"Plate 22, Figures 1, 2"

"Branches and twigs with relatively sparse, rigid, narrow acicular leaves on the ultimate twigs, and shorter, thicker leaves at the bases of the twigs and on the supporting branches."



From Hollick (1930) (p. 58)

"These specimens represent a form in which the leaves are intermediate in character between Sequoia rigida Heer (1874) (pp. 80, 91, 102, 128, pl. 22, figs. 5g, 11a; pl. 25, fig. 6; pl. 27, figs. 8a, 9a, 9b, 10-12, 12a, 13, 14; pl. 38, figs. 9a, 10, 11,) and Sequoia spinosa Newberry (1882 [1883]; 1898) (p. 21, pl. 53, figs. 4 (5?)). The former is a species well represented in the Kome and Atane beds of Greenland, and the latter is based upon a single fragmentary specimen, presumably of Tertiary age, from Cook Inlet, Alaska. Our specimens closely resemble Newberry's figure of the leafy twigs, but inasmuch as the species is known to me only by Newberry's description and figure, and as it has not been recorded from elsewhere than the type locality, its specific status and identity appear to be more or less uncertain. Except that the leaves in our specimens are more sparse or more widely spaced than in Sequoia rigida, they might be regarded as specifically identical, as may be appreciated by comparison with Heer's Figures 9a and l0 on Plate 27, and varietal relationship, at least, may be properly indicated in the name adopted. The possible status of our specimens in relation to Newberry's species must, for the present, remain a matter of individual opinion."
