Description

Calochortus tolmiei is a perennial herb producing a slender stem, branched or unbranched, to 40 centimeters in maximum height. There is a basal leaf up to 40 centimeters long which does not wither at flowering, and generally a smaller leaf farther up the stem.[2]

The inflorescence is a solitary bloom or a cluster of bell-shaped flowers. Each has white to pale pink or purple petals, each up to 2.5 centimeters long, and three narrower sepals beneath. The petals are usually very hairy on their inner surfaces, and may be fringed with long hairs as well.[2]

The fruit is a winged capsule 2 or 3 centimeters long containing several dark brown seeds.[2]
