10. Utricularia hispida Lamarck (1791: 50) View in CoL ( Fig. 4 View FIGURE 4 : D–G)
Marsh herbs, up to 60 cm tall. Stolons and vegetative parts glabrous. Leaves up to 0.3 mm wide, linear to oblanceolate, apex rounded. Traps lateral, dorso-lateral appendages deltoid and compressed. Inflorescence erect, up to 10-flowered, flowers 0.5–3 cm distant from each other. Peduncle greenish or blackish; lateral spongy floats absent. Sterile bracts up to 1 × ca. 1 mm, basifixed, oblong, apex truncate, equally distributed. Bract up to 2 × ca. 2 mm, basifixed, oblong, apex irregularly denticulate. Bracteoles 1–1.5 mm long, basifixed, filiform. Pedicels nearly 7 mm, longer or equal to the calyx lobes. Calyx lobes equal, 3 × 2 mm, triangular, margin sinuous to irregularly denticulate, without prominent nerves, green, dark red to purple. Corolla pale violet with white and yellow-orange mark on the lower lip; upper lip 5 × 3–4 mm, ovate, apex rounded; lower lip 6 × ca. 8 mm, lacking noticeable lobes; spur ca. 7 × ca. 1 mm, conical, apex acute, longer than the lower lip of corolla and not forming an angle of 90º with the latter in a lateral view. Style and filaments short. Capsule globose, dehiscing by a longitudinal ventral slit. Seeds numerous, ovoid to oblique-ovoid, surface reticulate, testa cells oblong, elliptic or circular.
Distribution:— Utricularia hispida occurs in North ( Mexico), Central and South America ( Taylor 1989). In Brazil it is recorded in the northern, northeastern, central-western and southeastern regions ( Miranda et al. 2016). This species is found in saturated savannas, usually among Poaceae and Cyperaceae , open savannas or in sandy humid soils between rocks ( Taylor 1989). In the VNP it occurs in areas of grassy white-sand savannas, generally as isolated individuals among grasses, up to 60 cm tall.
Taxonomic notes:— Utricularia hispida is distinguishable by its bract and bracteoles with irregularly denticulate margin and the oblong to lanceolate, well-developed lamina (up to 30 cm long).
