Turnera confertiflora(Turneraceae), new species from the “cerrado” of Tocantins (Brasil)

Abstract

Turnera confertiflora, a new, apparently homostyle species from Brasil, is described and illustrated. It belongs to Turneraseries Leiocarpae because of its smooth fruits, floriferous leaves with nectaries and immature seeds with epicuticular and stick-shaped wax. Its racemose inflorescences and linear or angusti-elliptic leaves resemble those of T. melochioidesvar. arenariafrom which T. confertifloracan be distinguished by the tomentose indumentum (vs. glabrous or pilose, never tomentose). Floral size and morphology are similar to those of T. angelicae, with pilose petals and staminal filaments, but with glabrous styles (vs. pilose). Turnera confertiflorais known only from the type specimen, collected in stony “cerrado” in Tocantins, municipality of Natividade
