^'This is the plant tliat Mr. Seward (Jur. Fl. Yorksh. Coast, p. 162) calls "Sagenopieris PhilHpsi (Brong- 

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

 Gidssopleris PhiUipsii, but dates it 1828. Tliis, it is tnip, is the date of tlie first volume, but it is well known 

 that the work wsis published in parts, and it is very difricult now to ascertain the dates of the fa.scicles on 

 account of the vicious h'?il)it of destroying the covers in binding sucli volumes. M. Kenr Zeiller has been 

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

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

 of Valenciennes. (Ministere des Travaux Publics. Etudes des Oites Mineraux do la France. Bassin Houiller 

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

 ii|ue, pp. TOUT, cf. p. 703). From this it appears that page 22.5 was in the 5th livraison, issued in 18.30 

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

 Oth livraison, wliich appeared in 1831 or 1832. Now as Brongniart puts Pecojilrris jmucijolta I'hill. in his 

 synon3-my, it might have been seen tliat Phillips's work had then appeared, and that the date must have lieen 

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

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

 nomenclature were very loo.se in those days and .still are with .some authors. There seems to bi' no escape 

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



''Although (ioppert expressly excludes Brongniart's forms from his synonymy, and deals only with (hose 

 of Lindley and Iluttcm, 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 jUpiditts Xilsonianus, to which Gi'ippcrt r(>fers Brongniart's forms, in his .synonymy, but (hey form only 

 a part of it, and that name relates to Brongniai'l's Fdicites NiJ>!(mianus, which Prcsl later renamed Sii<]enf>/>- 

 teris rhoilotia (cf. Twentieth Ann. Kep. U. S. Geol. Surv., Pt. II, lOOO, p. 3.52). 1 therefore omit it from (he 

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