Carex texensis (Torr. ex L. H. Bailey) L. H. Bailey

Carex texensis is introduced into California, New Jersey, New York and Ohio. Due to confusion with C. retroflexa, C. texensis is probably under-recorded.

Plants without conspicuous rhizomes. Culms 10–30 cm, 0.5–1 mm wide basally, 0.4–0.5 mm wide distally. Leaves: sheaths tight, green, fronts hyaline; ligules less than 2 mm, wider than long; widest leaf blades 1–1.7 mm wide. Inflorescences with 3–8 spikes, 0.6–3 cm × 5–6 mm; proximal internodes 1–2 times as long as proximal spikes; proximal bracts to 1(–3) cm; spikes with 3–10 spreading or reflexed perigynia. Pistillate scales hyaline or pale brown with green midvein, ovate, 1.8–2.4 × 0.8–1.3 mm, body 2/3 to almost length of perigynia, apex acute, acuminate or short-awned. Anthers 1 mm. Perigynia green to pale yellow, faces not veined, 2.6–3.4 × 1–1.3 mm, base of body spongy, thickened, longitudinally striate adaxially, spongy region 0.7–1.1 mm, margins entire, usually serrulate distally; beak 0.7–1.1 mm, apical teeth 0.1–0.3 mm. Stigmas straight or slightly twisted, 0.05 mm wide. Achenes ovate, 1.3–1.5 × 1–1.1 mm.
