knowlton.] DESCRIPTION OF SPECIES. 49 
larger secondaries above, and the ((Mitral nerve or midrib apparently 
unbranched. Nervilles mostly forking and only preserved within the 
outside pair of nerves. 
This species is suggestive of Ficus planicostata Lx., 1 but differs 
from it markedly in having five instead of three palmately arranged 
nerves. It approaches in shape to Ficus planicostata var. latifolia Lx., 2 
[now F. latifolia (Lx.) Kn.] the main difference being the number of 
nerves. The two lower secondaries on the outside are much stronger, 
but they are true secondaries and arise from the lateral nerves some 
distance above the base. The finer nervation is the same in both. 
This species resembles a number of other fossil leaves, as, for exam- 
ple, Smilax grandifolia-cretacea Lx., 3 from the Dakota group of Kansas; 
but the resemblance is only superficial. It is perhaps much closer to 
Dombeyopsis Herbert i Wat., 4 which has the same shape and base, as 
well as the five nerves, but differs in not having the outer pair with 
numerous secondaries, and also in the finer nervation. 
It is possible that this may be only a small leaf of Ficus speciosis- 
sima Ward, 5 which comes from the same beds. This latter species is 
about five times the size of F. Wardii, and is probably only a slight 
form of F. planicostata latifolia. It differs, however, from F. Wardii 
in being really three-nerved, although appearing five-nerved. The 
lowest pair of secondaries on the outside are copiously branched, but 
not so in F. Wardii.

This species was first identified by Lesqnereux from specimens 
obtained at Golden, Colorado, presumably from the tuffaceous deposits 
of Table Mountain, but as these specimens can not be found in the 
United States National Museum collections, it is impossible to be certain 
of this. Not one of the recent collections contains even a fragment 
of it, but a single example is reported by Lesquereux 6 in the large col- 
lection made by liev. Arthur Lakes for the Cambridge Museum.
