Discussion:

The plant is sold as Echeveria byrnesii or E. secunda ‘Byrnesii’ – but it certainly is not this species. It is a hybrid and the extremely long and horizontal inflorescences indicate that Cremnophila linguifolia is one parent. Most probably the other parent is E. secunda fa. byrnesii. 


The plant is variable in so far as inflorescences may be long and pendent-decumbent as well as short and fairly upright.
