Triteleia peduncularis (Long-rayed brodiaea) is a native California herb in the Themidaceae family, recognized by very long pedicels up to 180mm, bright yellow ovary.

Long-rayed brodiaea is a California native perennial found in northwestern and central western California in wet grasslands, vernal streams, conifer and foothill woodlands, often on serpentine soils at elevations below 800 meters. Flowering from May to July, this plant produces white flowers with violet undertones, 15 to 28 millimeters long, arranged on slender scapes up to 80 centimeters tall. Growing with graceful, smooth stems, it develops long, narrow leaves 20 to 40 centimeters in length and 5 to 15 millimeters wide.

The flowers are supported by long pedicels ranging from 20 to 180 millimeters, giving the plant an airy, delicate appearance.
