JUEASSIC FLORA OF DOUGLAS COUNTY, OREO. 85 



minal portion of what was probably a central leaf. This is less inequilat- 

 eral than usual and is subacute at the tip. Fig. 7 shows a smaller sized 

 inequilateral leaf, with a prolonged wedge-shaped base. Fig. 8 shows 

 the basal portion of a large inequilateral leaf, with the wedge-shaped base 

 less prolonged, and showing a trace of the stipe. Fig. 9 gives an abnor- 

 mally small leaf. Fig. 10 shows an abnormal broad elliptic leaf, with little 

 development of the midnerve. Fig. 1 1 shows the nerves better than most 

 specimens. 



The plant occurs abundantly at locality No. 19 and is not rare at No. 2. 

 It also occurs at localities Nos. 1, 7, and 16.

"This is the plant that Mr. Seward (Jur. Fl. Yorksh. Coast, p. 162) calls "Sagenopteris PMllipsi (Brong- 

 niart)." He heads the synonymy with the reference to Brongniart's Hist. Veg. Foss., p. 225, where he describes 

 Glossopteris PhilKpsii, but dates it 1828. This, it is true, is the date of the first volume, but it is well known 

 that the work was published in parts, and it is very difficult now to ascertain the dates of the fascicles on 

 account of the vicious habit of destroying the covers in binding such volumes. M. Rene Zeiller has been 

 to great pains to determine the dates of the parts of this work and has been sufficiently successful for all prac- 

 tical purposes. His results may be found in the text to his monumental work on the flora of the coal basin 

 of Valenciennes. (Ministere des Travaux Publics. Etudes des Gites Minc^raux de la France. Bassin Houiller 

 de Valenciennes. Description de la Flore Fossile, par R. Zeiller. Texte. Paris, 1888. Index bibliograph- 

 ique, pp. 701fE, cf. p. 703). From this it appears that page 225 was in the 5th livraison, issued in 1830 

 together with pi. Ixi bis, containing the first figure. PL Ixiii, containing the other figure, was included in the 

 6th livraison, which appeared in 1831 or 1832. Now as Brongniart puts Pecopteris paurifolia Phill. in his 

 synonymy, it might have been seen that Phillips's work had then appeared, and that the date must have been 

 later than 1829. This also shows that Brongniart regarded Phillips's plant as the same as his, coming as 

 they all did from the same locality. He, of course, had no right to change the specific name, but the rules of 

 nomenclature were very loose in those days and still are with some authors. There seems to be no escape 

 from recognizing Phillips's name. — L. F. W. 



''Although Goppert expressly excludes Brongniart's forms from his synonymy, and deals only with those 

 of Lindley and Hutton, he retains Brongniart's specific name, which is incomplete without his authority 

 attached. Goppert's reasons for separating the forms are no longer considered valid. Mr. Seward includes 

 the Aspidites Nilsonianus, to which Goppert refers Brongniart's forms, in his synonymy, but they form only 

 a part of it, and that name relates to Brongniart's Filicites Nilsonianus, which Presl later renamed Sagenop- 

 teris rhoijolia (cf. Twentieth Ann. Rep. U. S. Geol. Surv., Pt. II, 1900, p. 3.52). I therefore omit it from the 

 synonymy of this species. — L. F. W.
