Philodendron bernardopazii and P. ricardoi spp. nov. (Araceae) from Espirito Santo State, Brazil

摘要

Two new species of Philodendron - Araceae (Philodendron bernardopazii E. G. Gonc. and Philodendron ricardoi E. G. Gonc.), so far known to be endemic to the Espirito Santo State, Brazil, are here described and illustrated for the first time. Philodendron bernardopazii has been traded as an ornamental plant for more than 30 years, as one of several species popularly called Philodendron "Santa Leopoldina'', because of the Brazilian county where it has been collected. This new species is so far known from two cultivated stocks, both supposedly collected at the same location (around the village of Santa Leopoldina) and if it still exists in nature, it is probably threatened. Philodendron ricardoi has only been observed on rocks around the village of Estrela do Norte where huge populations can be seen growing in rocky outcrops in open areas.
