Description:—Terrestrial. Small to medium sized annual herb. Rhizoids absent or 2–4, simple ramification, 3–7 mm long. Stolons few to numerous (10) up to 6 mm long. Leaves absent or up to 7, from peduncle base, lamina obovate, reniform to almost circular, multinerved; 2 mm long; traps on stolons, globose, 0.5–2.0 mm long, stalked 0.5–3.0 mm long. Inflorescence simple or loosely branched, 30–150 mm long, peduncle glabrous 0.19–0.42 mm thick; scales basifix, glabrous, ovate, margin entire 0.5–0.7 mm long, bract and bracteoles basifixed, connate at about the middle, glabrous, without or 1-nerved, bract ovate apex acuminate obtuse, 0.6–1.0 mm long, bracteoles narrowly ovate, shorter or the same level than the bracts. Flowers 1–3 pedicel erect, filiform, glabrous or glandular trichomes next to calyx, 1–9 mm long; calyx lobes unequal, chartaceous, concave, glandular trichomes present, with inconspicuous simple nerves, upper lobe ovate or ovate-elliptic, apex rounded, margin hyaline, entire 1.1–2.1 mm long; lower lobe ovateoblong, margin not hyaline, apex crenate or emarginate, 0.8–1.6 mm long; corolla white, cream, or light pink, with yellow spot at base of lower lip, surfaces hirsute (densely covered by trichomes); upper lip oblong towards the base, ovate towards the rounded apex; lower lip transversally elliptic, base slightly gibbous, apex slightly 3-lobed, lateral and middle lobes rounded; spur conical, apex obtuse, x2> the length of lower lip, trichomes cover much surface 2.2–5.1 mm long; filaments slightly curved, anther thecae same width as filaments; ovary globose, surface covered with glandular or simple trichomes. Capsule globose 1.0– 1.5 mm long., not embracing the style lips. Seeds obliquely ovoid to narrowly cylindrical, 0.2–0.5 × 0.15 mm.

Distribution and ecology: —This group is found in Belize, Brazil, British Guyana, French Guyana, Honduras, Guatemala, Venezuela and Surinam. In Brazil, in the states of Bahia, Goiás, Mato Grosso, Minas Gerais, Roraima, and Tocantins. Although its distribution ranges from Central to South America and across many biogeographical barriers ( Fig. 1A–C View FIGURE 1 ), it is mostly hard to measure population size, and the number of specimens is low, similar nature found in U.trinervia . Specimens grow in sandy, wet, poor soils of mostly high in elevation rocky outcrops and grasslands in the Brazilian and Guiana Shield Savannas and close to sea level savannas of the Amazon so-called campinaranas. Flowers from March to September.

Etymology: —The species epithet refers to the indumentum of simple and glandular trichomes covering the surface of the calyx and corolla.

Conservation status: —Least Concern. Utricularia hirtella s.l. ( Fig.4A–D View FIGURE 4 ) as here defined, is considered to be a species complex with a widespread distribution (EOO = 7,237,840 km 2; AOO = 160 km 2), found within several protected areas. If this complex taxon is further delimited in the future, the additional taxa may require reevaluation of threat status.

Notes: —Although an attempt was made to sample populations representing each of the currently accepted taxa or synonyms of published names ( Baleeiro et al. 2019), none of the accessions in the U. hirtella clade represents the type locality so instead morphologically similar specimens were included ( Fig.4A,B View FIGURE 4 ). The closest or possibly the type location is presented in the study of da Silva et al., (2011) of Serra de Sao Jose and a photo is provided ( Fig. 3A View FIGURE 3 , Silva et al. 2011). In addition, access to populations across many northern regions of South America is limited (i.e., the Tepuis, Venezuela), and further collections are required to examine this species complex of species. In summary, U. hirtella is differentiated from other related taxa by the presence of papillae and/or trichomes on its calyx, and a usually white corolla. At the same time, Baleeiro et al. (2019) study showed U. hirtell a is a multi-lineage independent from U. amethystina s.str. it also revealed a morphological diversity that requires further investigation.
