 PI. XII, Fig. 1. 



Heer, Fl. Foss. Arct., vol. 6, 2 Abth., p. 66, PI. xli, Fig. 2 ; PI. XLVi, Fig. 12e. 



Leaves oblong-, quite entire, emarginate at apex, gradually narrowed 

 to the base ; secondaries thin, camptodrome, the lower pairs only opposite. 



This leaf has the same characters as that represented by Heer (loc- 

 cit., Fig. 2), being only slightly larger and better preserved, the base only 

 being destroyed. It is 6"" long, a little more than 2"" broad in the upper 

 part, and with seven pairs of secondaries, curved in passing towards the 

 borders at an angle of divergence of 40°. The texture is subcoriaceous. 

 Its close relation to 31. Schimpcn has been remarked above.

Mtbica longa Heer. 

 PI. Ill, Figs. 1-6. 



Proteoides longus Heer, Fl. Foss. Arct., vol. 3, pt. 2, p. 110, PI. xxxr, Figs. 4, 5 ; PI. 

 XXIX, Fig. 8b ; ibid., vol. 6, 2 Abth., p. 65, PI. XViii, Fig. 9b ; PI. xxix. Figs. 15-17 ; 

 PI. XXXIII, Fig. 10 ; PI. XLI, Figs. 4b, d. 



Leaves coriaceous, linear, attenuated to the base, obtuse at the apex, 

 entire ; secondaries very thin. 



The characters are in accordance with the description and tigures of 

 Heer as above. The secondaries are obliquely curved in passing through 

 the blade and are extremely thin and difficult to perceive. Fig. 3 agrees 

 with that in Fl. Foss. Ai'ci, vol. 3, pt. 2, PI. xxxi, Fig. 4, which has the 

 leaves linear, of the same width and somewhat curved, while Fig. 1, and 

 more especially Fig. 2, has the same characters as that in Fl. Foss. Arct., 

 vol. 6, 2 Abth., PI. XXIX, Fig. If), the leaves being a little more enlarged in 

 the middle and narrowed upward and downward in the same degree. Fig. 

 G has the same form and size as Heer's Fig. 8b, PI. xxix (loc. cit).
