Kalmiopsis leachiana, commonly referred to as Siskiyou kalmiopsis,[1] is a rare flowering plant endemic to the Siskiyou Mountains of southwest Oregon, where it is specially protected in the 179,755-acre (727.4 km2) Kalmiopsis Wilderness reserve.

It was discovered in 1930 by Lilla Leach in the Gold Basin area.

Kalmiopsis leachiana is an evergreen shrub growing to 10–30 centimetres (0.33–0.98 ft) tall, with erect stems bearing spirally arranged simple leaves 2–3 cm long and 1 cm broad.

[citation needed] The flowers are pink-purple, in racemes of 6–9 together, reminiscent of small Rhododendron flowers but flatter, with a star-like calyx and five conjoined petals; each flower is 1.5–2 cm diameter.

The fruit is a five-lobed capsule, which splits to release the numerous small seeds.
