Forsteronia pubescens A. DC., Prodr. View in CoL 8: 436. 1844.

Figure 4C

Liana. Leaf blades 3.1–9.5 × 2.2–5.4 cm, elliptic, oblong, chartaceous, apex acuminate, base obtuse to rounded, pilose on both surfaces. Inflorescence thyrsiform, terminal; peduncle 0.5–1.2 cm long; bracts 1 mm long, ovate to lanceolate, pubescent. Flowers 3–5 mm long; pedicels 1–2 mm long; calyx-lobes 1–1.5 mm long, ovate, acute apex; corolla-lobes 3–4 mm long, white, oblong; stamen filaments 0.2–0.3 mm long, connate and agglutinated to the style, anthers wholly exserted. Follicles 15218 cm long, parallels, submoniliforms.

Forsteronia pubescens View in CoL occurs in Peru, Bolivia, Paraguay, Argentina, and Brazil ( Kinoshita et al. 2005). In Brazil, it is reported in Bahia, Ceará, Distrito Federal, Goiás, Mato Grosso do Sul, Mato Grosso, Paraná and in the states of Southeast Region ( Koch et al. 2015). In Rio Grande do Norte it was collected in areas of shrubby-arboreal Caatinga with stony soil. This species is resembles Forsteronia thyrsoidea (Vell.) Mull. Arg. View in CoL in vegetative traits. However, F. pubescens View in CoL differs from this mainly by the color flowers (white vs greenish-yellow), bracts shape (ovate to lanceolate vs lanceolate to linearlanceolate), calyx-lobes shape (ovate vs lanceolate), follicles position and shape (parallel and submoniliforms vs divaricate and cylindrical), and longer follicles (15–28 vs 14–15 cm). Also, it differs from Forsteronia rufa Mull. Arg. View in CoL by calyx-lobes shape (ovate vs lanceolate), anthers position (exserted vs inserted), and follicle shape (submoniliforms vs moniliforms); from F. velloziana (A.DC.) Woodson View in CoL it differs by calyx-lobes shape (ovate vs lanceolate), anthers position (exserted vs partially exserted), follicles position (parallel vs divaricate), and smaller follicles (15–28 vs 5–10 cm).

Asteraceae

Dasyphyllum sprengelianum (Gardner) Cabrera, Revista Mus. La Plata, Secc. Bot. View in CoL 9(38): 90. 1959.

Figure 3C

Erect shrub 1‒2 m high, branches glabrous, spinose, and geminate spines, straight, perpendicular to the branches. Leaf blades 2.5‒6 × 1.2‒2.2 cm, elliptic to lanceolateelliptic, subcoriaceous, glabrous, 3-nerved, acute at apex or sometimes obtuse, margin entire, attenuate at base. Capitula solitary, sessile; involucre ca 2 cm long, campanulate, involucral bracts forming 8‒10 whorls, margins ciliate, acute apex, external bracts ovate, internal bracts lanceolate, glabrous. Flowers yellow-light; tubular corolla ca 18 mm long, tube glabrous, lobes long setose. Cypselae 8–10 mm long, densely gray tomentose; pappus ca 15 mm long, cream colored.

Dasyphyllum sprengelianum View in CoL was originally described by Gardner (1847) as Flotovia sprengeliana View in CoL from speci- mens from southeastern Brazil. Its distribution ranges from Bolivia, Paraguay to Brazil ( Saavedra 2011). In Brazil, it is recorded from Bahia, Ceará, Pernambuco, Piauí, Rondônia, Tocantins, Distrito Federal, Goiás, Mato Grosso, Minas Gerais and São Paulo ( Saavedra 2015). In Rio Grande do Norte, Dasyphyllum sprengelianum View in CoL was collected on shrubby Caatinga vegetation, growing in rocky soils. This species belongs to the subgenus Dasyphyllum section Macrocephala by having its 3- to 5-veined leaves from the base and anthers with a bilobed apical appendage. It resembles D. donianum (Gardner) Cabrera View in CoL due to its subcoriaceous, glabrous, and shortly petiolate leaves, and by its bracts with hairy margins and densely villous abaxial surface. Dasyphyllum sprengelianum View in CoL differs from D. donianum View in CoL by the shorter spines on the branches (5–18 mm vs 20 mm long), the leaf blade acuminate at apex (vs obtuse and mucronate), and inner involucral bracts lanceolate (vs oblong-lanceolate).
