Bouchetia erecta

Herbs antrorsely strigillose, hairs of 2 types: glandular-capitate, spreading, translucent to white, frequently with darker tip, 0.1 mm, and eglandular, white, 0.1–0.5 mm. Stems to 25 cm. Leaves various, decreasing in size from stem base to apex, sparsely to moderately pubescent, basal leaf blades spatulate to oblanceolate, 1.6–4 × 0.4–1.4 cm, base narrowly attenuate, apex obtuse to acute, lateral veins in 2–3(–4) alternate to opposite pairs, arcuate to straight, distal cauline leaf blades linear to narrowly elliptic, 0.6–2.5 × 0.01–0.6 cm, base attenuate to cuneate, apex obtuse to acute, lateral veins not distinct. Flowering pedicels 6–22(–30) mm. Flowers: calyx tube 3.1–6.1 × 2.5–3.2 mm, to 4.9 mm diam. in fruit, inner surface glabrous near base, becoming as pubescent as outer surface near apex and on lobes, outer surface moderately to densely pubescent, lobes 2.1–5 × 1–2.3 mm, apically obtuse; corolla tube 8–13.9 × 5.4–11.2 mm, inner surface glabrous, outer surface sparsely to moderately pubescent, lobes 3.6–4.2 × 3.6–6.2 mm, inner surface glabrous, outer surface sparsely to moderately pubescent; filaments adnate to corolla tube 3.7–4.8 mm beyond base, 4.2–7.5 mm, glabrous; anthers connivent, 0.9–1.1 × 0.8–1 mm; ovary ellipsoid, 1.9–2.3 × 0.9–1.1 mm, glabrous; style 6.7–7.8 mm, glabrous; stigma greenish or yellowish, 0.6–1 × 1.3–2 mm. Capsules 6.8–8 × 4.3–4.9 mm, glabrous or sparsely to moderately pubescent, hairs glandular-capitate. Seeds brown, 0.7–1 × 0.6–0.8 mm, surfaces distinctly alveolate. 2n = 16.

Phenology: Flowering Mar–Nov.

Discussion

Bouchetia erecta is known from central and southern Texas. The single putative record of B. erecta from Mississippi (Warren s.n., USMS) was found to be Jacquemontia tamnifolia (Convolvulaceae).
