DIASTATEA (CAMPANULACEAE, LOBELIODEAE), NUEVO GÉNERO PARA LA FLORA ARGENTINA.

The genus Diastatea (Campanulaceae, Lobelioideae) is recorded for the first time for Argentina in antropic enviroments of the Yungas phytogeographic province (Jujuy), between 1,100 and 2,000 m. We describe and illustrate D. micrantha, the only species collected up to now, including a key to discern it from Lobelia xalapensis, its closest taxon. [ABSTRACT FROM AUTHOR]
