Summary: The new large tree species Luetzelburgia amazonica D. B. O. S. Cardoso, L. P. Queiroz & H. C. Lima is described, illustrated and discussed based on collections from the state of Rondônia in Brazil. It is the only species of the genus occurring in the Amazon basin. Luetzelburgia amazonica resembles L. trialata (Ducke) Ducke based on the number and morphology of leaflets, fruit size and the dark brown sericeous indumentum on the inflorescence, but differs mainly in its larger flowers, pinkish petals and very distinct standard petal shape. © 2012 The Board of Trustees of the Royal Botanic Gardens, Kew.
