"Width, are generally five centimeters long, even more. In both forms^ 

 they are marked by a broad indistinct middle nerve, and the surface, 

 seen with the glass, appears very thinly striated in the length. This char- 

 acter, as well as the thick consistence of the leaves, seems to prove the 

 identity of the species, though the leaves of the specimens of Point of 

 Kocks are not only longer but proportionally narrower and scarcely con- 

 tracted to the point of attachment to the branches. In both, these leaves 

 are generally crowded and covering' the stem.

6. Sequoia biformis, s}). nov. 



Stems thick, piunately branching; branchlets short, obliquely di- 

 verging; leaves either linear or somewhat broader in the middle, grad- 

 ually narrowed to a point, slightly contracted to the decurrent base, 

 slightly, incurved or falcate, sometimes erect and appressed to the stem ; 

 scar-leaves triangular or lingulate-pointed. 



This species apparently bears two kinds of leaves, even upon the same 

 specimens; either long, two centimeters,and very narrow-linear, less than 

 one millimeter wide, or shorter and broader,- decreasing gradually from 

 the base to the point, linear-lanceolate, nearly one and one-half millime- 

 ters wide and only eight to ten millimeters long ; tlie middle nerve is 

 deeply marked upon both kinds of leaves. 1 should have considered the 

 numerous specimen s bearing branches of this Sequoia as representing two 

 species, the one with narrow longer leaves, the other with shorter broader 

 leaves. But even the difference in the length and proportionate width of 

 the leaves is distinctly perceivable upon one of the specimens, and the 

 difference also in the length of the leaves, all narrow and of the same 

 width, is evident upon another. There are, moreover, a large number 

 of vspecimeus, all fragmentary indeed; and the difference in regard to the 

 size of the leaves is apparent upon most of them. In the average, the 

 leaves are much narroAver than those of Sequoia Reichenhachi, Heer, to 

 which this species is related by the falcate form of some of the leaves.

7. Widdring-tonia complanata, S2h nov. 



Stem thick, disticho-pinnate; branchlets short, thick, alternate, 

 oblique ; leaves small, in spiral order, closely imbricate and appressed, 

 oblong-lingulate pointed upon the primary branches, ovate-pointed or 

 rhomboidal and shorter upon the obtuse branchlets. 



This species, represented by many specimens, is evidently related to 

 Widdringtonia antiqua (Sap. Et., 2,'l, p. 69, PI. I, fig. 4), for the form of 

 the leaves, which are, however, more closely appressed in the American 

 species, and more distinctly placed in spiral order around the branch- 

 lets. These leaves do not appear of a thick substapce, the coat of 

 coaly matter over them being extremely thin. 



8. FlCUS ASAEIFOLIA, Ett. 



Leaves petioled, broadly reniform, subcordate or subpeltate, very 

 obtuse, small, with borders crenulate ; primary nerves palmately five 

 to seven; middle nerve straight; upper lateral ones strong, curving 

 inward, branching and anastomosing with the upper secondary veins ; 

 veinlets transversal, their ramification forming a protuberant, or em- 

 bossed, very distinct, polygonal areolation. 



Though this species has been already briefly described from speci- 

 mens found at Golden, in Dr. F. Y. Hayden's Report for 1872 (p. 378), it 

 had as yet not been figured, the fragments of leaves being generally
