An overlooked new species from the Caatinga: Cenostigma lewisii (Leguminosae)

Le résumé fourni par la source

Cenostigma lewisii, a new species from northeastern Brazil, within the Caatinga phytogeographic domain, is here described and illustrated. The new species is morphologically similar to Cenostigma microphyllum, with which it is often confused, but can be distinguished by its glabrous leaf buds (vs. pubescent in C. microphyllum), leaves with 3–6(–7) pairs of pinnae + terminal pinna (vs. 7–13 pairs + terminal pinna), median leaflets 6–10(–16) × 4–7(–10) mm (vs. median leaflets 2–5.1 × 1.2–3.3 mm), inflorescences 7.8–18 cm long (vs. 4.2–7.8 cm long), and glabrescent to sparsely velutinous fruits; glands very sparse when present and non-sticky (vs. sparsely pubescent and densely glandular, sticky fruits). Cenostigma lewisii occurs in sandy Caatinga areas along the Tucano-Jatobá biogeographic district, in the states of Bahia and Pernambuco, and is assessed as Least Concern (LC).
