FicMs dalmatica, Ett. 

 Plate LXIU, Figs. 3-5. 



Ficus dalmatica, Ett., Eoc. Fl. d. M. Prom., p. 13, pi. vii, fig. 11. — Lesqx., Annual Report, 1874, p. 303. 



Leaves subcorticeous, entire, narrowly ovate-lanceolate, obtusely acuminate, narrowed in a curve 

 to a short, thick petiole ; midrib thick, especially toward the base ; basilar lateral nerves at a more acute 

 angle of divergence than the upper ones, ascending to the middle of the leaves; secondary nerves camp- 

 todrome, joined by transverse oblique nervilles. 



As seen in fig. 3, the leaves are attaclied to the stem by a short petiole, 

 which in fig. 4 appears inflated by the decurrent border of the leaves. The 

 lower lateral nerves, joining the midrib a little above the border base under 

 an angle of divergence of about 30°, are iuequidistant from the upper ones, 

 which are more open, parallel, and curving along the borders, anastomosing 

 in simple bows and united by distinct veinlets more or less oblique to the 

 veins. The base of fig. 5 is not seen, and is represented truncate, an appear- 

 ance caused by its reversement into the stone, the upper part of the leaf 

 being flattened upon the specimen and the lower curved back or forced down 

 into the imbedding matter. All the leaves are small, varying from three and 

 a half to five and a half centimeters long without the short petiole, and one 

 and a half to nearly two centimeters broad below the middle. Though the 

 species from Promina is represented by a single leaf, its general form, the 

 characters of the nervation, the basilar decurrent jiart enlarging the petiole, 

 a part evidently destroyed in the European specimen, are so distinctly alike 

 that I do not find any reason for doubting identity; even the slightly obtuse 

 points of the leaves inclining to one side are exactly similar in lx)th fig. 11 

 of Promina and fig. 4 of our plate. 



Habitat. — Point of Rocks, Wyoming (Dr. F. V. Hayden, Win. Cleburn). 



Ficus spcctabilis, Lesqx. 

 Plate XXXIII, Figs. 4, 5, G. 

 Ficxii spectabilis, Lesqx., Annual Report, 1872, p. 379. — Schp., Pal. V6g6t., iii, p. 595. 



Leaves variable in size, mostly large, coriaceous, entire, broadly ovate, lanceolate, acuminate, 

 rounded to the petiole ; nervation distinct, camptodrome. 



The first description of this fine species was made from fig. 5, one of 

 the largest leaves, by which it is represented until now. It is fifteen centi- 

 meters long, eight centimeters broad below the middle, whereit is the widest, 

 with the point broken, as it is also in all the other specimens obtained later. 

 The lowest ])air of basilar nerves are opposite, sometimes slightly stronger, 

 as in fig. 5, but sometimes also passing to mere marginal simple veins, becom-
