JURASSIC FLORA OF DOUGLAS COUNTY, OREG. 131 



appear to have been made by the bases of the leaves and are smaUer 

 than they would be if made by the surface of the boss-like leaves. The 

 shape, too, would differ if made under these conditions. 

 This plant occurs at localities Nos. 2, 7, and 17. 



Family PINACE^. 



Genus ARAUCARITES Presl. 



Araucarites ? sp. Fontaine (cone scale). 



PI. XXXV, Fig. 9. 



At locality No. 7 an apparent cone scale of Araucarites was found 



in a single specimen. It is quite convex, appearing hard and rigid, 



and was apparently quite thick. It is cuneate in form, expanchng into 



a broad thick summit, the extreme tip being hidden. Toward the 



opposite end it narrows considerably, and at the end shows traces of 



former union with the axis of the cone. Its width at the summit is 18 



mm. and its length 25 mm.

At several of the Oregon localities there are a number of long Pinus- 

 like leaves that are always detached. They never appear in such numbers 

 as the leaves of Taxites zamioides, but are more scattered. They agree 

 well with the larger forms attributed by Heer to Pinus Nordenskioldi. 

 Some of them, however, are a good deal larger than any given by Heer. 

 These larger forms can not be separated from certain smaller ones found 

 in the Oregon flora, which agree very well in size with the largest of Heer. 

 These leaves are pretty surely those of a Pinus and not of a Taxites. 

 They narrow gradually to subacute tips and do not narrow to the base. 

 In one case a fragment of the sheath may be seen attached to the base of a 

 leaf, and two other leaves lie near this, as if they had once all belonged to 

 the same bundle. There is a considerable variation in the size of the leaves. 

 The largest leaves, none of which were seen entire, have a length of 115 mm. 



« I do not include the Cychpitys Nordenskioldi (Heer) Schmalh. in the synonymy of this species, because 

 after carefully comparing Schmalhausen's figures with those of Heer, I have grave doubt whether Schmalhausen 

 had this plant at all. His genus Cyclopitys seems to be quite distinct. — L. F. W.
