Figure 4A

Scandent shrub 1‒2 m high. Leaf blades 5‒5.5 × 2‒1.5 cm, membranous, elliptic, base cuneate, apex acute, lower surface lanuginose, upper surface strigose. Inflorescence terminal; flowers whitish-green; bracts ovate, 1‒2 mm long, base truncate, apex acute; bracteoles ovate, 1‒1.8 mm long, no dorsal crest, base truncate, apex acute; tepals 3.3‒3.8 mm long, unequal; lacinia 3-nerved, margin entire, apex acute, entire, dorsal surface lanuginose; staminal tube ca 2.5 mm long; ovary ca 0.5 mm long, ellipsoid.

Gomphrena vaga has a wide distribution in South America ( Senna et al. 2010). In Brazil, it is recorded for the Distrito Federal and the states of Alagoas, Bahia, Ceará, Maranhão, Paraíba, Pernambuco, Piauí, Sergipe, Pará, Tocantins, Goiás, Mato Grosso, Mato Grosso do Sul, Minas Gerais Rio de Janeiro, São Paulo, Paraná, Rio Grande do Sul, and Santa Catarina ( Senna et al. 2015). It is easily recognized by its branched and scandent shrubby habit and leaves with lanuginose indumentum on the abaxial face. In Rio Grande do Norte, it was collected in open areas of shrubby-tree Caatinga on stony soil.

Annonaceae

Oxandra sessiliflora R.E. Fr., Acta Horti Berg. 10: 172, fig. 5f, g. 1931

Figure 4B

Shrub ca 2 m high. Leaf blade 3–6.5 by 1–2.2 cm, narrowly ovate to narrowly obovate, coriaceous, smooth, base obtuse to slightly cordate, apex acute. Flowers in 1- or 2-flowered inflorescences; bracts 4 or 5, depressed ovate, 1–1.3 mm long. Flower buds globose. Fruits not seen.

Endemic species to Brazil, where it is recorded for the states of Bahia, Ceará, Maranhão, Pará, Paraíba, Piauí, Rio de Janeiro, in dry vegetation like Caatinga, Cerrado, sometimes in forest on “terra firme”, on sandy soil ( Junikka et al. 2016). This species is easily recognized by its very small, bright and acute apex leaves, subsessile flowers, and the presence of a dense indument on both young branches and petals ( Junikka et al. 2016). In Rio Grande do Norte, it was collected in areas of shrubby-tree Caatinga on stony soil.
