Fouquieria ochoterenae
This remarkable species is endemic to a small area in southwestern Puebla state where it forms spectacular groves of huge, umbrella shaped spiny trees reminiscent of the Didiereaceae forests of Madagascar.
The trunk of F. ochoterenae is one of the most beautiful in the genus. In the wet season, the trunk is usually green with snazzy gray stripes. In the dry season, the green tends to turn orange, as in this photo. The trunk is often home to species of the bromeliad Tillandsia.
The flowers of F. ochoterenae are very distinctive, each having a short, deep red corolla surmounted by a shaving brush of stamens.
