Basionym: Polygalanitida brandegee var. tamaulipana T. Wendt J. Arnold Arbor. 60: 508. 1979
Treatment appears in FNA Volume 10.

Stems erect, hairs closely incurved-appressed, mostly 0.07–0.1 (–0.15) mm, very close to stem, tips touching stem surface. Leaf-blades narrowly elliptic to lanceolate or linear, including basal ones, length 5+ times width, or when leaves in proximal 1/3 of stem broader, then distal leaves lanceolate-elliptic, much narrower than proximal leaves, 5–35 (–40) × 1–3 mm, apex acute to acuminate. Pedicels 1.5–3 mm. Beaks rarely absent. 2n = 36.


Phenology: Flowering early spring–fall.
Habitat: Caliche or shale soils or sands in thorn scrub, oak-savannas, coastal prairies, or montane woodlands.
Elevation: 0–600 m.

Distribution

Tex., Mexico (Nuevo León), Mexico (San Luis Potosí), Mexico (Tamaulipas)
