Discussion
Zeltnera glandulifera is endemic to Brewster, Pecos, and Terrell counties in trans-Pecos Texas. Its range is about 200 km west of that of Z. beyrichii.
Zeltnera glandulifera is similar to Z. maryanniana, from which its range is wholly southeast. The species differs most distinctly in that its stems, leaf and calyx midveins, and especially its pedicels and inflorescence branches are copiously papillose-puberulent, mostly in lines.
