Description:—Terrestrial, or affixed sub-aquatic. Small to medium sized, annual herb. Rhizoids up to 90 mm long. Leaves usually 1(–3) from peduncle base, lamina obovate to circular, 5–55(–65) mm long, traps numerous on rhizoids and stolons, broadly ovoid, 1–2 mm long. Inflorescence simple (240–) 300–750 mm long, peduncle glabrous, 0.5– 1.4mm long, scales basifix, glabrous, deltoid, apex acute, margin entire 1.3–1.5 mm long, bract ovate to deltoid, apex acute c. 1.5 mm long, bracteoles smaller or similar length, lanceolate, connate near the base, or sometimes middle, glabrous. Flowers 1–8, pedicel (1–) 2–4 mm long, calyx lobes unequal, coriaceous, usually glabrous or papillose near margin, rarely with sparse sessile glands, inconspicuous simple nerves, upper lobe ovate-oblong or broadly elliptic to circular, concave, apex rounded, margin entire, hyaline 2.8–3.1 × 2.3–2.7 mm, lower lobe broadly elliptic, entire, margin not hyaline, apex crenate or emarginate, 1.5–2.0 × 2.5–3.1 mm, corolla lilac with yellow spot with white margin at base of lower lip, 10–25 mm long, with papillae and few glandular trichomes, upper lip broadly ovate, apex rounded, equal to about twice the length of calyx lobes, 2.0– 4.3 mm long, lower lip transversally elliptic or broadly obovate, base forming a bilobed swelling, apex entire or shallowly 3-lobed, 6–9 × 8–10 mm, spur slightly conical, apex obtuse, equal or slightly larger than the lower lip, 7.2–8.4 mm long, filaments curved, anther thecae sub-distinct, ovary globose with some glands on the outside wall. Capsule globose up to 4 mm diam. Seeds narrowly cylindrical c. 1 mm long, 0.15 mm wide.

Distribution and ecology: — Argentina, Brazil, Colombia, Uruguay, and Venezuela ( Fig. 1 View FIGURE 1 ). In Brazil, in the states of Bahia, Espirito Santo, Goiás, Maranh„o, Mato Grosso, Minas Gerais, Pará, Paraná, Rio de Janeiro, Rio Grande do Sul, Santa Catarina and S„o Paulo. Grasslands bordering creeks, lakes, gallery forests, veredas (a phytophysiognomy composed of the palm Mauritia flexuosa L.f.), restingas, and campo rupestre. Flowering August to May.

Etymology: —The epithet tricolor refers to the three colors of the corolla, lilac with yellow and white at base of the lower lip.

Conservation status: —Least Concern. Based on its wide distribution (EOO = 8,284,102 km 2, AOO = 132 km 2) and frequent presence in protected/conservation areas, U. tricolor is here considered Least Concern, in accordance with Cross et al. (2020).

Notes: — Utricularia tricolor ( Fig.4I View FIGURE 4 ) is easily distinguished from all other U. sect. Foliosa species by its robust specimens with tall inflorescence scapes and large flowers. The most similar species is U. bicolor (previously a synonym of U. amethystina ), which can be mistaken for U. tricolor from the Espinhaço Range in Minas Gerais, where both taxa are sympatric, and specimens of U. tricolor are often smaller. In some specimens, it is possible to observe a few trichomes and papillae near the calyx margin, one of the defining characters of U. bicolor . However, U. tricolor has a larger corolla with lower lip apex almost entirely or shallowly 3-lobed and glabrous calyx, except in some populations collected from the Espinhaço Range. At this site it is notable that U. bicolor does not possess a white margin surrounding the yellow spot at the base of lower lip, as does U. tricolor . Nevertheless, the material examined during this study suggests hybridisation between these two taxa. It is worth mentioning that these two species are not phylogenetically close, with U. tricolor sister to U. amethystina s.str., and U. bicolor sister to a clade containing the U. hirtella complex ( Baleeiro et al. 2019).
