The plant grows caespitosely, with 5 to 6 dense rosettes growing from a thick caudex. The leaves are not very numerous, broadly ovate, 4 to 7 cm long, broadest at the base, thick, and pale green but not glaucous. The peduncle is 25 to 30 cm high, with bracts 1 to 1.5 cm long, ovate, acute, and sagittate at the base. The inflorescence is slightly glaucous. The pedicels are short, 3 to 6 mm long. On the flower, the calyx is 5 mm long, deeply 5-cleft, with the lobes triangular-ovate. The corolla is a reddish yellow. [3]

Distribution and habitat

This species is endemic to the Baja California Peninsula and the surrounding islands. It occurs in extreme southern Baja California and northern Baja California Sur. It is also present on Cedros Island. [2]
