readily forms extensive clusters, the thin curving leaves of each individual plant merging into a large clump many feet across. The upwards-pointing leaves are green or yellowish green in color, becoming brownish when old or during dry periods; they have long, white, curling hairs along the edges, but usually lack edge teeth. The toumeyana
variety has 40 to 70 leaves per rosette, each between 8 and 18 inches in length, and nearly one inch across, while the less common bella
variety has a greater number (100 to 200) of smaller leaves (4 to 8 inches long, half an inch across).
The plant grows in the mountains of central Arizona, north, east and west of Phoenix.
