Luehea eichleri Schumann (1886: 158) .

Type:— BRAZIL. Rio de Janeiro: “ Brasilia ”, Luschnath s.n. (holotype B (destroyed) [F! negative number 9242]) ; Rio de Janeiro: “ Morro do Broco, October 1834 ”, Luschnath s.n. (lectotype, designated here, BR! [ BR0000005491346 ] ; isolectotype BR! [ BR0000005491582 ]) . [= Luehea conwentzii K.Schum. ]

Schumann’s protologue mentions the label data of a specimen collected by Luschnath and preserved in the Herbarium Berolinense (B). Cunha (1985) accepted the specimen Luschnath s.n. (B) as the holotype of L. eichleri (“ Holotypus – B, non vidi”), presumably was not aware that the specimen was destroyed during the Second World War (R. Vogt, pers. comm.). With the presence of two duplicates in BR, in accordance with Art. 9.3 of the ICN, we designate herein the specimen (BR0000005491346) as the lectotype by choosing the best-preserved and completed specimen. After having studied the type materials, the application of the name L. eichleri is confirmed as a heterotypic synonym of L. conwentzii , as previously accepted by Cunha (1985).
