Abstract
The study presented in this paper is a taxonomic treatment with an identification key, descriptions and illustrations of Monsteroideae (Araceae) species, located in the Paraná state (Brazil). The specimens were collected from July 2013 to September 2014, identified and deposited at UPCB and UNOP. Sixty-One exsiccates distributed in the herbaria of the Paraná were analyzed, the study revealed that the species: H. rigidifolia, H. salicifolia, M. adansonii and M. praetermissa are native to Brazil, and the exotic E. pinnatum and M. delicious were found in disturbed areas of conservation units. They are represented in this study by illustrative photos for their recognition in the field. Furthermore, the native species M. adansonii is neotropical and distributed in several states of Brazil, while H. rigidifolia, H. salicifolia and M. praetermissa are endemic to Brazil and more restricted to the Atlantic Forest. The Paraná state is the southern limit of geographical distribution for H. salicifolia and M. praetermissa. In Paraná, all native species Monsteroideae are found exclusively in areas of Ombrophylous Dense Forest.
