Bean’s text below has been edited to emend the parentage (given as C. thyrsiflorus × C. velutinus var. laevigatus).
A natural hybrid between C. velutinus subsp. hookeri and C. thyrsiflorus, reported from Mendocino and neighbouring counties where the two species are in contact. Leaves ovate, to 2{1/2} in. long and 1 in. wide, glabrous, dark green and glossy above, glaucous beneath; three-veined. Flowers pale blue or lavender in almost sessile umbels arranged in racemes or panicles 2 to 4 in. long; common stalk and rachis glabrous. The same hybrid may have occurred in gardens.
