New boraginaceae from tropical America 3: A new Tournefortia from Ecuador and Colombia

Tournefortia gigantifolia, an unusual understory shrub, is described as new from wet forests in Ecuador and Colombia. It is distinct in its monocaulous or sparsely branched habit with large punctate leaves clustered near the stem apices. Its free anthers and unlobed fruits indicate clearly that it is a member of Tournefortia sect. Tournefortia, but its relationships with other species are not evident.
