A. sanguinea. These, together with a low scrubby oak tree, with small perennial leaves, were the only trees collected about Cosihuiriachi. A species of Juniperus, with red berries, a Thuja, and a small-leaved Cowania(?)[1] all of them in fruit, were also brought from there.
Between Chihuahua and Cosihuiriachi, but especially about the latter place, the porphyritic soil produced a number of Cactaceae, some strange Echinocacti, several Mammillariae, a few Opuntiae, and principally a great variety of Echinocerei. One of the latter is completely covered with stout and long spines;[2] another has short radiating spines, closely adpressed to the plant;[3] a third has short radiating spines, with single, stout black central ones, which project from the plant in all directions;[4] a fourth is distinguished by its longer and curved reddish radiating spines, with a stouter one projecting from their centre.[5] I have all of these in
