JrUASSIC FLOKA OF DOr(;LAS COrXTY. OHEG. } 11 



Podozamite^ Uniaolntu^. None of them are attached, and as they ai-e 

 often not weU preserved, their true position can not he rcjiai-(hHl as 

 positively fixed. There has been, most prolxihly, a union of loo many 

 forms under the general name Podozattiitc^ lanccolalus, as in the ease of 

 Ctadophkins ivhitbicn.^is, and it is possible that some of them are broad- 

 leaved conifers. A few scattered leaflets that agree pretty well with the 

 normal Icnurdldlii^ type oc<'Ui- in tlie Oregon strata. 



PI. XX I \'. I'ig. 17 gives a nearly entire leaf, which has the tip miss- 

 ing, and is by pressure distorted so as to appear convex. Fig. IS gives 

 the greater part of a narrower leaflet. Fig. 19 shows the greater portion 

 of a large leaflet with the base well preserved. This is rounded and 

 broader than the upper part of the leaflet. It may be a leaflet of Znniilcs 

 (jigas (L. <k H.) Carr. It is shown enlarged in Fig. 20. 



The forms occur very rarely at localities Nos. 2, 7, 17, and 18.

Several detached leaflets, nearly entire, were obtained that agree 

 very well with Heer's Podozamites lanceolatus minor. The leaflets are 

 thin in texture, small in size, and narrowed gradually toward the Ijase 

 and apex. The nerves are not distinctly shown, but seem to be numer- 

 ous and closely placed. 



PI. XXV, Fig. 1, shows a nearly entire leaflet, enlarged in Fig. 2. 

 Fig. 3 gives a fragment of a much smaller one, of which Fig. 4 is an 

 enlargement . 



The leaflets are ^'er^- rare. They are most common at locality 

 No. 7, but occur also at locality No. 2. 



a I give in tlie synoiiyiii.v only those references which are designated by the varietal name jninor, although 

 Heer expressly states that the form figured by Ettiiigshausen us the true '/.aniilex distans of Presl (Al)h. k.-k. 

 geol. Reichsan.st., Vol. I, Abth. Ill, No. 3, 18.52, pi. i, fig. 3) from the Rhetic of Bayreuth and Veillalm is 

 the same as those from the Oolite of the upper Amoor. But a comparison of the original figure of Z. dislans 

 in Sternberg's Flora der Vorwelt, Vol. II , 1838, pi. xli, fig. 1 , reveals the greatest similarity to that of Ett ings- 

 hausen. It is also practically identical with Schenk's Z. distans minor (Fl. d. Grenzsch., pi. xxxv, fig. 10), 

 nearer, I think, than his '/.. dUtan.') genuirui (op. cit., pi. xxxvi, figs. 1-3), which he seems to regard as the 

 type. The group is in great need of revision. — L. F. W.
