Keckiella corymbosa (formerly Penstemon corymbosus) is a species of flowering shrub in the plantain family known by the common names redwood keckiella, red beardtongue,[1] and red shrubby penstemon.[2]
It is endemic to California, where it grows in the forests and chaparral of the central and northern regions of the state.[3]
Keckiella corymbosa is a narrow, erect keckiella, reaching up to about half a meter tall and less than a meter in width. Its spreading branches have oppositely-arranged pairs of narrowly oval-shaped leaves one to three centimeters long and with smooth or vaguely toothed edges.[3]
The plant produces inflorescences on hairy pedicels with many flowers. Each flower is tubular opening into a wide mouth with three narrow, pointed lower lobes and two upper lobes joined into a straight flap or curving lip. The flower is up to 4 centimeters wide and 3 long, and is bright red to orange red or deep pink. Inside the mouth are long filamentous stamens and one flat, yellow-hairy sterile stamen called a staminode.[3]
