Plentiful about Kerrville, especially along the Guadalupe and Town 

 Creek, usually in gravelly or stony ground. Not only the throat of the 

 calyx and the disk-shaped stigma are dark black-purple, but also the 

 throat of the corolla. Of the hundreds of flowers seen, hardly a half 

 dozen were without this marking. The variety pinifolia is merely a 

 very narrow leaved form of this species. Both forms grow together and 

 there is no other character to distinguish them.
