This member of the Scrophulariaceae family was given this name by Francis Whittier Pennell in 1947. It is found around 1000 meter height in Mexico, growing in a well drained soil with quite some water in summer and next to nothing in winter. Plenty of sun, and it will get lots of pink (rare form: white) flowers. The caudex can grow to ten centimetres or more, the vines will reach for two to three meters.
The genera name from the Spanish name for the plants. The species name for the red flowers. And this is my own.
