PrImer regIstro de CatagonIum BrevIcaudatum (catagonIaceae) para la ArgentIna

Abstract

Background and aims: The genus Catagonium includes two species in Argentina: C. nitens y C. nitidum. The aim of this study was recorded Catagonium brevicaudatum Müll. Hal. ex Broth. for Argentina in the National Park Campo de los Alisos, Tucumán. M&M: The specimens were analyzed morphologically using conventional techniques for bryophytes and mounted in Hoyer's solution. Results: It is distinguished from the others species of the genus by foliar characters such as leaves ovate to ovate-oblong, strongly concave, auriculate, and an abruptly piliferous, recurved apex. Conclusions: C. brevicaudatum is described and illustrated, and the differences between this taxon and the other species present in Argentina are shown in a key.
