Discussion
Colubrina stricta is known in the flora area only from historic collections (during 1850) at the type locality in Comal County and a few more recent collections from one site in Hueco Tanks State Park in El Paso County. It is more continuously distributed and abundant in Mexico (G. L. Nesom 2013). Validation of the epithet by M. C. Johnston (1969) was superfluous.
