of the three primary nerves and of the two lower secondary ones which come 
out of the midrib very obliquely, far above the base of the primary nerves or 
nearly in the middle of the leaf. The borders of the leat are obtusely dentate 
between the lobes, the teeth being short, turned outside, separated by flat 
sinuses. The leaf is 9 em. long, without the petiole, of which only 1 cm. is 
preserved and 5 cm. broad in the middle, cuneiform to the base, decurring 
under the primary nerves, and tapermg upward in narrowing about in the 
same degree. This fine leaf is apparently of the same kind as that in Newberry, 
‘¢ Tllustrations,” Plate XIII. fig. 1, named Populus nervosa, var. elongata. - It 
is however distinctly trilobate, and referable to Platanus, on account of the 
decurring base of the leaves under the lateral primary nerves. 16 specimens. 
48. Populus Raynoldsii, Newby. 23 specimens. 
49. Populus rhomboidea, Lx. 6 specimens. 
50. Populus, species undeterminable. 7 specimens.

51. Ulmus quercifolia, Ung., Iconogr., p. 48, Plate XX. fig. 23. The speci- 
men merely differs from the European species as figured by Unger in the 
narrower more elongated base of the leaves. The borders are sharply dentate, 
the lateral nerves distant, oblique, parallel from the base, passing in a curve 
toward the borders, where they become effaced. 1 specimen. 
52. Ulmus antecedens, sp. nov. Leaves small, thickish, oblong-lanceolate, 
acute, subcordate and subequilateral at base, doubly or triply dentate ; teeth 
short, curved upward ; secondaries thick, parallel, strong and straight, gener- 
ally simple, sometimes forking in the middle, with thick oblique nervilles. 
The leaf has the same character as those of Ulmus crassifolia, of Texas. The 
substance is thick, the size is the same, 4 cm. long, 2 cm. broad in the middle, 
the widest part: the lateral nerves 12 or 13 pairs. 1 specimen.

53. Ficus (Dombeyopsis) grandifolia, Ung. Considered by Schimper a syno- 
nym of Ficus tiliefolia, Al. Br., differs by the coarser texture of the leaves and 
the larger size. Of the leaves which represent this species, one, preserved en- 
tire, is 15 cm. long from the base of the petiole, 18 cm. broad in the middle, 
with the base prolonged downward into two auricles, descending 4 cm. lower 
_than the base of the medial nerve. 8 specimens. 
54. Ficus tiliefolia, Al. Br. 18 specimens. 
55. Ficus Berthoudi, sp. nov. Leaves thick and coarse, broadly cordate at 
base, ovate-lanceolate, acuminate above, entire, enlarging toward the base and 
rounding to the petiole, descending lower than its top, sometimes auriculate, 
the basilar border in one leaf overlapping the top of the petiole; primary 
nerves deep and broad; lower lateral nerves opposite, the upper alternate, all 
very deeply curving toward the borders and following them in a series of
