Vegetative characteristics

Phyllodoce breweri is an evergreen dwarf shrub that reaches stature heights of only 10 to 40 centimeters. The many short, branched branches are lying. The bark of young branches covered with glands.

The densely spread, not overlapping leaves on the branches are needle-like. The leathery, smooth leaf blades are linear with a length of 5 to 20 millimeters and a width of 1 to 2 millimeters with simple or sawn edges.

Generative characteristics

In the western United States, the flowering period extends from June to August. 8 to 30 nodding flowers are arranged in terminal, spike-like inflorescences , and some flowers are formed in the leaf axils. There are two bracts under each flower . The glandular flower stalks are 10 to 15 millimeters long.

The hermaphroditic flowers are radial symmetry and five-fold with a double flower envelope . The five sepals are egg-shaped to lanceolate with a length of 3 to 4.5 millimeters, glabrous on the underside and the edge is ciliate at the top. The five white, light purple to pink petals are bell-shaped with a length of 7 to 9 millimeters with fused to almost the extreme tips; the free, 3 to 4 millimeter long crown teeth are bent back. The nine or ten relatively long stamens tower above the corolla. The stamens are 5 to 8 millimeters long and ciliate at the top. The purple-colored anthers are relatively long with a length of 1.5 to 2.5 millimeters. The spherical with a diameter of 1 to about 2 millimeters ovary is densely covered with glands. The 6 to 8 millimeter long stylus towers over the corolla.

With a diameter of 3 to 3.5 millimeters, the capsule fruit opens with five fruit valves and is hairy with glands.

Occurrence

Phyllodoce breweri occurs in the western United States in California and Nevada . In California, Phyllodoce breweri only thrives in the mountain ranges including the Southern Cascade Range , the San Bernardino Mountains, and the Sierra Nevada ; the distribution area extends into Nevada. It thrives at altitudes of 1200 to 3500 meters in rocky subalpine locations on slopes and meadows.

The new combination to Phyllodoce breweri (A.Gray) A.Heller was 1900 by Amos Arthur Heller published in Muhlenbergia , Volume 1, page 1. A homonym is Phyllodoce breweri Maxim.
