Parentucellia latifolia (Broadleaf glandweed) is a non-native California herb in the Orobanchaceae family, recognized by European genus established in northern coastal grasslands.
Broadleaf glandweed is a naturalized annual found in northern Central Coast bioregion in grassy areas and roadsides at elevations below 220 meters. Flowering from March to June, this plant produces red-purple flowers with white-tipped lobes, 8 to 18 millimeters long, arranged in spike-like racemes with deeply lobed bracts. Growing with erect, sometimes purple-tinged green stems less than 30 centimeters tall and covered in sticky hairs, the plant has a distinctively hairy appearance. Its generally opposite leaves are sessile, 4 to 12 millimeters long, triangular-lanceolate with dentate margins often tinged purple. The fruit is approximately cylindrical, nearly equal in length to the calyx, containing many minute, smooth seeds.
