THE FLORA.

The status of F. irregidans at Point of Rocks, 

 Wyo., is hardly more satisfactory. The single 

 specimen figured by Lesquereux *^ as from this 

 locality is No. 295a of the United States Na- 

 tional Museum collection and represents only 

 the petiole and extreme basal portion of a leaf. 

 I admitted this species in my "Flora of the 

 Montana formation " on the basis of this ex- 

 ample alone, for none other seems to have been 

 found, but I doubt the wisdom of so doing with- 

 out further reservation. So far as can be made 

 out from so small a portion it might have be- 

 longed to F. irregularis, and on the other hand 

 it would be equally hard to exclude it from a 

 number of other species of similar size. In any 

 event, if admitted as a member of the Montana 

 flora, its status as above outlined should be 

 distinctly recalled and weighed accordingly. 



As noted in the sAmonymy, one of the two 

 leaves figured by Ward is with little doubt 

 RTiamnus goldianus. It has a slightly but dis- 

 tinctl}" heart-shaped base vnth a number of 

 short tertiaries going out from the lower side 

 of the lowest pair of secondaries, exactly as 

 Lesquereux described for B. goldiamis and 

 quite unlike typical Ficus irregularis. The 

 latter has a wedge-shaped base, with no ter- 

 tiaries on the loM^er side of the lowest pair of 

 secondaries. 



In the material collected by Ward in 1883 

 and figured but not described is one specimen 

 obtained in white sandstone at a point 1| 

 miles southeast of Golden and therefore prob- 

 ably in the true Laramie ; and a leaf which can 

 hardly be distinguished has been found at 

 Marshall, Colo. 



Occurrence : Laramie formation, Marshall and 

 IJ miles south of Golden, Colo. Denver for- 

 mation, Golden, Colo, (types). "Upper Lara- 

 mie," Carbon, Wyo. (doubtful). Mesaverde 

 formation, Point of Rocks, Wyo. (doubtful).

This European species was identified by 

 Lesquereux with specimens from Point of 

 Rocks, Wyo. One of these specimens (No. 

 294, U. S. Nat. Mus., original of Lesquereux's 

 PI. LXIII, fig. 4) is in the United States 

 National Museum and agrees very closely with 

 the figures of this species in Ettingshausen 's 

 paper above cited, though it is perhaps to be 

 doubted if they are really identical. 



In the collections from Coal Creek there is a 

 single leaf — the one here figured — that is 

 almost the exact counterpart of figure 4 of 

 Lesquereux's Plate LXIII. Another leaf 

 shown in Plate XXII, figure 5, also from Coal 

 CVeek, is referred here with some question. It 

 is not well preserved, and its characters are 

 made out with difficulty. 



Occurrence: Laramie formation. Coal Creek,

Ficus neodalmatica Knowlton, n. sp. 



Plate VII, figure 6. 



Ficus neodalmatica Knowlton [nomen nudum], U. S. 

 Geol. Survey Bull. 69fi, p. 283, 1919. 



Leaf of small size and firm texture, ovate- 

 cuneate, broadest at or near the middle, from 

 which it narrows regularly to the base and 

 above to the obtusely acuminate apex; midrib 

 very thick, especially below; lower pair of 

 secondaries arising at the base of the blade, 

 at a much more acute angle than the ones 

 above, passing up to or above the middle of 

 the leaf and there joining by a broad loop with 

 the pair next above; upper secondaries about 

 four pairs, alternate, at irregular distances, 

 camptodrome, each joining the one above by 

 a broad loop well inside the margin and with 

 a series of loops outside; nervilles sparse, 

 mainly broken. 



The leaf figured is nearly perfect. It is 

 slightly unequal sided, being ovate-cuneate, 

 with a wedge-shaped base and an obtusely 

 acummate apex. It is 6.5 centimeters in 

 length and 3,5 centimeters in width at a point 

 a little above the middle of the blade. This 

 species is undoubtedly most closeh' related to 

 what Lesquereux has figured from Point of 

 Rocks, Wyo., as Ficus dalmatica Ettuigs- 

 hausen.'^ It diflfers from that form in its
