Monographs Details: Ficus canadensis
Authority: Hollick, Charles A. 1927. The Flora of the Saint Eugene Silts, Kootenay Valley, British Columbia. Mem. New York Bot. Gard. 7: 389-428.
Description:Species Description - Leaves apparently oblong-ovate in shape, petiolate, entiremargined, with rounded or obscurely cordate bases and simple pinnate nervation. The secondary nerves are alternately arranged, subparallel, subtending uniform angles of about 45° with the midrib, ascending and curving upward in the marginal region. The petioles are stout and from 2 to 3 centimeters in length.

The original specimen upon which the generic identification was based is represented by the specimen figured on PLATE 36. The more complete specimen, represented by FIGURE 1 on PLATE 37, gives a better idea of the salient characters of the outline and main nervation; but the finer nervation, unfortunately, is not discernible. The specimens are comparable with leaves of several existing species of figs, especially with those of the general type represented by Ficus Krugiana Warburg, a species native in the West Indies (see PLATE 45); and among the hundreds of different fossil leaves that have been referred to the genus Ficus are a number that represent the same general type as ours; in fact, the number of comparisons that might be made, with existing and extinct species, is so numerous as to render them of no value in attempting to arrive at any satisfactory conclusions in regard to specific relationship or geologic age.
Whether or not these leaves and the fruit previously described under the name Ficus interglacialis may belong to one and the same species, must, of course, remain an open question until such time as the two may be found actually attached to the same branch; hence in the meantime I have given to each a distinctive specific appelation.
