Stems erect, occasionally without clear central stem, unbranched or branched throughout, branches usually few, ascending, strigose and spreading-hirsute. Leaves usually few, oblanceolate, linear, or narrowly oblong, 10 to 50 × 2 to 5 mm, tips acute to rounded, surfaces appressed- to ascending-hirsute, pustulose, pustules larger on margins and abaxial surfaces. Inflorescences cymules solitary, rarely paired, 1 to 5 (10) cm in fruit, proximal-most flowers usually not touching; bracts occasionally 1 to 2 at cymule base, resembling vegetative leaves; pedicels 0 to 0.5 mm in fruit. Flowers ascending to spreading, promptly deciduous at maturity; calyces symmetric, cylindric to ovoid, bases widely rounded, slightly constricted distally, 1.5 to 2.5 mm at anthesis, 4 to 6 mm in fruit, lobes separate to base, linear to lanceolate, margins often densely whitish ascending-hirsute, midribs slightly thickened and ascending to inclined coarse-hispid, hairs pustule-based, tips erect to slightly recurved, abaxial surfaces finely appressed-hirsute, adaxial surfaces glabrous proximally, appressed short-hirsute near tips; corollas funnel­form, tubes 1 to 1.5 mm, limbs 1 to 2 mm in diameter; fornices min­ute; gynobases extending to 75% and styles to slightly < length of mature nutlets; flower bracts absent. Fruits (3)4, homomorphic, lance-ovate, usually compressed, 1.8 to 2.2 mm, grayish to brownish, occasionally mottled, bases truncate, margins rounded, tips narrowly acute rounded, slightly acuminate, surfaces dull, uniformly minutely tuberculate-spinulose, spinule projections short, cylindric, transparent, and apically rounded to sharp-tipped, abaxial surfaces low convex, usually flat, spinal ridges absent to obscurely present, adaxial attachment scars centered, edges not raised, abutted entire length or variably narrowly gapped, widely bifid-forked at base, occasionally gapped to form minute areole.
