Additions to the genus Lessingianthus (Asteraceae, Vernonieae) from South America
Two new species of Lessingianthus (Asteraceae: Vernonieae) are described and illustrated. One of these, L. foliosus Dematt., bears a resemblance to L. vepretorum, but can be separated from itby its linear leaves, that are lanate on the abaxial surface, and by its shorter internodes. The other new sp...

Uma dessas espécies, L. foliosus Dematt., apresenta semelhança com L. vepretorum, mas diferencia-se dela pelas folhas lineares, lanosas na face abaxial e pelos entrenós mais curtos. A outra espécie, L. lapinhensis Dematt., pode ser distinguida facilmente de L. brevifolius e outros táxons do gênero pela combinação de caule 8–18 cm compr., folhas lineares, glabras e invólucro campanulado. Outros treze táxons descritos como Vernonia são transferidos para o gênero Lessingianthus e dois lectótipos são aqui designados. 2025-11-03T12:14:56Z 2025-11-03T12:14:56Z 2010-04 Artículo Dematteis, Massimiliano y Angulo, María Betiana, 2010.
