 Fopulus monodon Lx. 



The leaf has the form of those of P. Gaudini Fisch-Oost. and also 

 the size, but the nervation is more open and the leaf is uot acuminate. 

 It is also coriaceous, a character not indicated by Heer. The species 

 appears to be an American form, perhaps identical, or at least closely 

 allied, to the European P. Gaudini. It has by its nervation a relatiou 

 to Populites Gasparinii, Massal (Flor. Foss., PI. xxvin, fig. 3), and also to 

 the leaf or fragment figured by Heer (Fl. Foss. Arch, vol. I, PI. l, fig. 7) 

 as Phyllites evanescens, especially like it by the nervation more open or 

 nearly at right angles in the upper part. 



Two specimens ; Museum number, 2546. 



Salix Schimperi, n. sp. Plate xiii, fig. 5. 



Leaves membraneous, large, lanceolate, gradually acuminate, nar- 

 rowed, in rounding to the subcordate base, minutely serrulate all around ; 

 nerves thin, open. 



The nervation and areolation of this fine leaf are distinctly of a Salix. 

 The membraneous leaf is thin and in being wetted distinctly shows the 

 characters of the nervation and areolation. It is 15£ em long, 3A CI " broad 

 at a short distance above the base, from which point it is gradually nar- 

 rowed and tapers by a curve to a short petiole, being subcordate at base, 

 as in S. cordato lanceolata of Al. Br., figured by Heer (Fl. Tert. Ilelv., 

 vol. ii, PI. lxviii, fig. 5). The petiole is apparently thick, but is mostly 

 covered. The crenulations of the borders though distinct are very 

 small, turned upward as in S. Lavateri Heer (Fl. Tert. Helv., vol. ii, PI. 

 lxvi, rigs. 1-12). The leaf is not inclined nor curved, but perfectly equi- 

 lateral. 



The leaf is clearly related to 8. cordato-lanceolata Al. Br., but it is 

 twice as large, more distinctly crenulate, thin, membraneous, and the 

 base is less broadly cordate. 



Heer remarks that no fossil Salix leaves of this character have as yet 

 been discovered, and that Braun's species needs confirmation to fix the 

 character of the subcordate base, which may be only the variation of a 

 single leaf. No other leaf of Salix has been found as yet with this one 

 except S. varians, which has the leaves sometimes as large as this, but 

 always narrowed to the base and not rounded and subcordate.
