Two new species of Tynanthus Miers (Bignonieae, Bignoniaceae) from Brazil.


ABSTRACT: Tynanthus is a genus of lianas that is broadly distributed through the Neotropics. Two new species of Tynanthus from Brazil are here described and illustrated: Tynanthusdensiflorus, from Amazonas, and Tynanthusespiritosantensis, from Espírito Santo. Tynanthusdensiflorus is recognized by the conspicuous interpetiolar glandular fields, a feature rarely found in Tynanthus, and the dense thyrses. Tynanthusespiritosantensis, on the other hand, is recognized by the bromeliad-like prophylls of the axillary buds and the lax thyrses. Information on the distribution, conservation status and morphologically similar species are provided.
