A new species of Mastigostyla (Iridaceae) from Argentina

Abstract

We describe and illustrate Mastigostyla coronata, a new species of Iridaceae from the high Andes of Jujuy (Argentina), morphologically similar to Mastigostyla vargasii. The inclusion of this new species in Mastigostyla is supported by a phylogenetic analysis based on plastid markers. We also present a morphological comparison among the sub-acaulescent species of Mastigostyla (including Cardenanthus), and a key to those species.
