Specimens found in Nevada and China, and fossils of related species, like Ornithoprion, began to bolster the idea that the tooth whorl was part of the lower jaw.
By the end of this month, most of the species had ripened their seeds, but undecayed, still seemed to be in bloom from the numerous corolla-like involucres and whorls of chaffy scales of the composite.
The other species, Abies concolor, attains nearly as great a height and thickness as the magnifica, but the branches do not form such regular whorls, nor are they so exactly pinnated or richly leaf-clad.
