Remarks

From Hollick (1930) (p. 52-53)

"This species is represented by numerous specimens in several of the collections from the Yukon region. There is more or less variation in the size and form of the leaves according to the position that they occupy in relation to the twig or branch to which they are attached. They are rather rigid and are closely approximated on the ultimate twigs but are more distant below. The general appearance suggests a relatively open and sparse foliage, a1though this appearance may be more or less due to partial defoliation of the older parts of the twigs and branches. Some of our smaller specimens, represented by Figures 2, 5-9, Plate 15, are suggestive of Torreya venusta Yokoyama (1895) (p. 230, pl. 22, figs. 11, 12, 12a) a Lower Cretaceous species from Japan, which Yokoyama compares with Torreya virginica Fontaine (1889) (p. 234, pl. 109, fig. 8) from the lower part of the Potomac group of Virginia; and they may also be compared with Cephalotaxopsis microphylla Fontaine (1889) (p. 238, pl. 108, fig. 5; pl. 109, fig. 9) but none of our specimens appear to have the rigidity of those depicted in Fontaine's figures."
