upper one* longer, with the uppermost shortened, lower ones shorter and 

 triangular with the upper margin straight , ceins dense, simple, parallel, 

 equal, rising at rigid angles to the rhachis. 



The leaves were petioled (fig. 1, PI. XIII). Segments are in 

 most cases separate from one another but sometimes a slightly conti- 

 guous at base. They may be opposite as in fig. G, PI. VII, or alter- 

 nate as in fig. 1, PI. XIII. They arc always acutely pointed at the 

 angle where the upper and lateral margins meet. They are generally 

 concave in the upper margin and strongly convex in the lower, and 

 are longer than broad ; but in the upper part of the leaf, they are 

 much broader than long (fig. I, PI. VII), with the upper and lower 

 margins more parallel-sided. The lower segments are more or less 

 triangular in shape with the upper margin straight (fig. 6, PL VII, 

 and fig. G, PI. XII). The uppermost segments are comparatively 

 short, as may be seen from fig. 3, PI. VIF, which represents the apical 

 part of a leaf. Fig. 5, PI. VII, is also such an example, while fig. 7 

 and 8a show segments lying intermediate between the apex and the 

 base. 



This species is very closely allied to the European Rhaetic form, 

 N. acuminata Schenk (Flora der Grenzschichten, p. 131, pi. XXXII, fig. 

 1 — 7, XXXIII, 1.), from which, however, it is distinguished by having 

 less acuminate segments, pierced with much denser veins (ca. 3 falling 

 in a millimetre).

 PI. XIII, fig. 3. 



A broken leaf, about 31 mm. in breadth, with the length preserv- 

 ed for GO mm, seems to have been longly-elliptical in shape to 

 judge from its rapidly tapering state both above and below. It also
