown natural 

 size in PL XXXVIII, Fig. 15, and enlarged in Fig. 16. A single nearly 

 complete leaf found detached is represented in Fig. 17, and Fig. 18 shows 

 this enlarged. 



The above-described plants are all that can be made out with any 



degree of certainty in the collection from Curry County. They indicate 



with a high degree of probability that the strata which yield them are of 



the same age as the Jurassic strata of Douglas County in the vicinity of 



Buck Mountain. The abundant plant fossils of these beds show that they 



are of Lower Oolite age.
