Schreiber's manzanita is a rare (CNPS 1B.2) California native shrub found in the southwestern San Francisco Bay Area, specifically on the northern Ben Lomond Mountain and northwestern Santa Cruz County, inhabiting siliceous shale outcrops, chaparral, and knobcone-pine woodland at elevations of 180 to 650 meters. Flowering from January to March, this plant produces white to pink flowers in pendulous panicles with delicate glandular-hairy branches. Growing one to two meters tall with erect stems, it displays soft-hairy twigs and distinctive gray-canescent foliage. Its leaves are oblong to oblong-ovate, two to five centimeters long, with a glaucous dull surface and slightly lobed base that clasps the stem. The fruit is a sticky, depressed-spheric structure seven to fourteen millimeters wide, covered in glandular and nonglandular hairs.
