Slender-stemmed androsace is a rare (CNPS 2B.3) California native annual found in the southern slope of Willow Creek Mountain in northern Siskiyou County in mountain meadows at an elevation of 1,800 meters. Flowering from May to June, this plant produces delicate white flowers with small corolla tubes that extend beyond the calyx. Growing with thin stems 3 to 12 centimeters tall, it has a glabrous or slightly glandular-hairy structure. Its leaves are small, 3 to 20 millimeters long, ovate to triangular in shape, with fine teeth near the leaf tip and abruptly narrowed to a slender petiole. The plant's multiple peduncles bear small involucre bracts less than 0.5 millimeters wide, creating a delicate, sparse inflorescence.
