About plant names...

Brittlebush, so named because its branches snap easily, is widespread in Mexico and the southwestern United States. Some natives burned the resin of these plants as incense. It is found in dry, gravelly slopes and open sandy washes, at elevations up to 3281' (1 km).

Plants: Forms rounded bushes 12-59" (30-150 cm) high.

Leaves: Leaves are triangular (ovate to deltoid), blue-gray, and 1-3" (3-8 cm) long. Fine matted plant hairs on the leaves give them a silvery appearance.

Flowers: Yellow flower stalks extend outward from the domelike bush. Each flower is 1-1¼" (3-3.5 cm) around. Each is a composite flower, comprised of a central disc with many yellow or purple-brown disc florets, and yellow or orange-yellow ray florets.

Fruits: ¹/₁₆-³/₁₆" (3-6 mm).

Plant Shrubs up to 3' (1 m) in height. They are densely branched, any many of the branches terminate in sharp spines. Forms rounded bushes 12-59" (30-150 cm) high.
Flowers Yellow, or salmon pink, occurring singly or in clusters in leaf axils. Each flower has five petals, and is ⅝-⅞" (1.6-2.4 cm) in diameter. Flower petals are not evenly distributed, so the flower has bilateral symmetry but not radial symmetry. Flowers appear from March to July. Yellow flower stalks extend outward from the domelike bush. Each flower is 1-1¼" (3-3.5 cm) around. Each is a composite flower, comprised of a central disc with many yellow or purple-brown disc florets, and yellow or orange-yellow ray florets.
Leaves Leaves are on long and narrow branchlets, in 2-4 opposite pairs. Each leaflet is ⅛-³/₁₆" (4-6 mm) around, and ovate. Leaf pairs aren’t quite symmetric. Leaves are dropped entirely most of the time. Leaves are triangular (ovate to deltoid), blue-gray, and 1-3" (3-8 cm) long. Fine matted plant hairs on the leaves give them a silvery appearance.
Fruit Pods are ⅞-1½" (2.5-4 cm) long, straight, and con­tain a few seeds. ¹/₁₆-³/₁₆" (3-6 mm).
