Gratiola ebracteata (Bractless hedge-hyssop) is a native California herb in the Plantaginaceae family, recognized by lack of bractlets and abruptly pointed fruit valve tips.

Bractless hedge-hyssop is a California native annual found in northern and central California Floristic Province, excluding the North Coast Ranges, and in the Modoc Plateau in wet, muddy places at elevations below 2,400 meters. Flowering from April to June, this plant produces white flowers with a yellowish throat, sometimes pink-tinged, on stout erect pedicels. Growing 5 to 20 centimeters tall with simple to branched stems containing 6 to 12 leafy nodes, it forms delicate upright clusters. Its lance-ovate to lance-linear leaves measure 7 to 25 millimeters long, tapering to a point and nearly entire. The spherical fruit is 4-angled with abruptly pointed valve tips, measuring 3.5 to 6 millimeters across.
